Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

sched/headers: Prepare for new header dependencies before moving code to <linux/sched/signal.h> We are going to split <linux/sched/signal.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/signal.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

[IA64] fix getpid and set_tid_address fast system calls for pid namespaces The sys_getpid() and sys_set_tid_address() behavior changed from return current->tgid to struct pid *pid; pid = current->pids[PIDTYPE_PID].pid; return pid->numbers[pid->level].nr; But the fast system calls on ia64 still operate the old way. Patch them appropriately to let ia64 work with pid namespaces. Besides, this is one more step in deprecating of pid and tgid on task_struct. The fsys_getppid() is to be patched as well, but its logic is much more complex now, so I will make it later. One thing I'm not 100% sure is the trick with the IA64_UPID_SHIFT. On order to access the pid->level's element of an array I have to perform the following calculations pid + sizeof(struct upid) * pid->level The problem is that ia64 can only multiply float point registers, while all the offsets I have in code are in rXX ones. Fortunately, the sizeof(struct upid) is 32 bytes on ia64 (and is very unlikely to ever change), so the calculations get simpler: pid + pid->level << 5 So, I introduce the IA64_UPID_SHIFT and use the shl instruction. I also looked at how gcc compiles the similar place and found that it makes it with shift as well. Is this OK to do so? Tested with ski emulator with 2.6.24 kernel, but fits 2.6.25-rc4 and 2.6.25-rc4-mm1 as well.

[IA64] Move include/asm-ia64 to arch/ia64/include/asm After moving the the include files there were a few clean-ups: 1) Some files used #include <asm-ia64/xyz.h>, changed to <asm/xyz.h> 2) Some comments alerted maintainers to look at various header files to make matching updates if certain code were to be changed. Updated these comments to use the new include paths. 3) Some header files mentioned their own names in initial comments. Just deleted these self references.

cputime: Generic on-demand virtual cputime accounting If we want to stop the tick further idle, we need to be able to account the cputime without using the tick. Virtual based cputime accounting solves that problem by hooking into kernel/user boundaries. However implementing CONFIG_VIRT_CPU_ACCOUNTING require low level hooks and involves more overhead. But we already have a generic context tracking subsystem that is required for RCU needs by archs which plan to shut down the tick outside idle. This patch implements a generic virtual based cputime accounting that relies on these generic kernel/user hooks. There are some upsides of doing this: - This requires no arch code to implement CONFIG_VIRT_CPU_ACCOUNTING if context tracking is already built (already necessary for RCU in full tickless mode). - We can rely on the generic context tracking subsystem to dynamically (de)activate the hooks, so that we can switch anytime between virtual and tick based accounting. This way we don't have the overhead of the virtual accounting when the tick is running periodically. And one downside: - There is probably more overhead than a native virtual based cputime accounting. But this relies on hooks that are already set anyway.

[IA64] VIRT_CPU_ACCOUNTING (accurate cpu time accounting) This patch implements VIRT_CPU_ACCOUNTING for ia64, which enable us to use more accurate cpu time accounting. The VIRT_CPU_ACCOUNTING is an item of kernel config, which s390 and powerpc arch have. By turning this config on, these archs change the mechanism of cpu time accounting from tick-sampling based one to state-transition based one. The state-transition based accounting is done by checking time (cycle counter in processor) at every state-transition point, such as entrance/exit of kernel, interrupt, softirq etc. The difference between point to point is the actual time consumed during in the state. There is no doubt about that this value is more accurate than that of tick-sampling based accounting.

[PATCH] MCA/INIT: use per cpu stacks The bulk of the change. Use per cpu MCA/INIT stacks. Change the SAL to OS state (sos) to be per process. Do all the assembler work on the MCA/INIT stacks, leaving the original stack alone. Pass per cpu state data to the C handlers for MCA and INIT, which also means changing the mca_drv interfaces slightly. Lots of verification on whether the original stack is usable before converting it to a sleeping process. Signed-off-by: Keith Owens <kaos@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[IA64] Sanitize assembler code for ia64_sal_os_state struct ia64_sal_os_state has three semi-independent sections. The code in mca_asm.S assumes that these three sections are contiguous, which makes it very awkward to add new data to this structure. Remove the assumption that the sections are contiguous. Define a macro to shorten references to offsets in ia64_sal_os_state. This patch does not change the way that the code behaves. It just makes it easier to update the code in future and to add fields to ia64_sal_os_state when debugging the MCA/INIT handlers.
