Calling this configure routine again restores those settings. Dave said he was adding chipsets to this list on an "as needed and tested" basis. I ran across this problem I believe on a Dell Inspiron 4100 with nv11.

Nevertheless, they are still broken. The improvement is to make these drivers use the tiocmget/tiocmset methods, which are present in the 2.6 kernel. Many of these have been incorrectly converted from the old global IRQ locking without regard for SMP issues, or still use the old global IRQ locking methods which are no longer present in 2.6 kernels.

With VRAM, the FIFO can be set to the highest possible setting because there are no latency considerations for other memory accesses. However, in 64 bit bus mode the FIFO preload value must not be set to VIDC20_CTRL_FIFO_28 because this will let the FIFO overflow. See VIDC20 manual page 33 (6.0 Setting the FIFO preload value). * select Multifreq monitor as default, increase frequency range for Multifreq monitor (this is of course a philosophical question, but I believe a sensible default setting should not impose too much limits to the user) (I dropped this change because it is known that some monitor hardware shipped with Acorn machines does not take kindly to wrong timing signals. If people really care, they should use the kernel command line to select the correct monitor type. --rmk) ChangeSet@1.1588.1.8, 2004-02-22 17:00:26+00:00, rmk@flint.arm.linux.org.uk [ARM] Dynamically allocate SA1100 PCMCIA sockets.

This patch is based on the proc-arm925.S in 2.4 kernel, and it has been modified to be more like the ARM926 support in the 2.6 kernel, except for the cache flushing and initialization. Also, this patch fixes the writeback cache flushing for most part. There are still some issues with writeback cache flushing with devices using direct memory access, such as USB OHCI. It is recommended to use the writethrough instead if using USB. This is the default for OMAP-1510. OMAP-1610 does not have these issues, as it uses ARM926 core.

It appears that the show_task function gets called for all tasks, which does not work if one of the tasks is running in a system call on another CPU. In that case the result of thread_saved_pc and show_stack is undefined and likely to cause a crash. For tasks running in user space on other CPUs, show_task() is probably harmless, but I'm not sure if that's true on all architectures. The patch below is still racy for tasks that are about to sleep, but it demonstrates the problem. ChangeSet@1.1557.67.17, 2004-02-19 08:39:53-08:00, akpm@osdl.org [PATCH] show_task() fix and cleanup show_task() is preinting negative numbers for free stack due to arithmetic against the wrong pointer. Fix that up, and clean up a few related things. show_task still has bogus code which atempts to work out how much stack the task has ever used - it cannot work because we don't actually zero out the stack pages when allocating them. We should fix that, or take it out.

Here is the patch I sent before. (The relevant lines from the standard text are cited in http://www.ussg.iu.edu/hypermail/linux/kernel/0310.2/0286.html.

