Subject: [PATCH v1 0/4] introduce generic implementation of macros from bug.h
Date: Fri, 3 Feb 2023 19:05:46 +0200 [thread overview]
Message-ID: <cover.1675441720.git.oleksii.kurochko@gmail.com> (raw)
A large part of the content of the bug.h is repeated among all
architectures (especially ARM and RISCV have the same implementation), so it
was created a new config CONFIG_GENERIC_BUG_FRAME which are used to
introduce generic implementation of do_bug_frame() and move ARM's <asm/bug.h>
to <xen/common/...> with the following changes:
* add inclusion of arch-specific header <asm/bug.h>
* rename the guard and remove ARM specific changes
* wrap macros BUG_FRAME/run_in_exception_handler/WARN/BUG/assert_failed
into #ifndef "BUG_FRAME/run_in_exception_handler/WARN/BUG/assert_failed"
thereby each architecture can override generic implementation of macros.
* add #ifdef __ASSEMBLY__ ... #endif
* Update run_in_exception_handler() with:
register void *fn_ asm(__stringify(BUG_FN_REG)) = (fn);
to avoid:
asm ("mv " __stringify(BUG_FN_REG) ", %0\n"
For x86 only common parts was removed from <asm/bug.h>.
RISC-V will be switched to use <xen/bug.h> and in the future, it will use common
the version of do_bug_frame() when xen/common will work for RISC-V.
Oleksii Kurochko (4):
xen: introduce CONFIG_GENERIC_BUG_FRAME
xen/arm: switch ARM to use generic implementation of bug.h
xen/x86: switch x86 to use generic implemetation of bug.h
xen: change <asm/bug.h> to <xen/bug.h>
