2020-11-26media: vidtv: simplify PSI write functionMauro Carvalho Chehab1-67/+63
The function vidtv_psi_ts_psi_write_into() initializes the ts_header fields several times, and receives a struct as argument, instead of using a pointer to struct. Cleanup the function, in order to reduce its stack usage and to avoid initializing the ts_header multiple times. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-11-26media: vidtv: add date to the current eventMauro Carvalho Chehab1-3/+41

2020-11-26media: vidtv: add a PID entry for the NIT tableMauro Carvalho Chehab4-17/+39

2020-11-26media: vidtv: properly fill EIT service_idMauro Carvalho Chehab3-4/+7
The EIT header ID field should not contain the network ID, but, instead, the service_id of the program described at EIT. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-11-26media: vidtv: fix the network ID rangeMauro Carvalho Chehab2-2/+2
As defined at ETSI TS 101 162, original network IDs up to 0xfebf are reserved for registration at dvb.org. Let's use, instead, an original network ID at the range 0xff00-0xffff, as this is for private temporary usage. As the same value is also used for the network ID, the range 0xff01-0xffff also fits better, as values lower than that depend if the network is used for satellite, terrestrial, cable of CI. While here, move the TS ID to the bridge code, where it is used, and change its value, as it was identical to the value previously used by network ID. While we could keep the same value, let's change it, just to make easier to check for the new code while reading it with DVB tools like dvbinspector.

2020-11-26media: vidtv: do some cleanups at the driverMauro Carvalho Chehab7-191/+182

2020-11-26media: vidtv: avoid copying data for PES structsMauro Carvalho Chehab3-108/+102
Minimize the number of data copies and initialization at the code, passing them as pointers instead of duplicating the data. The only case where we're keeping the data copy is at vidtv_pes_write_h(), as it needs a copy of the passed arguments. On such case, we're being more explicit.

2020-11-26media: vidtv: fix some notes at the tone generatorMauro Carvalho Chehab1-18/+20
The sheet music used to generate the tones had a few polyphonic notes. Due to that, its conversion to a tones sequence had a few errors. Also, due to a bug at the tone generator, it was missing the pause at the initial compass. Fix them. While here, reduce the compass to 100bpm. The music was converted from a Music XML file using this small script: <snip> my $count = 0; my $silent = 0; my $note; my $octave; print "\t"; while (<>) { $note = $1 if (m,\<step\>(.*)\</step\>,); $octave = "_$1" if (m,\<octave\>(.*)\</octave\>,); if (m,\<alter\>1\</alter\>,) { $note .= "S"; $sharp = 1; } if (m,\<rest/\>,) { $note = "SILENT"; $silent = 1; } if (m,\<duration\>(.*)\</duration\>,) { printf "{ NOTE_${note}${octave}, %d},", $1 * 128 / 480; $count++; if ($silent || $count >= 3) { print "\n\t"; $count = 0; $silent = 0; } else { print " "; print " " if (!$sharp); } $sharp = 0; $note = ""; $octave = ""; }; }; print "\n"; </snip> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-11-26media: vidtv: fix the tone generator logicMauro Carvalho Chehab2-11/+5

2020-11-26media: vidtv: don't use recursive functionsMauro Carvalho Chehab1-34/+41
The Linux stack is too short. So, using recursive functions is a very bad idea. Convert those into non-recursive ones. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-11-26media: vidtv: add error checksMauro Carvalho Chehab6-67/+289
Currently, there are not checks if something gets bad during memory allocation: it will simply use NULL pointers and crash. Add error path at the logic which allocates memory for the MPEG-TS generator code, propagating the errors up to the vidtv_bridge. Now, if something wents bad, start_streaming will return an error that userspace can detect: ERROR DMX_SET_PES_FILTER failed (PID = 0x2000): 12 Cannot allocate memory and the driver doesn't crash.

2020-11-05media: mtk-vcodec: fix build breakage when one of VPU or SCP is enabledAlexandre Courbot3-9/+47
The addition of MT8183 support added a dependency on the SCP remoteproc module. However the initial patch used the "select" Kconfig directive, which may result in the SCP module to not be compiled if remoteproc was disabled. In such a case, mtk-vcodec would try to link against non-existent SCP symbols. "select" was clearly misused here as explained in kconfig-language.txt. Replace this by a "depends" directive on at least one of the VPU and SCP modules, to allow the driver to be compiled as long as one of these is enabled, and adapt the code to support this new scenario. Also adapt the Kconfig text to explain the extra requirements for MT8173 and MT8183.

Pull drm updates from Dave Airlie: "Not a major amount of change, the i915 trees got split into display and gt trees to better facilitate higher level review, and there's a major refactoring of i915 GEM locking to use more core kernel concepts (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards get DC support, nouveau got a bump in displayport support with common code extraction from i915. Outside of drm this contains a couple of patches for hexint moduleparams which you've acked, and a virtio common code tree that you should also get via it's regular path.

struct s5k5baf_fw ends with this: struct { u16 id; u16 offset; } seq[0]; u16 data[]; }; which is rather confusing and can cause gcc warnings: s5k5baf.c: In function 's5k5baf_load_setfile.isra': s5k5baf.c:390:13: warning: array subscript 65535 is outside the bounds of an interior zero-length array 'struct <anonymous>[0]' [-Wzero-length-bounds] 390 | if (f->seq[i].offset + d <= end) | ~~~~~~^~~ It turns out that 'data[]' is used in only one place and it can easily be replaced by &fw->seq[0].id and 'seq[0]' can be replaced by 'seq[]'. This is both more readable and solved that warnings.
