- Allocate memory for wakeup code after ACPI bus is attached. The early
memory allocation hack was inherited from i386 but amd64 does not need it.
- Exclude real mode IVT and BDA explicitly. Improve comments about memory
allocation and reason for the exclusions. It is a no-op in reality, though.
- Remove an unnecessary CLD from wakeup code and re-align.
Introduce the x86 kernel interfaces to allow kernel code to use
FPU/SSE hardware. Caller should provide a save area that is chained
into the stack of the areas; pcb save_area for usermode FPU state is
on top. The pcb now contains a pointer to the current FPU saved area,
used during FPUDNA handling and context switches. There is also a
facility to allow the kernel thread to use pcb save_area.
Change the dreaded warnings "npxdna in kernel mode!" into the panics
when FPU usage is not registered.
Use the fpu_kern_enter() interface to properly separate usermode FPU
context from in-kernel execution of padlock instructions and to handle
spurious FPUDNA exceptions that sometime are raised when doing padlock
calculations.
Remove unused i586 optimized bcopy/bzero/etc implementations that utilize
FPU registers for copying. Remove the switch table and jumps from
bcopy/bzero/... to the actual implementation.
As a side-effect, i486-optimized bzero is removed.
Remove the support for int13 FPU exception reporting on i386. It is
believed that all 486-class CPUs FreeBSD is capable to run on, either
have no FPU and cannot use external coprocessor, or have FPU on the
package and can use #MF.
After the FPU use requires #MF working due to INT13 FPU exception handling
removal, MFi386 r209198:
Use critical sections instead of disabling local interrupts to ensure
the consistency between PCPU fpcurthread and the state of FPU.
Re-implement FPU suspend/resume for amd64. This removes superfluous uses
of critical_enter(9) and critical_exit(9) by fpugetregs() and fpusetregs().
Also, we do not touch PCB flags any more.
Fix another fallout from r208833. savectx() is used to save CPU context
for crash dump (dumppcb) and kdb (stoppcbs). For both cases, there cannot
have a valid pointer in pcb_save. This should restore the previous
behaviour.
- Merge savectx2() with savectx() and struct xpcb with struct pcb. [1]
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.
savectx() has not been used for fork(2) for about 15 years. [1]
Do not clobber FPU thread's PCB as it is more harmful. When we resume CPU,
unconditionally reload FPU state.
