Ordinarily, this is identical to the value in the local APIC's ID register, because nearly all BIOSes accept the HW assigned value. Our systems, made up of individual building blocks, can't do that. Each node boots as a separate system and is joined together by the BIOS. Thus, the BIOS rewrites the local APIC ID register with a new value. Potomac and Nocona chips have a mechanism by which the BIOS writer can change bits 7:5 to match the assigned cluster ID. Bits 2:0 come from the thread ID. However, bits 4:3 are still those latched at reset. Oops! Summary: Large clustered systems can't use cpuid to derive the sibling information. Fix: Use the local APIC ID. That's the value we use to online the CPUs, so it had better be OK. For non-clustered systems, cpuid == local APIC, so nothing but large boxes should be affected.

This manifests itself in two ways, one worse than the other. In the single-threaded case, it just fails to clear out the timers on exec. POSIX says that exec clears out the timers from timer_create (though not the setitimer ones), so it's wrong that a lingering timer could fire after exec and kill the process with a signal it's not expecting. In the multi-threaded case, it not only leaves lingering timers, but it leaks them entirely when it replaces signal_struct, so they will never be freed by the process exiting after that exec. The new per-user RLIMIT_SIGPENDING actually limits the damage here, because a UID will fill up its quota with leaked timers and then never be able to use timer_create again (that's what my test program does). But if you have many many untrusted UIDs, this leak could be considered a DoS risk.

This means we can set the offset to invalid and keep the IO bitmap of that task, and switch back to a valid offset (without any copying) when switching back to that task. (or do a copy if there is another ioperm task we switch to.) I've attached ioport-cache-2.6.8.1.patch that implements this. When there's a single active ioperm() using task in the system then the context-switch overhead is very low and constant: # ./ioperm-latency default no ioperm: scheduling latency: 2478 cycles turning on port 80 ioperm: scheduling latency: 2499 cycles turning on port 65535 ioperm: scheduling latency: 2481 cycles This single-ioperm-user situation matches 99% of the actual ioperm() usage scenarios and gets rid of any copying whatsoever - without relying on any fault mechanism.

Anton Blanchard got several oops'es from hvc_write() accessing NULL as if it were a pointer to an hvc_struct usually stored in tty->driver_data. So this patch checks tty->driver_data in hvc_write() before it is used. Hopefully once Alan Cox's patch is checked in ldisc writes won't continue to happen after tty closes. Anton Blanchard has tested this patch and is unable to reproduce the oops with it applied. Changelog: drivers/char/hvc_console.c - Added comment to hvc_close() to explain the reason for NULLing tty->driver_data. - Added check to hvc_write() to verify that tty->driver_data is valid (NOT NULL) which would be the case if the write operation was invoked after a tty close was initiated on the tty.

We need this in community kernels for diagnostic and performance tools to use, especially on very large machines. This patch registers a dynamic misc device "sn_hwperf" that supports an ioctl interface for reading/writing memory mapped registers on Altix nodes and routers via the new SAL call. It also creates a read-only procfs file "/proc/sgi_sn/sn_topology" to export NUMA topology and Altix hardware inventory. > What tools are using this? Performance Co-Pilot http://oss.sgi.com/projects/pcp in particular, pmshub, shubstats and linkstat. Numerous other users include anything that needs knowledge of numa topology/interconnect in order to perform well, e.g. mpt. BTW I have not exported any API functions .. at this point I don't think we need any modules to call the API.

Then it switches only supported architecture left (ppc/ppc64/arm) from dereferencing pointers to __raw_{read,write}[bwl]. Third part is fixing sparse complaints: add __iomem here and there, and switch one 1bit bitfield from int to unsigned int. After this there should be no sparse complaints in matroxfb.

Nowhere in POSIX nor anywhere else specifies this field in siginfo_t. When Ulrich and I hashed out the system call interface we wanted, we looked at siginfo_t and decided there was plenty of space to throw in si_rusage. Well, it turns out we didn't check the 64-bit platforms. There struct rusage is ridiculously large (lots of longs for things that are never in a million years going to hit 2^32), and my changes bumped up the size of siginfo_t. Changing that size is more trouble than it's worth. This patch reverts the changes to the siginfo_t structure types, and no longer provides the rusage details in SIGCHLD signal data. Instead, I added a fifth argument to the waitid system call to fill in rusage. waitid is the name of the POSIX function with four arguments. It might make sense to rename the system call `waitsys' to follow SGI's system call with the same arguments, or `wait5' in the mindless tradition. But, feh. I just added the argument to sys_waitid, rather than worrying about changing the name in all the tables (and choosing a new stupid name).
