The DocBook documentation is incorrect: on ISDB-T, interleaving time is always a power of 2. Fix it and provides a table showing the actual interleaving length for each mode. Signed-off-by:Mauro Carvalho Chehab <m.chehab@samsung.com>

The programmed frequency on xc4000 is not the middle frequency, but the initial frequency on the bandwidth range. However, the DVB API works with the middle frequency. This works fine on set_frontend, as the device calculates the needed offset. However, at get_frequency(), the returned value is the initial frequency. That's generally not a big problem on most drivers, however, starting with changeset 6fe1099c, the frequency drift is taken into account at dib7000p driver. This broke support for PCTV 340e, with uses dib7000p demod and xc4000 tuner. Cc: stable@vger.kernel.org Signed-off-by:

The firmware name at: http://www.kernellabs.com/firmware/xc4000/ Is different from the one at the Kernel. Update it try first the new name, falling back to the previous one if the new name can't be found. Signed-off-by:

This patch removes the null test on ch. ch is initialized at the beginning of the function to &demod->dtv_property_cache. Since demod is dereferenced prior to the null test, demod must be a valid pointer, and &demod->dtv_property_cache cannot be null. The following Coccinelle script is used for detecting the change: @r@ expression e,f; identifier g,y; statement S1,S2; @@ *e = &f->g <+... f->y ...+> *if (e != NULL || ...) S1 else S2 Signed-off-by:

Interleaving code was wrong at mb86a20s: instead, it was looking at the Guard Interval. Fix it. Signed-off-by: -

The driver was reporting an incorrect mode, when mode 2 is selected. While testing it, noticed that neither mode 1 or guard interval 1/32 is supported by this device. Document it, and ensure that it will report _AUTO when it doesn't lock, in order to not report a wrong detection to userspace. Signed-off-by: -

This removes checks of struct member addresses since they likely result in the condition always being true. Also in the stb6100_get_bandwidth and tda8261_get_bandwidth functions the pointers frontend_ops and tuner_ops are assigned the same addresses twice. Signed-off-by:

This updated patch also fixes out of bound access to b[]. In dib9000_risc_apb_access_write() an out of bound access to mb[]. The current test to avoid out of bound access to mb[] is insufficient. For len = 19 non-existent mb[10] will be accessed. For odd values of len b[] is accessed out of bounds. For large values of len an of bound access to mb[] may occur in dib9000_mbx_send_attr.

This patch exports all auxiliary buffers, including SRAM, as debugfs binary blobs for debugging purposes. It shows, for example, that psbuf currently doesn't seem to be used at all on CODA7541, and that slicebuf and workbuf usage is far from the maximum. It can also be used to validate SRAM size allocation. Signed-off-by:

When encoding into h.264, the input frame stride needs to be a multiple of 16. During allocation of the input buffers, it may not be known yet whether the encoder should create h.264 or not. Assume the worst and always use a frame stride that is a multiple of 16. Signed-off-by:

CODA7541 only supports encoding h.264 frames with width and height that are multiples of the macroblock size. Signed-off-by:
-
Philipp Zabel authored
Even though the CODA h.264 decoder always decodes complete macroblocks, we can set the stride to the corresponding multiple of 16 and use a value smaller than that as real width. Unfortunately the same doesn't work for height, as there is no vertical linesperframe stride for discontiguous planar YUV frames. Signed-off-by:

Rename the per-context prescan_failed variable to hold, as this is what the flag does: it temporarily keeps the coda from running until new data is fed into the bitstream buffer or stop_streaming is called on the input side. A prescan failure on i.MX5 is one possible reason to enter this state, another one is a picture run timeout on i.MX6. Signed-off-by:

The coda h.264 decoder also counts PIC_RUNs where no frame was decoded but a frame was rotated out / marked as ready to be displayed. This causes an offset between the incoming encoded frame's sequence number and the decode sequence number returned by the coda. This patch introduces a sequence counter offset variable to keep track of the difference. Signed-off-by:

The coda driver advertises timestamp_type V4L2_BUF_FLAG_TIMESTAMP_COPY on both queues, so we have to copy timestamps from input v4l2 buffers to the corresponding destination v4l2 buffers. Since the h.264 decoder can reorder frames, a timestamp queue is needed to keep track of and assign the correct timestamp to destination buffers. Signed-off-by:
