kunit: qemu_configs: loongarch: Enable shutdown

2024-11-19T22:26:30Z

QEMU for LoongArch does not yet support shutdown/restart through ACPI. Use the pvpanic driver to enable shutdowns. This requires 9.1.0 for shutdown support in pvpanic, but that is the requirement of kunit on LoongArch anyways.

kunit: tool: Allow overriding the shutdown mode from qemu config

2024-11-19T22:26:30Z

Not all platforms support machine reboot. If it a proper reboot is not supported the machine will hang. Allow the QEMU configuration to override the necessary shutdown mode for the specific system under test.

kunit: qemu_configs: Add LoongArch config

2024-11-19T22:26:30Z

Add a basic config to run kunit tests on LoongArch. This requires QEMU 9.1.0 or later for the necessary direct kernel boot support.

kunit: tool: print failed tests only

2024-11-19T21:52:17Z

Add flag --failed to kunit.py to print only failed tests. This printing is done after running is over. This patch also adds the method print_test() that will also print your Test object. Before, all printing of tests occurred during parsing. This method could be useful in the future when converting to/from KTAP to this pretty-print output.

kunit: tool: Only print the summary

2024-11-19T21:52:17Z

Allow only printing the summary at the end of a test run, rather than all individual test results. This summary will list a few failing tests if there are any.

kunit: tool: Build compile_commands.json

2024-09-12T15:52:36Z

compile_commands.json is used by clangd[1] to provide code navigation and completion functionality to editors. See [2] for an example configuration that includes this functionality for VSCode. It can currently be built manually when using kunit.py, by running: ./scripts/clang-tools/gen_compile_commands.py -d .kunit With this change however, it's built automatically so you don't need to manually keep it up to date. Unlike the manual approach, having make build the compile_commands.json means that it appears in the build output tree instead of at the root of the source tree, so you'll need to add --compile-commands-dir=.kunit to your clangd args for it to be found. This might turn out to be pretty annoying, I'm not sure yet. If so maybe we can later add some hackery to kunit.py to work around it.

Merge tag 'riscv-config-for-v6.10' of https://git.kernel.org/pub/scm/linux/kernel/git/conor/linux into soc/drivers

2024-05-07T09:02:56Z

RISC-V SoC Kconfig Updates for v6.10 A few different bits of SoC-related Kconfig work. The first part of this is shared with the DT updates - the modification of all SOC_CANAAN users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away from the k230 that is able to be used in a "common" kernel. The other thing here is the removal of most of the SOC_VENDOR options, with their ARCH_VENDOR equivalents that've been waiting in the wings for 1 year+ now made visible. Due a lapse on my part when originally adding the ARCH_VENDOR stuff, the Microchip transition isn't complete - the _POLARFIRE was a mistake to keep as there's gonna be non-PolarFire RISC-V stuff from Microchip soonTM.

RISC-V: drop SOC_VIRT for ARCH_VIRT

2024-04-10T10:37:50Z

The ARCH_ and SOC_ versions of this symbol have persisted for quite a while now in parallel. Generated .config files from previous LTS kernels should have both. Finally remove SOC_VIRT and update all config files using it. Acked-by: Palmer Dabbelt Signed-off-by: Conor Dooley
