riscv64: switch to clockintr

asm.h

Drop unused WEAK_REFERENCE macro

atomic.h

use ansi volatile keyword, not __volatile ok miod@ guenther@

3 years ago

bootconfig.h

Cleanup early bootstrap code. This mostly realigns the code with the FreeBSD code from which it was derived. In particular, it uses the same trick to switch page tables as FreeBSD, which is what we use to spin up the secondary CPUs already. This avoids having to install a temporary 1:1 mapping.

bus.h

Avoid doing cache flush/invalidate operations for DMA memory allocated with the BUS_DMA_COHERENT flag.

Remove unused field d_poll from struct cdevsw.

db_machdep.h

Remove typedef of db_addr_t; mpi converted the users of it to vaddr_t already back in 2019.

endian.h

Do not pretend there exist MD code for byte swapping yet provide copies of the MI fallback code; ok deraadt@ jsg@

fdt.h

Add sfgpio(4), a driver for the GPIO controller found on the SiFive FU740 SoC.

fenv.h

Correct defines for fenv rounding modes and change fenv_t and fexcept_t from unsigned long long to unsigned int.

Fix line swap resulting in misplaced ',' causing build error.

SMP support. Mostly works, but occasionally craps out during boot.

loadfile_machdep.h

File was accidentally duplicated on inital checkin, remove dup.

Using the MI mplock should be fine on riscv64.

param.h

don't define __HAVE_ACPI to unbreak radeondrm build

4 years ago

pcb.h

Simplify the way we track the FPU state, using powerpc64 as a model. The new code still uses the clean/dirty state that the hardware reports to optimize saving/restoring the FPU register, but no longer attempts to keep the FPU registers alive across a context switch. Fixes panics seen on MP kernels.

4 years ago

pci_machdep.h

Use uint64_t instead of u_long for pcitag_t.

4 years ago

pmap.h

Remove obsolete __HAVE_VM_PAGE_MD define - all platforms provide vm_page_md those days, and nothing checks for that symbol anymore.

setjmp.h

On OpenBSD _JBLEN is the number of slots (of type long) in jmp_buf. We don't need 256 slots, so change it to 32 which leaves us with a few spare slots and is probably what was intended.

4 years ago

signal.h

Significant overhaul of the floating point save/restore code. At this point the mechanism should closely resemble the powerpc64 save/restore points with one difference. (reload avoidance) The previous 'aggressive' fpu save code that was (mostly) implemented before and is present on arm32 and arm64.

softintr.h

remove "for all AArch64 platforms" from comment removed from other archs in 2020 before riscv64 was imported

vmparam.h

Aggressively randomize the location of the stack on all 64-bit architectures except alpha. This will put the stack at a random location in the upper 1/4th of the userland virtual address space providing up to 26 additional bits of randomness in the address. Skip alpha for now since it currently puts the stack at a (for a 64-bit architecture) very low address. Skip 32-bit architectures for now as well since those have a much smaller virtual address space and we need more time to figure out what a safe amount of extra randomizations is. These architectures will continue to use a mildly randomized stack address through the existing stackgap random mechanism. We will revisit this after 7.3 is released.