It can be used to explicitly tell the compiler to not inline functions. We need this due to what is, IMO, a bug present in gcc-3.4 and current gcc-3.5 CVS: the compiler is inlining init/main.c:rest_init() inside init/main.c:start_kernel(), despite the fact that thay are declared to be placed in different text sections. ChangeSet@1.1557.67.7, 2004-02-19 08:38:07-08:00, akpm@osdl.org [PATCH] Use -funit-at-a-time on ia32 From: Andi Kleen The upcomming gcc 3.4 has a new compilation mode called unit-at-a-time. What it does is to first load the whole file into memory and then generate the output. This allows it to use a better inlining strategy, drop unused static functions and use -mregparm automatically for static functions. It does not seem to compile significantly slower. This is also available in some of the 3.3 based "hammer branch" compilers used in distributions (at least in SuSE and Mandrake) Some tests show impressive .text shrinkage from unit-at-a-time. e.g. here is the same kernel compiled with -fno-unit-at-a-time and -funit-at-a-time with a gcc 3.4 snapshot. The gains are really impressive: text data bss dec hex filename 4129346 708629 207240 5045215 4cfbdf vmlinux-nounitatatime 3999250 674853 207208 4881311 4a7b9f vmlinux-unitatatime .text shrinks by over 130KB!. And .data shrinks too. At first look the numbers look nearly too good to be true, but they have been verified with several configurations and seem to be real. It looks like we have a lot of stupid inlines or dead functions. I'm really not sure why it is that much better. But it's hard to argue with hard numbers. [A bloat-o-meter comparision between the two vmlinuxes can be found in http://www.firstfloor.org/~andi/unit-vs-no-unit.gz . It doesn't show any obvious candidates unfortunately, just lots of small changes] With the gcc 3.3-hammer from SuSE 9.0 the gains are a bit smaller, but still noticeable (>100KB on .text) This patch enables -funit-at-a-time on ia32 if the compiler is gcc-3.4 or later. We had several reports of gcc-3.3 producing very early lockups. ChangeSet@1.1557.67.6, 2004-02-19 08:37:55-08:00, akpm@osdl.org [PATCH] Add CONFIG for -mregparm=3 From: Andi Kleen , me. Using -mregparm=3 shrinks the kernel further: (compiled with gcc 3.4, without -funit-at-a-time, using the later and together with -Os shrinks .text even more, making over 700KB difference) 4129346 708629 207240 5045215 4cfbdf vmlinux 3892905 708629 207240 4808774 496046 vmlinux-regparm This one helps even more, >236KB .text difference. Clearly worth the effort. This patch adds an option to use -mregparm=3 while compiling the kernel. I did an LTP run and it showed no additional failures over an non regparm kernel. According to some gcc developers it should be safe to use in all gccs that are still supports (2.95 and up) I didn't make it the default because it will break all binary only modules (although they can be fixed by adding a wrapper that calls them with "asmlinkage"). Actually it may be a good idea to make this default with 2.7.1 or somesuch. We add new kbuild infrastructure: the command scripts/gcc-version.sh $(CC) will print out the version of gcc in a canonical 4-digit form suitable for performing numerical tests against.

The current implementation contains several flaws: - it accepts both POISON_BEFORE and POISON_AFTER. check_poison_obj is only called with POISON_AFTER poison bytes. Fix: only accept POISON_AFTER. - the output is unreadable. Fix: use hexdump. - if a large objects is corrupted, then the relevant lines can scroll of the screen/dmesg buffer. Fix: line limit. - it can access addresses behind the end of the object, which can oops with CONFIG_DEBUG_PAGEALLOC. Fix: bounds checks. Additionally, the patch contains the following changes: - rename POISON_BEFORE and POISON_AFTER to POISON_FREE and POISON_INUSE. The old names are ambiguous. - use the new hexdump object function in ptrinfo. - store_stackinfo was called with wrong parameters: it should store caller, i.e. __builtin_return_address(0), not POISON_AFTER in the object. - dump both the object before and after the corrupted one, not just the one after.

The problem in cpio generation is due to the difference in sprintf modifiers on cygwin. The code uses "%08ZX" for strlen of a device node. printf man pages discourages "Z" and has 'z' instead. Both of these are not available on cygwin sprintf (at least some versions of cygwin). The net result of all of this is that the generated file literally contains "ZX" and then the strlen after that and messes up that 110 offset etc. The file is 516 bytes long on the system that I tested and on linux it is 512 bytes. The fix below just uses "%08X" for that field.

The original thread can be found at: http://marc.theaimsgroup.com/?l=linux-ia64&m=106869606922555&w=2 I created the little wrapper function that was requested. I think the only other arch, other than ia64, that doesn't at least include asm-generic/tlb.h is arm. Something appears broken in TLB flushing on IA64 (& possibly other architectures). Functionally, it works but performance is bad on systems with large cpu counts. The result is that TLB flushing in exit_mmap() is frequently being done via IPIs to all cpus rather than with a "ptc" instruction or with a new context..

I think __release_region() must hold a writer lock as well as __request_region() does. A following patch fixes the issue in my environment.

