2022-03-18media: platform: place stm32/ and sti/ under st/ dirMauro Carvalho Chehab1-409/+0
As the end goal is to have platform drivers split by vendor, move both stm32/ and sti/ for them to be inside st/ directory. Acked-by: Hugues Fruchet <hugues.fruchet@st.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

2018-01-04media: fix usage of whitespaces and on indentationMauro Carvalho Chehab1-1/+1
On several places, whitespaces are being used for indentation, or even at the end of the line. Fix them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2017-01-31[media] st-hva: add debug file systemJean-Christophe Trotin1-1/+87
This patch creates 4 static debugfs entries to dump: - the device-related information ("st-hva/device") - the list of registered encoders ("st-hva/encoders") - the current values of the hva registers ("st-hva/regs") - the information about the last closed instance ("st-hva/last") It also creates dynamically a debugfs entry for each opened instance, ("st-hva/<instance identifier>") to dump: - the information about the frame (format, resolution) - the information about the stream (format, profile, level, resolution) - the control parameters (bitrate mode, framerate, GOP size...) - the potential (system, encoding...) errors - the performance information about the encoding (HW processing duration, average bitrate, average framerate...) Each time a running instance is closed, its context (including the debug information) is saved to feed, on demand, the last closed instance debugfs entry.

2017-01-31[media] st-hva: encoding summary at instance releaseJean-Christophe Trotin1-0/+8
This patch adds a short summary about the encoding operation at each instance closing, for debug purpose (through dev_dbg()): - information about the frame (format, resolution) - information about the stream (format, profile, level, resolution) - number of encoded frames - potential (system, encoding...) errors Signed-off-by: Yannick Fertre <yannick.fertre@st.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Jean-Christophe Trotin <jean-christophe.trotin@st.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] st-hva: add H.264 video encoding supportJean-Christophe Trotin1-5/+30
This patch adds the H.264 video encoding capability in the V4L2 HVA video encoder driver for STMicroelectronics SoC (hva-h264.c). The main supported features are: - profile: baseline, main, high, stereo high - level: up to 4.2 - bitrate mode: CBR, VBR - entropy mode: CABAC, CAVLC - video aspect: 1x1 only Signed-off-by: Yannick Fertre <yannick.fertre@st.com> Signed-off-by: Jean-Christophe Trotin <jean-christophe.trotin@st.com> Acked-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09[media] st-hva: multi-format video encoder V4L2 driverJean-Christophe Trotin1-0/+290
This patch adds V4L2 HVA (Hardware Video Accelerator) video encoder driver for STMicroelectronics SoC. It uses the V4L2 mem2mem framework. This patch only contains the core parts of the driver: - the V4L2 interface with the userland (hva-v4l2.c) - the hardware services (hva-hw.c) - the memory management utilities (hva-mem.c) This patch doesn't include the support of specific codec (e.g. H.264) video encoding: this support is part of subsequent patches.
