[PATCH v2 01/12] drm/panfrost: Make sure MMU context lifetime is not bound to panfrost_priv

by Boris Brezillon

Jobs can be in-flight when the file descriptor is closed (either because the process did not terminate properly, or because it didn't wait for all GPU jobs to be finished), and apparently panfrost_job_close() does not cancel already running jobs. Let's refcount the MMU context object so it's lifetime is no longer bound to the FD lifetime and running jobs can finish properly without generating spurious page faults.

[RFC 2/2] ARM: dts: imx6dl-yapp4: Fix lp5562 driver probe

by Michal Vokáč

Since the LED multicolor framework support was added in commit 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx") LEDs on this platform stopped working. Author of the framework attempted to accommodate this DT to the framework in commit b86d3d21cd4c ("ARM: dts: imx6dl-yapp4: Add reg property to the lp5562 channel node") but that is not sufficient. A color property is now required even if the multicolor framework is not used, otherwise the driver probe fails: lp5562: probe of 1-0030 failed with error -22 Add the color property to fix this and remove the actually unused white channel.

[RESEND PATCH 1/3] perf/x86/intel: Fix fixed counter check warning for some Alder Lake

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> For some Alder Lake machine, the below fixed counter check warning may be triggered. [ 2.010766] hw perf events fixed 5 > max(4), clipping! Current perf unconditionally increases the number of the GP counters and the fixed counters for a big core PMU on an Alder Lake system, because the number enumerated in the CPUID only reflects the common counters. The big core may has more counters. However, Alder Lake may have an alternative configuration. With that configuration, the X86_FEATURE_HYBRID_CPU is not set. The number of the GP counters and fixed counters enumerated in the CPUID is accurate. Perf mistakenly increases the number of counters. The warning is triggered. Directly use the enumerated value on the system with the alternative configuration.

[PATCH 2/3] perf/x86/intel: Add more events requires FRONTEND MSR on Sapphire Rapids

by kan.liang＠linux.intel.com

From: Kan Liang <kan.liang(a)linux.intel.com> On Sapphire Rapids, there are two more events 0x40ad and 0x04c2 which rely on the FRONTEND MSR. If the FRONTEND MSR is not set correctly, the count value is not correct. Update intel_spr_extra_regs[] to support them.

[PATCH 3/3] perf/x86/intel: Fix instructions:ppp support in Sapphire Rapids

[net 2/2] can: peak_pciefd: pucan_handle_status(): fix a potential starvation issue in TX path

by Marc Kleine-Budde

From: Stephane Grosjean <s.grosjean(a)peak-system.com> Rather than just indicating that transmission can start, this patch requires the explicit flushing of the network TX queue when the driver is informed by the device that it can transmit, next to its configuration. In this way, if frames have already been written by the application, they will actually be transmitted.