Turns out that the "offset" argument is off_t instead of loff_t. It isn't used at all (unfortunately), but it _is_ checked for sanity, so that's where the error came from. ChangeSet@1.1557.1.81, 2004-02-18 20:55:17-08:00, akpm@osdl.org [PATCH] drivers/char/vt possible race From: Benjamin Herrenschmidt I falled again on the crash in con_do_write() with driver->data beeing NULL. It happens during boot, when userland is playing open/close games with tty's, I was intentionally typing keys like mad during boot trying to trigger another problem when this one poped up. Looking at the code, I'm not sure how protected we are by the above (tty) layer, paulus told me to not rely on anything like locking coming from there, so I decided to extend the scope of the console semaphore one more bit to cover races between calls to con_open, con_close and con_write. Note that in con_do_write, I intentionally drop the semaphore to avoid keeping it held when waiting on the local buffer, and I added some sanity checks on tty->driver_data with some printk's in case we still have an open race by the tty layer. At least, now, the couple vc_allocated & tty->driver_data should be protected though.

For example, the only task in the group where init is group leader is itself: gen2 02:50:44 ~: ls /proc/1/task 1 However, I can then read the contents of 'stat' for any other task in the system: gen2 02:49:45 ~: cat /proc/1/task/$$/stat 1669 (bash) S 1668 1669 1669 34816 1730 256 1480 6479 12 4 8 5 5 17 15 0 1 0 +8065 3252224 451 4294967295 134512640 134955932 3221225104 3221222840 +4294960144 0 65536 3686404 1266761467 3222442959 0 0 17 0 0 0 I had a look at fs/proc/base.c and found that the 'lookup' functions for these directories were checking that the task in question existed, but overlooked the following: 1. In the function proc_pid_lookup, a check is required to ensure that the task in question is a thread group leader. Without the check, any task can have its data retrieved accordingly. Consider the following. There is a multithreaded process 1777. gen2 23:22:47 /proc/1777: ls task 1777 1778 1779 1780 1781 1782 1783 1784 1785 1786 1787 1788 However, I can read the stat file for its thread 1778 as follows: gen2 23:22:50 /proc/1777: cat /proc/1778/stat 1778 (multithreadtest) T 1777 1777 1672 34816 1672 64 0 0 0 0 14 17 0 0 15 0 12 0 8871 24727552 104 4294967295 134512640 134515104 3221222496 1077365276 4294960144 0 0 0 0 3222479248 0 0 -1 1 0 0 But 1778 is not meant to show up in /proc/, as intended right?: gen2 23:22:56 /proc/1777: ls /proc/ 1 1365 1661 1793 881 dma kcore scsi 10 1371 1662 18 9 driver kmsg self 1014 1372 1663 2 909 execdomains loadavg slabinfo 1032 14 1664 3 963 fb locks stat 1062 15 1665 4 966 filesystems mdstat swaps 1066 16 1666 5 buddyinfo fs meminfo sys 1067 1605 1669 6 bus ide misc sysrq-trigger 1087 1610 1670 7 cmdline interrupts modules sysvipc 1095 1611 1671 736 cpuinfo iomem mounts tty 11 1641 1672 8 crypto ioports mtrr uptime 12 1658 17 807 devices irq net version 13 1660 1777 810 diskstats kallsyms partitions vmstat 2. The other part of the bug is in the function proc_task_lookup. Here there needs to be a check that the task X is indeed a thread of the thread group Y when we read /proc//task/.

Unfortunately, this happens before the console is initialized, so all you get is a kernel that dies quickly, for no apparent reason.

From: NeilBrown With this patch, md used two major numbers for arrays. One Major is number 9 with name 'md' have unpartitioned md arrays, one per minor number. The other Major is allocated dynamically with name 'mdp' and had on array for every 64 minors, allowing for upto 63 partitions. The arrays under one major are completely separate from the arrays under the other. The preferred name for devices with the new major are of the form: /dev/md/d1p3 # partion 3 of device 1 - minor 67 When a paritioned md device is assembled, the partitions are not recognised until after the whole-array device is opened again. A future version of mdadm will perform this open so that the need will be transparent.

