2022-02-17media: Define MIPI CSI-2 data types in a shared header fileLaurent Pinchart1-0/+45
There are many CSI-2-related drivers in the media subsystem that come with their own macros to handle the CSI-2 data types (or just hardcode the numerical values). Provide a shared header with definitions for those data types that driver can use.

2022-02-17media: vsp1: mask interrupts before enablingNikita Yushchenko1-8/+29
VSP hardware could be used (e.g. by the bootloader) before driver load, and some interrupts could be left in enabled and pending state. In this case, setting up VSP interrupt handler without masking interrupts before causes interrupt handler to be immediately called (and crash due to null vsp->info dereference). Fix that by explicitly masking all interrupts before setting the interrupt handler. To do so, have to set the interrupt handler later, after hw revision is already detected and number of interrupts to mask gets known. Based on patch by Koji Matsuoka <koji.matsuoka.xm@renesas.com> included in the Renesas BSP kernel.

In cal_ctx_v4l2_init_formats(), devm_kzalloc() is assigned to ctx->active_fmt and there is a dereference of it after that, which could lead to NULL pointer dereference on failure of devm_kzalloc(). Fix this bug by adding a NULL check of ctx->active_fmt. This bug was found by a static analyzer.

2022-02-17media: omap3isp: Use struct_group() for memcpy() regionKees Cook2-10/+16
In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Wrap the target region in struct_group(). This additionally fixes a theoretical misalignment of the copy (since the size of "buf" changes between 64-bit and 32-bit, but this is likely never built for 64-bit). FWIW, I think this code is totally broken on 64-bit (which appears to not be a "real" build configuration): it would either always fail (with an uninitialized data->buf_size) or would cause corruption in userspace due to the copy_to_user() in the call path against an uninitialized data->buf value: omap3isp_stat_request_statistics_time32(...) struct omap3isp_stat_data data64; ... omap3isp_stat_request_statistics(stat, &data64); int omap3isp_stat_request_statistics(struct ispstat *stat, struct omap3isp_stat_data *data) ... buf = isp_stat_buf_get(stat, data); static struct ispstat_buffer *isp_stat_buf_get(struct ispstat *stat, struct omap3isp_stat_data *data) ... if (buf->buf_size > data->buf_size) { ... return ERR_PTR(-EINVAL); } ... rval = copy_to_user(data->buf, buf->virt_addr, buf->buf_size); Regardless, additionally initialize data64 to be zero-filled to avoid undefined behavior.

2022-02-17ALSA: hda/hdmi: add keep-alive support for ADL-P and DG2Kai Vehmanen2-49/+126
Implement HDA keep alive (KAE) support for Intel display codecs. When no audio stream is active, the display codec will provide a continuous clock and a valid but silent audio stream to any connected HDMI/DP receiver. Without this, upon starting a new playback stream, initial samples may be lost as many receivers require time to initialize for new clock. This is a new feature in Intel AlderLake-P display codec implementation and replaces the Intel i915 silent-stream extension that has been used on older hardware. Main benefit of the new method is that codec no longer needs to be kept in D0 power state. This patch depends on commit 112a87c48e83 ("drm/i915/display: program audio CDCLK-TS for keepalives").

Introduce mlx5e_tc_post_act_offload() and mlx5e_tc_post_act_unoffload() to be able to unoffload and reoffload existing post action rules handles. For example in neigh update events, the driver removes and readds rules in hardware. Signed-off-by: Roi Dayan <roid@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2022-02-16net/mlx5e: Pass actions param to actions_match_supported()Roi Dayan2-3/+8
Currently the mlx5_flow object contains a single mlx5_attr instance. However, multi table actions (e.g. CT) instantiate multiple attr instances. Currently action_match_supported() reads the actions flag from the flow's attribute instance. Modify the function to receive the action flags as a parameter which is set by the calling function and pass the aggregated actions to actions_match_supported().

2022-02-16net/mlx5e: RX, Restrict bulk size for small Striding RQsTariq Toukan5-2/+10
In RQs of type multi-packet WQE (Striding RQ), each WQE is relatively large (typically 256KB) but their number is relatively small (8 in default). Re-mapping the descriptors' buffers before re-posting them is done via UMR (User-Mode Memory Registration) operations. On the one hand, posting UMR WQEs in bulks reduces communication overhead with the HW and better utilizes its processing units. On the other hand, delaying the WQE repost operations for a small RQ (say, of 4 WQEs) might drastically hit its performance, causing packet drops due to no receive buffer, for high or bursty incoming packets rate. Here we restrict the bulk size for too small RQs. Effectively, with the current constants, RQ of size 4 (minimum allowed) would have no bulking, while larger RQs will continue working with bulks of 2.

2022-02-16net/mlx5e: Default to Striding RQ when not conflicting with CQE compressionTariq Toukan1-2/+3
CQE compression is turned on by default on slow pci systems to help reduce the load on pci. In this case, Striding RQ was turned off as CQEs of packets that span several strides were not compressed, significantly reducing the compression effectiveness. This issue does not exist when using the newer mini_cqe format "stride_index". Hence, allow defaulting to Striding RQ in this case.
