acpiapm.h

Add the apm(4) subsystem to arm64.

7 years ago

apmvar.h

Simplify the (so far unused) apm_record_event() function a bit and use it to send a resume event to userland when we come out of suspend.

3 years ago

armreg.h

Clean up the interface between ddb and the arm64 trap handler. Introduce code to directly enter DDB when an unexpected exception happens similar to what we already have on amd64, setting the panic message without actually doing a fool panic (which might destroy interesting register state). Mark permanent breakpoints and add code to skip over them.

asm.h

Implement branch target protection using the branch target identification feature introduced in Armv8.5. This provides "head-CFI" to complement the "tail-CFI" provided by retguard. Unfortunately most arm64 machines don't support this feature yet. But Apple M2 does support it and it seems to work there.

cpu.h

avoid including "xcall.h" in cpu.h to avoid confusing userland.

cpufunc.h

Add imxpd(4) which is a power domain controller driver that essentially calls into ATF to make it supply power.

Introduce code to directly enter DDB when an unexpected exception happens similar to what we already have on amd64, setting the panic message without actually doing a fool panic (which might destroy interesting register state).

efivar.h

Hook up the Qualcomm UEFI Secure Application that handles EFI variables to efi(4) such that we can access EFI variables through ioctls on /dev/efi.

endian.h

drop the MD byte-swap micro-optimizations on clang architectures

exec.h

Implement MD corefile notes and use them to write out the PAC note on arm64.

8 months ago

fdt.h

Extend the interrupt API on arm64 and armv7 to be able to pass around a struct cpu_info *. From a driver point of view the fdt_intr_establish_* API now also exist same functions with a *_cpu suffix. Internally the "old" functions now call their *_cpu counterparts, passing NULL as ci. NULL will be interpreted as primary CPU in the interrupt controller code.

fenv.h

Setting and getting the rounding mode on our arm64 FPU has not worked in libm since the rounding mode is in fpcr, not fpsr. Since both FPU registers are 32-bit we can store them in the 64-bit fenv_t to make handling the bits easier.

fpu.h

Implement support for SVE (Scalable Vector Extension) on arm64.

frame.h

Remove strange /* End of file */ style.

hypervisor.h

Implement support for SVE (Scalable Vector Extension) on arm64.

ieee.h

Define EXT_IMPLICIT_NBIT like we do on sparc64 and mips64. Makes vaious long double math stuff (including printf) actually work.

loadfile_machdep.h

change marks[] array to uint64_t, so the code can track full 64-bit details from the ELF header instead of faking it. Proposal from mlarkin, tested on most architectures already

7 years ago

mplock.h

Make arm64 use the MI mplock implementation. Avoid <sys/mplock.h> being pulled in for assembly files by bringing <machine/cpu.h> and <machine/param.h> in line with other architectures. Some minor cleanup of those files is included.

mutex.h

Move common mutex implementations to a MI place.

openpromio.h

openprom(4)

param.h

Add an MI mechanism for creating an (unmapped) guard page between the PCB and the kernel stack. Switch amd64 over to this new mechanism. Also enable these guard pages on other 64-bit architectures with 4k pages (arm64, powerpc64, riscv64).

pci_machdep.h

Handle the case of multiple MCFG table entries for a single segment by checking that the bus number falls within the range of the MCFG entry.

1 year ago

pmap.h

In preparation of moving work from the reaper into exit1(), introduce a new (optional) pmap function that "purges" a pmap to optimize a subsqeuent uvm space teardown. Rewire the arm64 TLB flush optimization to use that new function.

10 months ago

proc.h

Provide mips64 with kernel-facing TCB_{GET,SET} macros that store it in struct mdproc. With that, all archs have those and the __HAVE_MD_TCB macro can be unifdef'ed as always defined.

9 years ago

profile.h

Add support for FIQs. We need these to support agtimer(4) on Apple M1 SoCs since its interrupts seem to be hardwared to trigger an FIQ instead of an IRQ. This means we need to manipulate both the F and the I bit in the DAIF register when enabling and disabling interrupts.

pte.h

remove unneeded vmparam.h include from pte.h include vmparam.h in process_machdep for USER_SPACE_BITS

2 years ago

ptrace.h

Implement support for pointer authentication (PAC) in userland. With PAC it is possible to "sign" pointers with a hidden key. The signature is placed in unused bits of the pointer and can be checked later. This can be used to provide "tail CFI" that is similar to what retguard provides.

2 years ago

reg.h

Revise 'struct fpreg' and dump floating-point register in core dumps. Also reset the floating-point register state upon exec.

9 years ago

reloc.h

R_AARCH64_NONE should be zero, not 256. The latter was a deprecated assignment and isn't used by clang/lld.

signal.h

Bring SROP mitigation to arm64. Make some small modifications to the arm code as well to improve diffability. Changes the types used in the arm64 "struct sigcontext" to avoid having to include <sys/types.h>.

timetc.h

Allwinner hardware sucks! The ARM generic timer on the A64 has a bug where the bottom 9 bits of the counter register can't be trusted if any of the higher bits are rolling over. This is an unpublished errata so the details aren't known. Adopt the same workaround that Linux has.