This patch uses to bio_add_page to honour those restrictions and ups the limit on request size to 64K. This has a measurable impact on rebuild speed (25M/s -> 60M/s) ChangeSet@1.1557.1.57, 2004-02-18 20:51:40-08:00, akpm@osdl.org [PATCH] md: Avoid unnecessary bio allocation during raid1 resync From: NeilBrown For each resync request, we allocate a "r1_bio" which has a bio "master_bio" attached that goes largely unused. We also allocate a read_bio which is used. This patch removes the read_bio and just uses the master_bio instead. This fixes a bug wherein bi_bdev of the master_bio wasn't being set, but was being used. We also introduce a new "sectors" field into the r1_bio as we can no-longer rely in master_bio->bi_sectors.

So rename "write_bios" to "bios" and store the pointer to the read bio in there.

This means modifying the original. If the kmalloced data forms part of the key, then we must not move the data out until after the key isn't needed any more. So this patch moves the call to "INIT" on a new item (which fills in the key) to *after* the item has been found (or not), and also makes sure we only call the HASH function once. Thanks to "J.

This will enable large coredump for everybody. Apparently the 32bit gdb/binutils cannot handle them, but I hear the binutils people are working on fixing that. I doubt it will harm people - unreadable coredumps are not worse than no coredump and it won't make any difference in space usage if you get a 1.99GB or a 2.5GB coredump. So just enable it unconditionally. If it should be really a problem for 32bit the rlimit defaults in resource.h could be changed. For file systems that don't support O_LARGEFILE you should just get an truncated coredumps for big address spaces.

This prevents both deadlock with devfs_lookup by allowing it to drop i_sem consistently and oops in d_instantiate by ensuring that it always runs protected - remove dead code that deals with major number allocation. The only remaining user was devfs itself and patch changes it to - use register_chardev to get device number for internal /dev/.devfsd and /dev/.statd. - remove dead auto allocation flag as well - remove code that does module get on dev open - it is handled by fops_get. Use init_special_inode consistently - get rid of struct cdev_type and bdev_type - both have just single dev_t now ChangeSet@1.1557.1.43, 2004-02-18 20:49:34-08:00, akpm@osdl.org [PATCH] snprintf fixes From: Juergen Quade Lots of places in the kernel are using [v]snprintf wrongly: they assume it returns the number of characters copied.

What we found is it's not a problem for x86 (and most other architectures) because __get_free_pages won't be able to get anything beyond order MAX_ORDER-1 (10) which means at most those hash tables are 4MB each (assume 4K page size). However, on ia64, in order to support larger hugeTLB page size, the MAX_ORDER is bumped up to 18, which now means a 2GB upper limits enforced by the page allocator (assume 16K page size). PPC64 is another example that bumps up MAX_ORDER. Last time I checked, the tcp ehash table is taking a whooping (insane!) 2GB on one of our large machine. dentry and inode hash tables also take considerable amount of memory. Setting the size of these tables is difficult: they need to be constrained on many-zone ia64 machines, but this could cause significant performance problems when there are (for example) 100 million dentries in cache. Large-memory machines which do not slice that memory up into huge numbers of zones do not need to run the risk of this slowdown. So the sizing algorithms remain essentially unchanged, and boot-time options are provided which permit the tables to be scaled down.

Current usage is only done at boot, so this distinction doesn't matter, but it's a bad example to set. This also means that the migration threads do not have to be higher priority than the others, since they are ready to go before any CPU_ONLINE callbacks are done. This patch is experimental but fairly straight foward: I haven't been able to test it since extracting it from the hotplug cpu code, so it's possible I screwed something up.

