This function is defined twice, one at cx25821-i2c and the other inside cx25821-core. It turns that only the first is actually used inside the code. This causes a clang warning. Signed-off-by: -

The G2 decoder block produces NV12 4x4 tiled format (NV12_4L4). Enable the G2 post-processor block, in order to produce regular NV12. The logic in hantro_postproc.c is leveraged to take care of allocating the extra buffers and configure the post-processor, which is significantly simpler than the one on the G1. Signed-off-by:

The G2 core decoder engine produces NV12_4L4 format, which is a simple NV12 4x4 tiled format. The driver currently hides this format by always enabling the post-processor engine, and therefore offering NV12 directly. This is done without using the logic in hantro_postproc.c and therefore makes it difficult to add VP9 cleanly. Since fixing this is not easy, add a small quirk to force NV12 if HEVC was configured, but otherwise declare NV12_4L4 as the pixel format in imx8mq_vpu_g2_variant.dec_fmts. This will be used by the VP9 decoder which will be added soon. Signed-off-by:

Turns out the post-processor block on the G2 core is substantially different from the one on the G1 core. Introduce hantro_postproc_ops with .enable and .disable methods, which will allow to support the G2 post-processor cleanly. Signed-off-by:

Ezequiel Garcia authored
When the post-processor hardware block is enabled, the driver allocates an internal queue of buffers for the decoder enginer, and uses the vb2 queue for the post-processor engine. For instance, on a G1 core, the decoder engine produces NV12 buffers and the post-processor engine can produce YUY2 buffers. The decoder engine expects motion vectors to be appended to the NV12 buffers, but this is only required for CODECs that need motion vectors, such as H.264. Fix the post-processor logic accordingly.

At connection time (or boot) in si2168_probe(), the firmware is not loaded to the device and the device is not fully activated. It is not useful or sensible to do this full initialization on resume in case it has not been previously initialized and is expected to be in this initialized state. Calling si2168_init() and therefore reading the firmware file for the first time during resume leads to problems and should be avoided. It is however safe to read the firmware file once it has already been read outside of a suspend/resume situation. Add a staus flag 'initialized' to store whether si2168_init() has successfully been called. If initialization fails (e.g. due to missing firmware file), the flag is not set. Register a separate si2168_resume callback which only calls si2168_init() once the 'initialized' flag has been set and it is safe to load the firmware at resume. The first call to si2168_init() will now always happen when the device is actually used for the first time and never during resume. This avoids the unsafe firmware file reading and should also speed up resume by skipping unnecessary device initialization.

The si2168 B40 firmware file name has been changed in or before 2014. During initialization, the new file name is preferred, but the old file name is used as a fallback when request_firmware with the new file name fails. Once reading the old file name has been attempted, only this name will be used on further firmware loading attempts. During resume, firmware reading with the new file name can (and likely will) fail even when it actually exists. So this permanent switch to the fallback firmware name happens even when not desired. Any system using a recent kernel version can be expected to have the firmware under the new name. The major distributions are either using the dvb firmware collection from LibreELEC, which has the new firmware file name, or do not package the firmware file but have documentation pointing towards a manual installation of the firmware file under the new name. If the firmware is available under the old name, it is severely outdated. If the switch to the old file name is performed, further firmware loading will either permanently fail (if it is not available) or an outdated firmware version will be used. Drop support for the fallback firmware file name and fail directly if the firmware is not available under its current name. On following attempts, the firmware read will then be retried with the correct current name instead of the old name. As reasoned above, there should be no negative effects of this change, while simplifying code (the B40 variant will be handled identical compared to the other variants of the si2168) and at the same time fixing possible problems if firmware loading fails on resume.

This fixes a problem where closing the tuner would leave it in a state where it would not tune to any channel when reopened. This problem was discovered as part of https://github.com/hselasky/webcamd/issues/16. Since adap->id is 0 or 1, this bit-shift overflows, which is undefined behavior. The driver still worked in practice as the overflow would in most environments result in 0, which rendered the line a no-op. When running the driver as part of webcamd however, the overflow could lead to 0xff due to optimizations by the compiler, which would, in the end, improperly shut down the tuner. The bug is a regression introduced in the commit referenced below. The present patch causes identical behavior to before that commit for adap->id equal to 0 or 1. The driver does not contain support for dib0700 devices with more adapters, assuming such even exist. Tests have been performed with the Xbox One Digital TV Tuner on amd64. Not all dib0700 devices are expected to be affected by the regression; this code path is only taken by those with incorrect endpoint numbers.

While dvb_tuner_ops already has dedicated suspend and resume callbacks, dvb_frontend_ops currently does not have them. Add those callbacks and use them for suspend and resume. If they are not set, the old behavior of calling sleep or init is used. This allows dvb_frontend drivers to handle resume differently from init, and suspend differently from sleep. No change is required for drivers not needing this functionality.

A out-of-bounds bug can be triggered by an interrupt, the reason for this bug is the lack of checking of register values. In flexcop_pci_isr, the driver reads value from a register and uses it as a dma address. Finally, this address will be passed to the count parameter of find_next_packet. If this value is larger than the size of dma, the index of buffer will be out-of-bounds. Fix this by adding a check after reading the value of the register. The following KASAN report reveals it: BUG: KASAN: slab-out-of-bounds in find_next_packet drivers/media/dvb-core/dvb_demux.c:528 [inline] BUG: KASAN: slab-out-of-bounds in _dvb_dmx_swfilter

USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ. Use the common control-message timeout define for the five-second timeouts.

USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ. Note that the driver was multiplying some of the timeout values with HZ twice resulting in 3000-second timeouts with HZ=1000. Also note that two of the timeout defines are currently unused.
