kselftest/arm64: Fix output formatting for za-fork

2023-12-03T06:33:06+00:00

commit 460e462d22542adfafd8a5bc979437df73f1cbf3 upstream. The za-fork test does not output a newline when reporting the result of the one test it runs, causing the counts printed by kselftest to be included in the test name. Add the newline.

kselftest/arm64: Fix hwcaps selftest build

2023-08-18T16:07:44+00:00

The hwcaps selftest currently relies on the assembler being able to assemble the crc32w instruction but this is not in the base v8.0 so is not accepted by the standard GCC configurations used by many distributions. Switch to manually encoding to fix the build.

kselftest/arm64: add jscvt feature to hwcap test

2023-08-16T14:24:01+00:00

Add the jscvt feature check in the set of hwcap tests. Due to the requirement of jscvt feature, a compiler configuration of v8.3 or above is needed to support assembly. Therefore, hand encode is used here instead. Signed-off-by: Zeng Heng Reviewed-by: Mark Brown Link: https://lore.kernel.org/r/20230815040915.3966955-5-zengheng4@huawei.com Signed-off-by: Will Deacon

kselftest/arm64: build BTI tests in output directory

2023-08-16T13:43:47+00:00

The arm64 BTI selftests are currently built in the source directory, then the generated binaries are copied to the output directory. This leaves the object files around in a potentially otherwise pristine source tree, tainting it for out-of-tree kernel builds. Prepend $(OUTPUT) to every reference to an object file in the Makefile, and remove the extra handling and copying. This puts all generated files under the output directory.

kselftest/arm64: Size sycall-abi buffers for the actual maximum VL

2023-08-11T11:24:51+00:00

Our ABI opts to provide future proofing by defining a much larger SVE_VQ_MAX than the architecture actually supports. Since we use this define to control the size of our vector data buffers this results in a lot of overhead when we initialise which can be a very noticable problem in emulation, we fill buffers that are orders of magnitude larger than we will ever actually use even with virtual platforms that provide the full range of architecturally supported vector lengths. Define and use the actual architecture maximum to mitigate this.
