[RFC PATCH v1 0/2] KVM: arm64: Making BT Field in ID_AA64PFR1_EL1 writable

by Shaoqin Huang

Hi guys, I'm trying to enable migration from MtCollins(Ampere Altra, ARMv8.2+) to AmpereOne(AmpereOne, ARMv8.6+), the migration always fails when migration from MtCollins to AmpereOne due to some register fields differing between the two machines. In this patch series, we try to make more register fields writable like ID_AA64PFR1_EL1.BT. This is first step towards making the migration possible. Some other hurdles need to be overcome. This is not sufficient to make the migration successful from MtCollins to AmpereOne. Shaoqin Huang (2): KVM: arm64: Allow BT field in ID_AA64PFR1_EL1 writable KVM: selftests: aarch64: Add writable test for ID_AA64PFR1_EL1 arch/arm64/kvm/sys_regs.c | 2 +- tools/testing/selftests/kvm/aarch64/set_id_regs.c | 6 ++++++ 2 files changed, 7 insertions(+), 1 deletion(-) -- 2.40.1

[PATCH] selftests/mm:fix test_prctl_fork_exec return failure

by aigourensheng

after calling fork() in the test_prctl_fork_exec() function, the global variable ksm_full_scans_fd is initialized to 0 in the child process upon entering the main function of ./ksm_functional_tests. In the function call chain test_child_ksm() -> __mmap_and_merge_range -> ksm_merge-> ksm_get_full_scans, start_scans = ksm_get_full_scans() will return an error. Therefore, the value of ksm_full_scans_fd needs to be initialized before calling test_child_ksm in the child process.

[PATCH v3 0/6] ALSA: some driver fixes for control input validations

by Takashi Iwai

Hi, this is a v3 patch set as a follow up of the thread about the errors reported by kselftest mixer-test. It changes HD-audio and vmaster control behavior to return -EINVAL for invalid input values. There is a change in kselftest itself to skip the verification after write tests for volatile controls, too. It's for the channel map controls that can't hold the stable values. v2->v3: * Replace with Mark's patch for kselftest * Apply the validation for user controls in put callback instead v1->v2: * Skip only verification after write in kselftest * Add sanity check to HDMI chmap write, too v2: https://lore.kernel.org/r/20240614153717.30143-1-tiwai@suse.de v1: https://lore.kernel.org/r/20240614124728.27901-1-tiwai@suse.de Takashi === Mark Brown (1): kselftest/alsa: Fix validation of writes to volatile controls Takashi Iwai (5): ALSA: vmaster: Return error for invalid input values ALSA: hda: Return -EINVAL for invalid volume/switch inputs ALSA: control: Apply sanity check of input values for user elements ALSA: chmap: Mark Channel Map controls as volatile ALSA: hda: Add input value sanity checks to HDMI channel map controls sound/core/control.c | 6 ++- sound/core/pcm_lib.c | 1 + sound/core/vmaster.c | 8 ++++ sound/hda/hdmi_chmap.c | 18 +++++++++ sound/pci/hda/hda_codec.c | 23 +++++++++--- tools/testing/selftests/alsa/mixer-test.c | 45 +++++++++++++++-------- 6 files changed, 79 insertions(+), 22 deletions(-) -- 2.43.0

[PATCH] kselftest/alsa: Fix validation of writes to volatile controls

by Mark Brown

When validating writes to controls we check that whatever value we wrote actually appears in the control. For volatile controls we cannot assume that this will be the case, the value may be changed at any time including between our write and read. Handle this by moving the check for volatile controls that we currently do for events to a separate block and just verifying that whatever value we read is valid for the control.
