powerpc: replace #include with #include

2023-08-16T13:54:48+00:00

Commit ddb5cdbafaaa ("kbuild: generate KSYMTAB entries by modpost") deprecated , which is now a wrapper of . Replace #include with #include . After all the lines are converted, and will be removed.

powerpc: add CFUNC assembly label annotation

2023-04-20T02:54:24+00:00

This macro is to be used in assembly where C functions are called. pcrel addressing mode requires branches to functions with a localentry value of 1 to have either a trailing nop or @notoc. This macro permits the latter without changing callers.

selftests/powerpc: Include asm/cputable.h from utils.h

2020-09-08T12:23:59+00:00

utils.h provides have_hwcap() and have_hwcap2() which check for a feature bit. Those bits are defined in asm/cputable.h, so include it in utils.h so users of utils.h don't have to do it manually.

selftests/powerpc: Skip vmx/vsx/tar/etc tests on older CPUs

2020-08-03T12:12:41+00:00

Some of our tests use VSX or newer VMX instructions, so need to be skipped on older CPUs to avoid SIGILL'ing. Similarly TAR was added in v2.07, and the PMU event used in the stcx fail test only works on Power8 or later.

selftests/powerpc: Add test of memcmp at end of page

2020-07-23T07:43:36+00:00

Update our memcmp selftest, to test the case where we're comparing up to the end of a page and the subsequent page is not mapped. We have to make sure we don't read off the end of the page and cause a fault. We had a bug there in the past, fixed in commit d9470757398a ("powerpc/64: Fix memcmp reading past the end of src/dest").

selftests/powerpc: Ignore generated files

2019-08-22T13:12:47+00:00

Currently some binary files which are generated when tests are compiled are not ignored by git, so 'git status' catch them. For copyloops test, fix wrong binary names already in .gitignore. For ptrace, security, and stringloops tests add missing binary names to the .gitignore file.

Pull powerpc updates from Michael Ellerman: "Notable changes: - Removal of the NPU DMA code, used by the out-of-tree Nvidia driver, as well as some other functions only used by drivers that haven't (yet?) made it upstream. - A fix for a bug in our handling of hardware watchpoints (eg. perf record -e mem: ...) which could lead to register corruption and kernel crashes. - Enable HAVE_ARCH_HUGE_VMAP, which allows us to use large pages for vmalloc when using the Radix MMU. - A large but incremental rewrite of our exception handling code to use gas macros rather than multiple levels of nested CPP macros. And the usual small fixes, cleanups and improvements.
