* Add support for the extended FPU states on amd64, both for nativeKonstantin Belousov2012-01-213-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 64bit and 32bit ABIs. As a side-effect, it enables AVX on capable CPUs. In particular: - Query the CPU support for XSAVE, list of the supported extensions and the required size of FPU save area. The hw.use_xsave tunable is provided for disabling XSAVE, and hw.xsave_mask may be used to select the enabled extensions. - Remove the FPU save area from PCB and dynamically allocate the (run-time sized) user save area on the top of the kernel stack, right above the PCB. Reorganize the thread0 PCB initialization to postpone it after BSP is queried for save area size. - The dumppcb, stoppcbs and susppcbs now do not carry the FPU state as well. FPU state is only useful for suspend, where it is saved in dynamically allocated suspfpusave area. - Use XSAVE and XRSTOR to save/restore FPU state, if supported and enabled. - Define new mcontext_t flag _MC_HASFPXSTATE, indicating that mcontext_t has a valid pointer to out-of-struct extended FPU state. Signal handlers are supplied with stack-allocated fpu state. The sigreturn(2) and setcontext(2) syscall honour the flag, allowing the signal handlers to inspect and manipilate extended state in the interrupted context. - The getcontext(2) never returns extended state, since there is no place in the fixed-sized mcontext_t to place variable-sized save area. And, since mcontext_t is embedded into ucontext_t, makes it impossible to fix in a reasonable way. Instead of extending getcontext(2) syscall, provide a sysarch(2) facility to query extended FPU state. - Add ptrace(2) support for getting and setting extended state; while there, implement missed PT_I386_{GET,SET}XMMREGS for 32bit binaries. - Change fpu_kern KPI to not expose struct fpu_kern_ctx layout to consumers, making it opaque. Internally, struct fpu_kern_ctx now contains a space for the extended state. Convert in-kernel consumers of fpu_kern KPI both on i386 and amd64. First version of the support for AVX was submitted by Tim Bird <tim.bird am sony com> on behalf of Sony. This version was written from scratch.

* Remove the usage of pc_other_cpus from amd64.Attilio Rao2011-06-211-1/+2

* Commit the support for removing cpumask_t and replacing it directly withAttilio Rao2011-05-051-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cpuset_t objects. That is going to offer the underlying support for a simple bump of MAXCPU and then support for number of cpus > 32 (as it is today). Right now, cpumask_t is an int, 32 bits on all our supported architecture. cpumask_t on the other side is implemented as an array of longs, and easilly extendible by definition. The architectures touched by this commit are the following: - amd64 - i386 - pc98 - arm - ia64 - XEN while the others are still missing. Userland is believed to be fully converted with the changes contained here. Some technical notes: - This commit may be considered an ABI nop for all the architectures different from amd64 and ia64 (and sparc64 in the future) - per-cpu members, which are now converted to cpuset_t, needs to be accessed avoiding migration, because the size of cpuset_t should be considered unknown - size of cpuset_t objects is different from kernel and userland (this is primirally done in order to leave some more space in userland to cope with KBI extensions). If you need to access kernel cpuset_t from the userland please refer to example in this patch on how to do that correctly (kgdb may be a good source, for example). - Support for other architectures is going to be added soon - Only MAXCPU for amd64 is bumped now The patch has been tested by sbruno and Nicholas Esborn on opteron 4 x 12 pack CPUs. More testing on big SMP is expected to came soon. pluknet tested the patch with his 8-ways on both amd64 and i386.

* - Merge savectx2() with savectx() and struct xpcb with struct pcb. [1]Jung-uk Kim2010-08-023-67/+59
| | | | | | | | | | | | | | | | | savectx() is only used for panic dump (dumppcb) and kdb (stoppcbs). Thus, saving additional information does not hurt and it may be even beneficial. Unfortunately, struct pcb has grown larger to accommodate more data. Move 512-byte long pcb_user_save to the end of struct pcb while I am here. - savectx() now saves FPU state unconditionally and copy it to the PCB of FPU thread if necessary. This gives panic dump and kdb a chance to take a look at the current FPU state even if the FPU is "supposedly" not used. - Resuming CPU now unconditionally reinitializes FPU. If the saved FPU state was irrelevant, it could be in an unknown state. Suggested by: bde [1] Notes: svn path=/head/; revision=210777