However, it does nothing, and even with the full hotplug CPU patch, it still does nothing. Simple counters very rarely need anything done when CPUs come up or go down. If you have per-cpu caches, or per-cpu threads, you need to do something. But very rarely for stats. ChangeSet@1.1557.1.28, 2004-02-18 20:47:11-08:00, akpm@osdl.org [PATCH] kthread primitive From: Rusty Russell These two patches provide the framework for stopping kernel threads to allow hotplug CPU. This one just adds kthread.c and kthread.h, next one uses it. Most importantly, adds a Monty Python quote to the kernel. Details: The hotplug CPU code introduces two major problems: 1) Threads which previously never stopped (migration thread, ksoftirqd, keventd) have to be stopped cleanly as CPUs go offline. 2) Threads which previously never had to be created now have to be created when a CPU goes online. Unfortunately, stopping a thread is fairly baroque, involving memory barriers, a completion and spinning until the task is actually dead (for example, complete_and_exit() must be used if inside a module). There are also three problems in starting a thread: 1) Doing it from a random process context risks environment contamination: better to do it from keventd to guarantee a clean environment, a-la call_usermodehelper. 2) Getting the task struct without races is a hard: see kernel/sched.c migration_call(), kernel/workqueue.c create_workqueue_thread(). 3) There are races in starting a thread for a CPU which is not yet online: migration thread does a complex dance at the moment for a similar reason (there may be no migration thread to migrate us). Place all this logic in some primitives to make life easier: kthread_create() and kthread_stop(). These primitives require no extra data-structures in the caller: they operate on normal "struct task_struct"s. Other changes: - Expose keventd_up(), as keventd and migration threads will use kthread to launch, and kthread normally uses workqueues and must recognize this case. - Kthreads created at boot before "keventd" are spawned directly. However, this means that they don't have all signals blocked, and hence can be killed. The simplest solution is to always explicitly block all signals in the kthread. - Change over the migration threads, the workqueue threads and the ksoftirqd threads to use kthread. - module.c currently spawns threads directly to stop the machine, so a module can be atomically tested for removal. - Unfortunately, this means that the current task is manipulated (which races with set_cpus_allowed, for example), and it can't set its priority artificially high. Using a kernel thread can solve this cleanly, and with kthread_run, it's simple. - kthreads use keventd, so they inherit its cpus_allowed mask. Unset it. All current users set it explicity anyway, but it's nice to fix. - call_usermode_helper uses keventd, so the process created inherits its cpus_allowed mask. Unset it. - Prevent errors in boot when cpus_possible() contains a cpu which is not online (ie. a cpu didn't come up). This doesn't happen on x86, since a boot failure makes that CPU no longer possible (hacky, but it works). - When the cpu fails to come up, some callbacks do kthread_stop(), which doesn't work without keventd (which hasn't started yet). Call it directly, and take care that it restores signal state (note: do_sigaction does a flush on blocked signals, so we don't need to repeat it).

Unlike the Time Stamp Counter, it is a reliable timing source which does not get affected by aggressive powermanagement features like CPU frequency scaling. Some ideas and some code are based on Arjan van de Ven's implementation for 2.4, and on R. Byron Moore's drivers/acpi/hardware/hwtimer.c. We also replace the loop based delay_pmtmr with a TSC based delay_pmtmr, which resolves a number of issues caused by the loop based delay. Unsynced TSCs as well frequency changing TSCs will effect the length of __delay(), but it seems this method works best.

The current pppd code use a empty filter (uprog.len=0) to detach the filter in the kernel, but this code was removed in 2.5.71 while fixing a compiler warning. Here the new patch, also with better limit checking. The second patch check for flen == 0 in the filter check too, since later in this code a filter[flen - 1] access is done, which is not so funny with flen 0. Maybe it's not really needed anymore, since with the first patch it would not longer called with flen=0. paulus says: It looks correct. Previously we had (and in 2.4 we still have) if (uprog.len > 0 && uprog.len < 65536) { ... which gave warnings since uprog.len is unsigned short.

If the device had called netif_stop_queue it will never call netif_wake_queue in the interrupt routine (at least on an IA32 system) due to 32-bit wrap around arithmetic. On my IA32 system 'dirty_tx > lp->cur_tx - TX_RING_SIZE + 2' would always evaluate to false when dirty and cur_tx were less than 15, preventing netif_wake_queue to be called. By starting dirty_tx and cur_tx at 0xfffffff0 (to reduce test time) I found that once cur_tx wrapped to zero, that transmitted buffers would never be unmapped or freed because 'while (dirty_tx < lp->cur_tx) {' was not true. cur_tx would keep incrementing (in start_xmit) but dirty_tx would not (in pcnet32_interrupt), thus leaking skb's and pci map entries. On PPC machines, the system would quickly run out of pci maps. Fix tested on PPC and IA32.

