_float.h

create new machine/_float.h which is namespace clean. create a new MI float.h which pulls in and defines the values that are needed from there, and repair sys/limits.h so that it defines the values it needs as well (depending on POSIX version, XPG version, etc). guenther has a more exact selection of that coming for limits.h. this also fixes a few mistakes for the vax. reviewed by kettenis and guenther.

arm, armv7: add clockintr support

apmvar.h

flense more trailing whitespace

armreg.h

Synch the cpu match/attach/identify code with arm64. This drops some information from dmesg that is no longer relevant to ARMv7 CPUs in favour of printing the full architected cache hierarchy in the same way as we do on arm64. It also is another small step towards SMP support on armv7.

asm.h

_C_LABEL() and _ASM_LABEL() are no longer useful in the "everything is ELF" world. Eliminate use of them in amd64, arm64, armv7, i386, macppc, mips64, and sparc64 code.

atomic.h

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

3 years ago

bus.h

Let the armv7 bus_dma layer and simplebus(4) implementation deal with DMA remapping in the same way as arm64. This relies on the dma-ranges property in the device tree and allows us to get rid of the hack for the Raspberry Pi in the dwctwo(4) driver.

6 years ago

cdefs.h

Add __strong_alias macros for all architectures to be able to alias another symbol without weak attribute. To be used in libc and libm soon. Agreed by kettenis@, guenther@, matthew@.

conf.h

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.

4 years ago

disklabel.h

Use #ifndef _MACHINE_DISKLABEL_H_ everywhere. Replace _ARM_DISKLABEL_H_ and _SH_DISKLABEL_H_ with _MACHINE_DISKLABEL_H_. Add the guard to loongson and octeon. The #defines are not used anywhere else in the tree so no functional change.

10 years ago

endian.h

Unify the MD byteswapping code as much as possible across architectures. Use inline functions instead of GNU C statement expressions, and make them available to userland. With clues from guenther@.

7 years ago

exec.h

In exec_elf.c: expand ELFNAME(), ELFNAME2(), and ELFNAMEEND() except leaving out the size, so that ELFNAME2(exec,makecmds) becomes exec_elf_makecmds instead of exec_elf{32,64}_makecmds and then delete the ELFNAME2() and ELFNAMEEND() macros.

9 years 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

Also enclose variable names with external linkage in __BEGIN_DECLS.

fiq.h

Arm port, NetBSD codebase stripped down, 32bit only support.

22 years ago

frame.h

_C_LABEL() and _ASM_LABEL() are no longer useful in the "everything is ELF" world. Eliminate use of them in amd64, arm64, armv7, i386, macppc, mips64, and sparc64 code.

ieeefp.h

Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently.

15 years ago

kcore.h

Kernel crash dump support for arm-based platform, with minimal support in libkvm, but all the necessary information for a complete _kvm_kvatop() is available in the crash dump.

19 years ago

limits.h

Remove SIZE_MAX from limits.h. It was added years ago before we had a proper stdint.h. No ports fallout. OK guenther@ miod@

11 years ago

machdep.h

If the value of r0 upon entering the kernel is zero, interpret this as the address of the end of the symbol table. This will make it possible to get rid of the code in the bootloader that patches up the kernel with the updated esym value.

9 years ago

mplock.h

Make it possible to build a MULTIPROCESSOR kernel on armv7. While this doesn't actually spin up any secondary CPUs, it does run. Mostly a cleanup of <machine/cpu.h> along the lines of what I did earlier on arm64. Makes armv7 use the MI mplock implementation and implements copyin32.

7 years ago

mutex.h

Convert armv7 to MI mutex.

8 years ago

openpromio.h

Implement openprom(4) for armv7.

10 years ago

param.h

Unify and bump some of the NMBCLUSTERS defines. Some archs had it set to 4MB which is far too low especially when the platform is able to run MP. New limits are, amd64 = 256M; arm64, mips64, sparc64 = 64M; alpha, arm, hppa, i386, powerpc = 32M; m88k, sh = 8M Still rather conservative numbers but much better than before. At least some hangs of arm64 build boxes was caused by this. OK kettenis@, visa@

7 years ago

pcb.h

Add kernel support for the VFP FPU/SIMD unit. Based on a diff by drahn@. This allows us to use floating-pointer and vector instructions in userland code. The current implementation assumes all 32 VFP registers are present. This should be the case on all armv7 hardware currently supported by OpenBSD.

8 years ago

pci_machdep.h

Use a 64-bit integer for pcitag_t and define PCITAG_NODE and PCITAG_OFFSET macros to make armv7 build again.

4 years ago

pmap.h

On systems without xonly mmu hardware-enforcement, we can still mitigate against classic BROP with a range-checking wrapper in front of copyin() and copyinstr() which ensures the userland source doesn't overlap the main program text, ld.so text, signal tramp text (it's mapping is hard to distinguish so it comes along for the ride), or libc.so text. ld.so tells the kernel libc.so text range with msyscall(2). The range checking for 2-4 elements is done without locking (because all 4 ranges are immutable!) and is inexpensive.

3 years 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

Modernize arm assembly in the kernel for clang. Based on a similar diff in bitrig. No binary change when compiled with gcc.

signal.h

Save and restore FPU registers around signal handlers. Fixes the random crashes in sh(1).

softintr.h

Remove "for all XXX platforms" from comment. Fixes the issue pointed out by miod@ where the powerpc64 claimed to be "for all AArch64 platforms".

5 years ago

spinlock.h

Move mutex, condvar, and thread-specific data routes, pthread_once, and pthread_exit from libpthread to libc, along with low-level bits to support them. Major bump to both libc and libpthread.

sysarch.h

Remove excessive sys/cdefs.h inclusion ok guenther millert kettenis

sysreg.h

Add macros to access cp14/cp15 registers by name instead of six arguments to instructions. Based on a file from FreeBSD.

trap.h

Remove strange /* End of file */ style.

undefined.h

Store whether or not the VFP was active on entering the unhandled instruction trap and pass it to the VFP fault handler, so that it knows if we faulted with the VFP active or disabled. Reading the status in the VFP fault handler does not work since at that point the VFP already got disabled.
