Irui Wang [Wed, 20 Jul 2022 08:57:26 +0000 (10:57 +0200)]
media: mediatek: vcodec: Add encoder driver support for 34-bit iova

Encoder driver got iova from IOMMU is 34-bit, for example:

Here is the sample code:
encoder input frame buffer dma address is:
frm_buf =
    vb2_dma_contig_plane_dma_addr(&vb2_v4l2_buffer->vb2_buf, 0);
the value of frm_buf is 0x1_ff30_0000.

encoder driver got the frm_buf and send the iova to SCP firmware
through SCP IPI message, then write to encoder hardware in SCP.
The iova is stored in IPI message as uint32_t data type, so the
value will be truncated from *0x1_ff30_0000* to *0xff30_0000*,
and then *0xff30_0000* will be written to encoder hardware, but
IOMMU will help to add the high *0x1_* bit back, so IOMMU can
translate the iova to PA correctly, encoder hardware can access
the correct memory for encoding.
Another reason to do this is the encoder hardware can't access
the 34-bit iova, IOMMU will help to add the remaining high bits
of iova. But for mt8188, encoder hardware can access 34-bit iova
directly, and encoder driver need write all 34 bits because
IOMMU can't help driver do this if the hardware support access
34-bit iova.
For the reasons above, this patch is added to support transfer
34-bit iova between kernel and SCP encoder driver. Use uint64_t
data type to store the iova, for compatibility with old chipsets,
add some new struct definitions for 34-bit.

media: ti: cal: fix wdma irq for metadata

CAL HW interrupts are inherently racy. If we get both start and end
interrupts, we don't know what has happened: did the DMA for a single
frame start and end, or did one frame end and a new frame start?

Usually for normal pixel frames we get the interrupts separately. If
we do get both, we have to guess. The assumption in the code is that the
active vertical area is larger than the blanking vertical area, and thus
it is more likely that we get the end of the old frame and the start of
a new frame.

However, for embedded data, which is only a few lines high, we always
get both interrupts. Here the assumption is that we get both for the
same frame.

media: ti: cal: use CSI-2 frame number for seq number

The userspace needs a way to match received metadata buffers to pixel
data buffers. The obvious way to do this is to use the CSI-2 frame
number, as both the metadata and the pixel data have the same frame
number as they come from the same frame.

However, we don't have means to convey the frame number to userspace. We
do have the 'sequence' field, which with a few tricks can be used for
this purpose.

To achieve this, track the frame number for each virtual channel and
increase the sequence for each virtual channel by frame-number -
previous-frame-number, also taking into account the eventual wrap of the
CSI-2 frame number. If the CSI-2 peripheral does not support frame
numbers, CAL increases the frame number register by one each frame.

This way we get a monotonically increasing sequence number which is
common to all streams using the same virtual channel.

Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP
core found on i.MX8MP SoC.

The processor core applies a programmable geometrical transformation on
input images to correct distorsion introduced by lenses.
The transformation function is exposed as a grid map with 16x16 pixel
macroblocks indexed using X, Y vertex coordinates.

The dewarping map can be set from application through a dedicated v4l2
control. If not set or invalid, the driver computes an identity map
prior to starting the processing engine.

The driver supports scaling, cropping and pixel format conversion.

2 years agoperf test: Refactor shell tests allowing subdirs
Carsten Haitzler [Fri, 12 Aug 2022 12:16:28 +0000 (13:16 +0100)]
perf test: Refactor shell tests allowing subdirs

This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.
