[ Upstream commit 163e5f2 ] When using perf record with the `--overwrite` option, a segmentation fault occurs if an event fails to open. For example: perf record -e cycles-ct -F 1000 -a --overwrite Error: cycles-ct:H: PMU Hardware doesn't support sampling/overflow-interrupts. Try 'perf stat' perf: Segmentation fault #0 0x6466b6 in dump_stack debug.c:366 #1 0x646729 in sighandler_dump_stack debug.c:378 #2 0x453fd1 in sigsegv_handler builtin-record.c:722 #3 0x7f8454e65090 in __restore_rt libc-2.32.so[54090] #4 0x6c5671 in __perf_event__synthesize_id_index synthetic-events.c:1862 #5 0x6c5ac0 in perf_event__synthesize_id_index synthetic-events.c:1943 #6 0x458090 in record__synthesize builtin-record.c:2075 #7 0x45a85a in __cmd_record builtin-record.c:2888 #8 0x45deb6 in cmd_record builtin-record.c:4374 #9 0x4e5e33 in run_builtin perf.c:349 #10 0x4e60bf in handle_internal_command perf.c:401 #11 0x4e6215 in run_argv perf.c:448 #12 0x4e653a in main perf.c:555 #13 0x7f8454e4fa72 in __libc_start_main libc-2.32.so[3ea72] #14 0x43a3ee in _start ??:0 The --overwrite option implies --tail-synthesize, which collects non-sample events reflecting the system status when recording finishes. However, when evsel opening fails (e.g., unsupported event 'cycles-ct'), session->evlist is not initialized and remains NULL. The code unconditionally calls record__synthesize() in the error path, which iterates through the NULL evlist pointer and causes a segfault. To fix it, move the record__synthesize() call inside the error check block, so it's only called when there was no error during recording, ensuring that evlist is properly initialized.

[ Upstream commit 2939203 ] In the current implementation, the enetc_xdp_xmit() always transmits redirected XDP frames even if the link is down, but the frames cannot be transmitted from TX BD rings when the link is down, so the frames are still kept in the TX BD rings. If the XDP program is uninstalled, users will see the following warning logs. fsl_enetc 0000:00:00.0 eno0: timeout for tx ring #6 clear More worse, the TX BD ring cannot work properly anymore, because the HW PIR and CIR are not equal after the re-initialization of the TX BD ring. At this point, the BDs between CIR and PIR are invalid, which will cause a hardware malfunction. Another reason is that there is internal context in the ring prefetch logic that will retain the state from the first incarnation of the ring and continue prefetching from the stale location when we re-initialize the ring. The internal context is only reset by an FLR. That is to say, for LS1028A ENETC, software cannot set the HW CIR and PIR when initializing the TX BD ring. It does not make sense to transmit redirected XDP frames when the link is down. Add a link status check to prevent transmission in this condition. This fixes part of the issue, but more complex cases remain. For example, the TX BD ring may still contain unsent frames when the link goes down. Those situations require additional patches, which will build on this one.

commit c943bfc upstream. After a copy pair swap the block device's "device" symlink points to the secondary CCW device, but the gendisk's parent remained the primary, leaving /sys/block/<dasdx> under the wrong parent. Move the gendisk to the secondary's device with device_move(), keeping the sysfs topology consistent after the swap.

Disable all display related hardware blocks on biscuit as they are unused. Also disable the Mali GPU as it seems to either be fused off or not present on the MT8163 variant used on biscuit. This is done in a new mt8163-headless.dtsi file so other headless MT8163 devices (should they exist) can include it in their device trees. Thermal is also disabled on biscuit specifically as the ADC sensors on aren't present. Signed-off-by: Ben Grisdale <bengris32@protonmail.ch>

The goodix driver allows the max_x and max_y properties to be overriden from the device tree so long as the read config from the touch controller is valid. If that is not the case however, then the driver will override max_x and max_y to default values regardless of whether they are actually valid or not. Fix this by checking again if max_x and max_y are invalid, and if so then set them to safe defaults, but otherwise, use the values parsed from the device tree.

The MediaTek MT8196 vlpckgen clock driver uses __devm_regmap_init_mmio_clk() by devm_regmap_init_mmio(), which is defined in drivers/base/regmap/regmap-mmio.c. However, the driver's Kconfig entry does not select REGMAP_MMIO. This causes a linker error when REGMAP_MMIO is not enabled. Fix this by selecting REGMAP_MMIO in the Kconfig entry.
