* video: tegra: nvmap: Fix race between write and freeAshish Mhetre2022-01-11
| | | | | | | | | | | | | | | | | | | | | | When NvRmMemWrite() and NvRmMemFree() are called simultaneously on same handle then it could lead to race where dmabuf freed from NvRmMemFree() call could get used by nvmap_get_cachebility() and cause kernel crash. When dmabuf is freed, its exported functions such as get_drvdata() won't be valid anymore and will give error value or NULL. Fix this by checking if get_drvdata() returns error value or NULL and act accordingly.

Hence we can simplify the capture thread to program only the capture released settings, skip the checking of SOF and leave the checking of vi/csi status and the recovery process to be done in the release thread. Also simplify vi2_channel_stop_streaming() to not invoke tegra_channel_capture_done() as the buffers shall be well handled in tegra_channel_queued_buf_done() with VB2_BUF_STATE_ERROR state. In the original implementation, chan->syncpt[index][] will be re-allocated for every single stop_streaming()/start_streaming() pair, so the syncpt IDs may change. This is causing the problem: the syncpt IDs armed for the previous failing capture are still queued in the FIFO and will be used for the next successfull frame capture, however new syncpt IDs are allocated for the new coming frames, e.g, the below error prints: 2021-11-23T08:12:59.038+00:00 kernel: [ 590.029312] tegra_channel_capture_frame_multi_thread[570]: rv 4, cv 3, stm Y 2021-11-23T08:12:59.038+00:00 kernel: [ 590.036865] tegra_channel_enable_stream[212] -- begin 2021-11-23T08:12:59.044+00:00 kernel: [ 590.042437] tegra_channel_enable_stream[221] -- end 2021-11-23T08:12:59.263+00:00 kernel: [ 590.251676] video4linux video0: frame start syncpt timeout!0 2021-11-23T08:12:59.263+00:00 kernel: [ 590.257419] tegra_channel_ec_recover[337] -- begin 2021-12-03T11:14:36.763+00:00 kernel: [ 1049.109289] vi2_channel_start_streaming[912] -- begin 2021-12-03T11:14:36.763+00:00 kernel: [ 1049.115121] vi2_channel_start_streaming[949]: syncpt id 24, max 5064, min 5064 2021-12-03T11:14:36.771+00:00 kernel: [ 1049.123116] vi2_channel_start_streaming[949]: syncpt id 28, max 1614, min 1614 --> the syncpt id being used for this streaming are 24/28, these two syncpts are used since the first streaming ... 2021-12-03T11:14:39.244+00:00 kernel: [ 1051.597885] tegra_channel_capture_frame_multi_thread[624] -- end: release_thresh 5101 2021-12-03T11:14:39.303+00:00 kernel: [ 1051.663550] tegra_channel_release_frame[701] -- end: buf->thresh 5101 2021-12-03T11:14:39.350+00:00 kernel: [ 1051.703617] vi2_channel_stop_streaming[1065] -- end --> no problem observed, and capture cancelled due to stop_streaming ... 2021-12-03T11:15:09.524+00:00 kernel: [ 1081.871259] vi2_channel_start_streaming[912] -- begin 2021-12-03T11:15:09.524+00:00 kernel: [ 1081.876860] vi2_channel_start_streaming[949]: syncpt id 36, max 0, min 0 2021-12-03T11:15:09.524+00:00 kernel: [ 1081.884187] vi2_channel_start_streaming[949]: syncpt id 38, max 0, min 0 --> the syncpt id being used now are changed to 36/38 ... 2021-12-03T11:15:09.534+00:00 kernel: [ 1081.891728] tegra_channel_capture_frame_multi_thread[514] -- begin 2021-12-03T11:15:09.534+00:00 kernel: [ 1081.891771] vi2_channel_start_streaming[992] -- end 2021-12-03T11:15:09.552+00:00 kernel: [ 1081.904384] tegra_channel_capture_frame_multi_thread[569]: rv 119, cv 119, stm N 2021-12-03T11:15:09.606+00:00 kernel: [ 1081.958030] tegra_channel_capture_frame_multi_thread[624] -- end: release_thresh 1 2021-12-03T11:15:09.606+00:00 kernel: [ 1081.958086] tegra_channel_release_frame[669] -- begin 2021-12-03T11:15:09.817+00:00 kernel: [ 1082.162133] video4linux video0: tegra_channel_release_frame: MW_ACK_DONE syncpoint time out!0 2021-12-03T11:15:09.817+00:00 kernel: [ 1082.170683] tegra_channel_release_frame[680]: buf->thresh[0] 1 2021-12-03T11:15:09.817+00:00 kernel: [ 1082.176972] tegra_channel_release_frame[683]: syncpt 36, hw val 0 2021-12-03T11:15:09.829+00:00 kernel: [ 1082.183715] tegra_channel_ec_recover[337] -- begin Given Hw doesn't support SYNCPT FIFO reset per stream, reuse the same syncpt IDs until the channel is powered off.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: The len of buffers allocated is based on the MTU configured at the DUT. In case a Rx packet received is more than the MTU configured, then the packet appears in the ring with LD bit set which further gets processed even if the buffers length allocated is less than the received packet len. The frame hence consumes more than 1 rx desc and kfree for an skb with no LD bit set and neither error bits set got called causing kernel panic. Fix: Drops such pkts for which the configured MTU and received pkt len is different to avoid packects consuming more than 1 rx desc, and always accommodate single packet in single rx desc buffer.

* tegra-smmu: Fix grep in 12000000.iommu debugfs.Achal Verma2021-10-06
| | | | | | | | | | | | | | | | | | | | | | | | grep in /sys/kernel/debug/12000000.iommu/ failing because inside masters/ some devices didn't have pointers set for cfg, so added check in debugfs show for NULL pointer. And other issue is accessing registers inside gnsr dir. These registers are not ioremapped or access to them is not allowed in case of hypervisor. So removed gnsr node creation in hypervisor case.
