There is not guarantee that this is true even after commit bcb7ee79029d ("posix-timers: Prefer delivery of signals to the current thread") because that commit only avoids waking up the sleeping process leader thread, but that has nothing to do with the actual signal delivery. As the signal is process wide the first thread which observes sigpending and wins the race to lock sighand will deliver the signal. Testing shows that this hangs on a regular base because some threads never win the race. The comment "This primarily tests that the kernel does not favour any one." is wrong. The kernel does favour a thread which hits the timer interrupt when CLOCK_PROCESS_CPUTIME_ID expires. Rewrite the test so it only checks that the group leader sleeping in join() never receives SIGALRM and the thread which burns CPU cycles receives all signals. In older kernels which do not have commit bcb7ee79029d ("posix-timers: Prefer delivery of signals to the current thread") the test-case fails immediately, the very 1st tick wakes the leader up. Otherwise it quickly succeeds after 100 ticks. CI testing wants to use newer selftest versions on stable kernels. In this case the test is guaranteed to fail. So check in the failure case whether the kernel version is less than v6.3 and skip the test result in that case.

[PATCH v4] soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request

by Maulik Shah

Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned addresses associated with it. These control voltage, enable state, mode, and in legacy targets, voltage headroom. The current in-flight request checking logic looks for exact address matches. Requests for different addresses of the same RPMh resource as thus not detected as in-flight. Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight request check for VRM requests by ignoring the address offset. This ensures that only one request is allowed to be in-flight for a given VRM resource. This is needed to avoid scenarios where request commands are carried out by RPMh hardware out-of-order leading to LDO regulator over-current protection triggering.

[PATCH 4/4] binder: fix max_thread type inconsistency

by Carlos Llamas

The type defined for the BINDER_SET_MAX_THREADS ioctl was changed from size_t to __u32 in order to avoid incompatibility issues between 32 and 64-bit kernels. However, the internal types used to copy from user and store the value were never updated. Use u32 to fix the inconsistency.

[PATCH v3 1/2] arm64: dts: qcom: sa8155p-adp: fix SDHC2 CD pin configuration

by Volodymyr Babchuk

There are two issues with SDHC2 configuration for SA8155P-ADP, which prevent use of SDHC2 and causes issues with ethernet: - Card Detect pin for SHDC2 on SA8155P-ADP is connected to gpio4 of PMM8155AU_1, not to SoC itself. SoC's gpio4 is used for DWMAC TX. If sdhc driver probes after dwmac driver, it reconfigures gpio4 and this breaks Ethernet MAC. - pinctrl configuration mentions gpio96 as CD pin. It seems it was copied from some SM8150 example, because as mentioned above, correct CD pin is gpio4 on PMM8155AU_1. This patch fixes both mentioned issues by providing correct pin handle and pinctrl configuration.

Apparently, the CPU is overheated

by Victor Porton

Since some version of Linux (I think since some 5.x), my computer started to turn off randomly, especially when under a load. A workaround is to put it into power saving mode (using Power in Gnome Settings). This makes it almost 2 times slower. Unmodified Asus X515EA. I recently updated BIOS to Asus's version 315, but this didn't help. Previously we cleared it from dust and replaced the thermal paste, but that didn't fix the problem. I am attaching dmidecode. In my previous email, I forgot to tell Linux version: $ uname -a Linux victor 6.5.0-28-generic #29-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar 28 23:46:48 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

Extend Framework 13 quirk

by Mario Limonciello

Hi, The Framework 13 quirk for s2idle got extended to cover another BIOS version very recently. Can you please backport this to 6.6.y and later as well? f609e7b1b49e ("platform/x86/amd/pmc: Extend Framework 13 quirk to more BIOSes") Thanks,
