Subject: [PATCH v4 00/36] bsd-user: arm (32-bit) support
Date: Thu, 4 Nov 2021 21:18:41 -0600 [thread overview]
Message-ID: <20211105031917.87837-1-imp@bsdimp.com> (raw)
This series of patches brings in 32-bit arm support for bsd-user. It implements
all the bits needed to do image activation, signal handling, stack management
and threading. This allows us to get to the "Hello World" level. The arm and x86
code are now the same as in the bsd-user fork. For full context, the fork is at
https://github.com/qemu-bsd-user/qemu-bsd-user/tree/blitz (though the the recent
sig{bus,segv} needed updates are incomplete).
v4 changes the following:
* Remove mips* -- the bsd-user fork has removed it, so clean up the clutter.
* Move target_os_ucontext.h patch earlier in the series and add check of
ucontext_t and mcontext_t sizes to match native sizes.
* Move x86 patches earlier in the patch series and Fill in the i386 and
x86_64 mcontext contents to match FreeBSD and define
TARGET_[UM]CONTEXT_SIZE to enable size checking.
* generally: Move inlines from target_arch_signal.h to signal.c
* Collapse arm's definition mcontext and trapframe into one commit and
add size with TARGET_[MU]CONTEXT_SIZE.
* Fix the saving of vfp context to use proper locking and fetching
of target address to get/save it.
* Filter out low-order bits of pc in arm set_mcontext()
Where code just moved (maybe with trivial changes), I retained reviewed-by
tagging. When the changes were more substantial due to issues discovered
by getting the size right, I droppped prior review. The following thus
lack review:
bsd-user/mips*: Remove
bsd-user/freebsd: Create common target_os_ucontext.h file
bsd-user: create a per-arch signal.c file
bsd-user/i386/target_arch_signal.h: Update mcontext_t to match FreeBSD
bsd-user/i386: Move the inlines into signal.c
bsd-user/x86_64/target_arch_signal.h: Fill in mcontext_t
bsd-user/x86_64: Move functions into signal.c
bsd-user/arm/target_arch_signal.h: arm machine context and trapframe for signals
bsd-user/arm/target_arch_signal.h: Define size of *context_t
bsd-user/arm/target_arch_signal.c: arm get_mcontext
bsd-user/arm/target_arch_signal.c: arm set_mcontext
bsd-user/freebsd/target_os_ucontext.h: Require TARGET_*CONTEXT_SIZE
Warnings that should be ignored:
o make checkpatch has a couple of complaints about the comments for the
signal trampoline, since it's a false positive IMHO.
WARNING: Block comments use a leading /* on a separate line
+ /* 8 */ sys_sigreturn,
WARNING: Block comments use a leading /* on a separate line
+ /* 9 */ sys_exit
