While I'm here, amd_cpuid_cpu_cacheinfo() is an info function rather
than a probe function.
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.
The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.
caveats, but works quite well in a lot of MP cases, and all
UP cases that I have tested. Parts of this will hopefully be
reworked in the not-too-distant future.
- If we detect SSE/SSE2 support in the CPU, enable SSE exceptions
and set i386_has_{sse,sse2} as appropriate.
- Expose i386_use_fxsave and i386_has_{sse,sse2} through sysctl
as machdep.{osfsxr,sse,sse2}.
- Add "associativity" to the cache_info structure.
- Add a (*cpu_cacheinfo)() function pointer, like we have a
(*cpu_setup)() function pointer. Cache info in the `cpuid'
is vendor-specific.
Remove duplicate prototype for i386_{set,get}_ldt() from sys_machdep.c.
Change i386_iopl() and i386_{set,get}_{ldt,ioperm}() to take a second
argument of "void *" instead of "char *", for consistency with other syscalls.
defined, call addupc_intr() directly from statclock() in the system time case,
using the same P_OWEUPC path if the copyin/copyout fails.
Use this in i386 to remove profiling code from the normal userret() path.
state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.
- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.
and sysctl to export to userland). Also, only use total number of sectors
given in the extended parameters if the physical chs geometry is
marked invalid. Hopefully fixes a problem where BIOSs would not correctly
fill in this field.
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.