This is needed on multi-node systems where the CPU ITCs are not synchronized, causing possible time inconsistencies. This release fixes one last minor think-o and ran overnight without any time inconsistencies (when used in conjunction w/ the time-interpolator-fix_A0 patch).

The only important change is that it handles the overcurrent indicator bits on VIA controllers properly; they are reported using the opposite sense from Intel controllers. Report the OverCurrent status bits in the /proc debugging file and spontaneously change the use of whitespace. Remove unused variable in uhci_hub_status_data(). Report OverCurrent status for VIA controllers properly (the meaning of the status bit is inverted with respect to Intel controllers). Save the port status I/O address in a variable rather than recalculating it many times. Merge code for handling SetHubFeature and ClearHubFeature since we don't implement either one. Remove some unnecessary comments. Remove redundant min_t calculation. ChangeSet@1.1557.53.25, 2004-02-18 15:05:01-08:00, stern@rowland.harvard.edu [PATCH] USB: Improve UHCI root hub code: descriptor, OC bits, etc. This patch is from David Brownell. UHCI root hub updates ... minor bugfixes and cleanups, improving conformance with the USB hub specification. - UHCI doesn't support any kind of power switching; so modify the hub descriptor to stop claiming it does! Likewise fail attempts to disable power on any port. - Intel defined both overcurrent status overcurrent-change bits, but the current code only knows about one. Modify hub descriptor to report per-port overcurrent protection; and use both bits. - Modify the port status set/clear macros to know about the bits that must always be written as zero, and the write-to-clear bits. Update callers which wrote "set" instead of "clear". - Rewrote code returning port status; magic numbers are gone. - Driver can't really support 8 root hub ports; don't try. Also moves the #define DEBUG earlier so that it can kick in any of the various debug macros ... like pr_debug() and dev_dbg().

The ISO scheduler is modified to use that support for full speed transfers ... though nothing will yet ask it to do that. It also tracks schedule depth, to help avoid accepting ISO URBs which need more time than currently remains unscheduled.

CDC Ethernet is vendor-neutral, and preferred (except by MSFT). The initial version didn't catch RNDIS because it cloaks its ethernet links as a kind of CDC ACM (modem) device.

This patch contains the implementation of the I/O Slot DLPAR Drivers for PPC64 RISC Platform Architecture. This module depends on the RPA PCI Hotplug Module in the previous post. The patch is made against kernel version 2.6.3-rc2. The Dynamic Logical Partitioning Module allows the runtime movement of I/O Slots between logical partitions. An administrator can logically add/remove PCI Buses to/from a PPC64 partition at runtime. These operations are initiated using interface files located at: /sys/bus/pci/pci_hotplug_slots/control/ Development contact for this module is John Rose (johnrose@austin.ibm.com).

It requires a few minor changes outside arch/x86_64, which I am sending separately. This patch is needed to boot an 64bit kernel on a 64-bit capable Prescott machine. The ugliest part is probably the swiotlb code. In fact the code for that is not even included, but just reused from IA64. swiotlb implements the PCI DMA API using bounce buffering. I don't like this at all, but there was no other way to support non DAC capable hardware (like IDE or USB) on machines with >3GB. Please redirect all flames for that to the Intel chipset designers. ChangeLog: - Add Kconfig options for PSC - Add support to reuse microcode driver from i386 (Suresh B Siddha) - Try to optimize for the selected CPU - Fix early CPUID check for Intel CPUs (Suresh B Siddha) - Fix GDT to use the configured cache line size for padding - Support monitor/mwait idle loop - Support HyperThreading - Support Intel CPUID flags - Remove all 3dnow prefetches - Add alternative() for the prefetchw prefetch inline. - Include P4 driver in oprofile - Support Intel NOPs in alternative ChangeSet@1.1557.61.4, 2004-02-18 11:40:45-08:00, ambx1@neo.rr.com [PATCH] PCI: remove unused defines in pci.h It occured to me that we also have the following related code in pci.h: Perhaps this should be removed as well?
