2023-11-20arm64/arm: arm_pmuv3: perf: Don't truncate 64-bit registersIlkka Koskinen1-3/+3
[ Upstream commit 403edfa436286b21f5ffe6856ae5b36396e8966c ] The driver used to truncate several 64-bit registers such as PMCEID[n] registers used to describe whether architectural and microarchitectural events in range 0x4000-0x401f exist. Due to discarding the bits, the driver made the events invisible, even if they existed. Moreover, PMCCFILTR and PMCR registers have additional bits in the upper 32 bits. This patch makes them available although they aren't currently used. Finally, functions handling PMXEVCNTR and PMXEVTYPER registers are removed as they not being used at all.

2023-11-20drm/syncobj: fix DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLEErik Kurzinger1-1/+2
[ Upstream commit 101c9f637efa1655f55876644d4439e552267527 ] If DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT is invoked with the DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE flag set but no fence has yet been submitted for the given timeline point the call will fail immediately with EINVAL. This does not match the intended behavior where the call should wait until the fence has been submitted (or the timeout expires). The following small example program illustrates the issue. It should wait for 5 seconds and then print ETIME, but instead it terminates right away after printing EINVAL. #include <stdio.h> #include <fcntl.h> #include <time.h> #include <errno.h> #include <xf86drm.h> int main(void) { int fd = open("/dev/dri/card0", O_RDWR); uint32_t syncobj; drmSyncobjCreate(fd, 0, &syncobj); struct timespec ts; clock_gettime(CLOCK_MONOTONIC, &ts); uint64_t point = 1; if (drmSyncobjTimelineWait(fd, &syncobj, &point, 1, ts.tv_sec * 1000000000 + ts.tv_nsec + 5000000000, // 5s DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE, NULL)) { printf("drmSyncobjTimelineWait failed %d\n", errno); } } Fixes: 01d6c3578379 ("drm/syncobj: add support for timeline point wait v8") Signed-off-by: Erik Kurzinger <ekurzinger@nvidia.com> Reviewed by: Simon Ser <contact@emersion.fd> Signed-off-by: Simon Ser <contact@emersion.fr> Link: https://patchwork.freedesktop.org/patch/msgid/1fac96f1-2f3f-f9f9-4eb0-340f27a8f6c0@nvidia.com Signed-off-by: Sasha Levin <sashal@kernel.org>

NETLINK_MAX_FMTMSG_LEN [ Upstream commit f968c56417f00be4cb62eadeed042a1e3c80dc53 ] NETLINK_MAX_FMTMSG_LEN is currently hardcoded to 80, and we provide an error printf-formatted string having 96 characters including the terminating \0. Assuming each %d (representing a queue) gets replaced by a number having at most 2 digits (a reasonable assumption), the final string is also 96 characters wide, which is too much. Reduce the verbiage a bit by removing some (partially) redundant words, which makes the new printf-formatted string be 73 characters wide with the trailing newline.

[ Upstream commit db456d90a4c1b43b6251fa4348c8adc59b583274 ] From XGMAC Core 3.20 and later, each Flexible PPS has individual PPSEN bit to select Fixed mode or Flexible mode. The PPSEN must be set, or it stays in Fixed PPS mode by default. XGMAC Core prior 3.20, only PPSEN0(bit 4) is writable. PPSEN{1,2,3} are read-only reserved, and they are already in Flexible mode by default, our new code always set PPSEN{1,2,3} do not make things worse ;-) Fixes: 95eaf3cd0a90 ("net: stmmac: dwxgmac: Add Flexible PPS support") Reviewed-by: Serge Semin <fancer.lancer@gmail.com> Reviewed-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: Furong Xu <0x1207@gmail.com> Signed-off-by: David S.

[ Upstream commit 2d6812b41e0d832919d72c72ebddf361df53ba1b ] Instead of using one allocation per capture channel, use a single one. Also store it in driver data instead of chip data. This has several advantages: - driver data isn't cleared when pwm_put() is called - Reduces memory fragmentation Also register the pwm chip only after the per capture channel data is initialized as the capture callback relies on this initialization and it might be called even before pwmchip_add() returns. It would be still better to have struct sti_pwm_compat_data and the per-channel data struct sti_cpt_ddata in a single memory chunk, but that's not easily possible because the number of capture channels isn't known yet when the driver data struct is allocated.

[ Upstream commit 1fd6eb12642e0c32692924ff359c07de4b781d78 ] Add check for the return value of kstrdup() and return the error if it fails in order to avoid NULL pointer dereference. Moreover, use kfree() in the later error handling in order to avoid memory leak.

[ Upstream commit 61334819aca018c3416ee6c330a08a49c1524fc3 ] s3c_camif_register_video_node() works with video_device structure stored as a field of camif_vp, so it should not be kfreed. But there is video_device_release() on error path that do it. Found by Linux Verification Center (linuxtesting.org) with SVACE.

[ Upstream commit 0aeccc63f3bc4cfd49dc4893da1409402ee6b295 ] The driver uses the upper-bound approach to decide the target JPEG encode quality, but there's a logic bug that if the desired quality is higher than what the driver can support, the driver falls back to using the worst quality. Fix the bug by assuming using the best quality in the beginning, and with trivial refactor to avoid long lines.

[ Upstream commit bd5b50b329e850d467e7bcc07b2b6bde3752fbda ] There may be some a race condition between timer function bttv_irq_timeout and bttv_remove. The timer is setup in probe and there is no timer_delete operation in remove function. When it hit kfree btv, the function might still be invoked, which will cause use after free bug. This bug is found by static analysis, it may be false positive. Fix it by adding del_timer_sync invoking to the remove function. cpu0 cpu1 bttv_probe ->timer_setup ->bttv_set_dma ->mod_timer; bttv_remove ->kfree(btv); ->bttv_irq_timeout ->USE btv Fixes: 162e6376ac58 ("media: pci: Convert timers to use timer_setup()") Signed-off-by: Zheng Wang <zyytlz.wz@163.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Sasha Levin <sashal@kernel.org>
