* [PATCH 3/4] drm/meson: overlay: setup overlay for Amlogic FBC
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
In-Reply-To: <20200220162758.13524-1-narmstrong@baylibre.com>
Setup the Amlogic FBC decoder for the VD1 video overlay plane.
The VD1 Amlogic FBC decoder is integrated in the pipeline like the
YUV pixel reading/formatter but used a direct memory address instead.
The default mode needs to calculate the content body size since the header
is allocated after.
The scatter mode needs a simplier management since only the header is needed,
since it contains an IOMMU scatter table to locate the superblocks in memory.

* [PATCH 0/4] drm/meson: add support for Amlogic Video FBC
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
Amlogic uses a proprietary lossless image compression protocol and format
for their hardware video codec accelerators, either video decoders or
video input encoders.
It considerably reduces memory bandwidth while writing and reading
frames in memory.
The underlying storage is considered to be 3 components, 8bit or 10-bit
per component, YCbCr 420, single plane :
- DRM_FORMAT_YUV420_8BIT
- DRM_FORMAT_YUV420_10BIT
This modifier will be notably added to DMA-BUF frames imported from the V4L2
Amlogic VDEC decoder.
At least two options are supported :
- Scatter mode: the buffer is filled with a IOMMU scatter table referring
to the encoder current memory layout. This mode if more efficient in terms
of memory allocation but frames are not dumpable and only valid during until
the buffer is freed and back in control of the encoder
- Memory saving: when the pixel bpp is 8b, the size of the superblock can
be reduced, thus saving memory.
This serie adds the missing register, updated the FBC decoder registers
content to be committed by the crtc code.
The Amlogic FBC has been tested with compressed content from the Amlogic
HW VP9 decoder on S905X (GXL), S905D2 (G12A) and S905X3 (SM1) in 8bit
(Scatter+Mem Saving on G12A/SM1, Mem Saving on GXL) and 10bit
(Scatter on G12A/SM1, default on GXL).
It's expected to work as-is on GXM and G12B SoCs.

Yes, this a mistake. The error should be properly propagated to the callers
(that is hd3ss3220_probe)
Also in the mainline. I will fix it in v2 and in mainline.
Thank you for the good catch,

* [PATCH 3/4] drm/meson: overlay: setup overlay for Amlogic FBC
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: Neil Armstrong, linux-amlogic, linux-arm-kernel, linux-kernel
In-Reply-To: <20200220162758.13524-1-narmstrong@baylibre.com>
Setup the Amlogic FBC decoder for the VD1 video overlay plane.
The VD1 Amlogic FBC decoder is integrated in the pipeline like the
YUV pixel reading/formatter but used a direct memory address instead.
The default mode needs to calculate the content body size since the header
is allocated after.
The scatter mode needs a simplier management since only the header is needed,
since it contains an IOMMU scatter table to locate the superblocks in memory.

* [PATCH 0/4] drm/meson: add support for Amlogic Video FBC
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
Amlogic uses a proprietary lossless image compression protocol and format
for their hardware video codec accelerators, either video decoders or
video input encoders.
It considerably reduces memory bandwidth while writing and reading
frames in memory.
The underlying storage is considered to be 3 components, 8bit or 10-bit
per component, YCbCr 420, single plane :
- DRM_FORMAT_YUV420_8BIT
- DRM_FORMAT_YUV420_10BIT
This modifier will be notably added to DMA-BUF frames imported from the V4L2
Amlogic VDEC decoder.
At least two options are supported :
- Scatter mode: the buffer is filled with a IOMMU scatter table referring
to the encoder current memory layout. This mode if more efficient in terms
of memory allocation but frames are not dumpable and only valid during until
the buffer is freed and back in control of the encoder
- Memory saving: when the pixel bpp is 8b, the size of the superblock can
be reduced, thus saving memory.
This serie adds the missing register, updated the FBC decoder registers
content to be committed by the crtc code.
The Amlogic FBC has been tested with compressed content from the Amlogic
HW VP9 decoder on S905X (GXL), S905D2 (G12A) and S905X3 (SM1) in 8bit
(Scatter+Mem Saving on G12A/SM1, Mem Saving on GXL) and 10bit
(Scatter on G12A/SM1, default on GXL).
It's expected to work as-is on GXM and G12B SoCs.

Hi Daniel,
As one can see in __qla2x00_marker() a value is assigned to
mrk24->handle() by __qla2x00_alloc_iocbs(). That function calls
qla2xxx_get_next_handle() to determine the 'handle' value. The
implementation of that last function is as follows:
uint32_t qla2xxx_get_next_handle(struct req_que *req)
{
uint32_t index, handle = req->current_outstanding_cmd;
for (index = 1; index < req->num_outstanding_cmds; index++) {
handle++;
if (handle == req->num_outstanding_cmds)
handle = 1;
if (!req->outstanding_cmds[handle])
return handle;
}
return 0;
}
Since 'num_outstanding_cmds' is a 16-bit variable I think that
guarantees that the code quoted in your e-mail passes a 16-bit value as
the second argument to make_handle().
Additionally, if the second argument to make_handle() would be larger
than 0x10000, the following code from qla2x00_status_entry() would map
sts->handle to another queue and another command than those through wich
the command was submitted to the firmware:
handle = (uint32_t) LSW(sts->handle);
que = MSW(sts->handle);
req = ha->req_q_map[que];
Bart.

I went deeper in the volume_key code and found that gnupg2 is needed at
runtime to create packet with passphrase, so even if build doesn't fail
gnupg2 is needed at runtime. In gcr packet is the same.
But then, it turns out that gnupg2's binary name is gpg and not gpg2,
but usually gpg2 name is used(i.e. on Ubuntu 19.10). Also in gcr package
they assume its name is gpg2 but if you try to build you find gpg.
Gnupg2 failure is difficult to find since it's at runtime(i.e. gpgme
calls /usr/bin/gpg2 to encrypt/decrypt something).
So what do you suggest? Better change gpg binary file name to gpg2 or
better fix gcr package to use /usr/bin/gpg instead of /usr/bin/gpg2 And
do the same here with volume-key?
Gcr package is wrong in any case at the moment, so it must be fixed, and
find someone who's able to test it.
Best regards

* [PATCH 1/4] drm/fourcc: Add modifier definitions for describing Amlogic Video Framebuffer Compression
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
In-Reply-To: <20200220162758.13524-1-narmstrong@baylibre.com>
Amlogic uses a proprietary lossless image compression protocol and format
for their hardware video codec accelerators, either video decoders or
video input encoders.
It considerably reduces memory bandwidth while writing and reading
frames in memory.
The underlying storage is considered to be 3 components, 8bit or 10-bit
per component, YCbCr 420, single plane :
- DRM_FORMAT_YUV420_8BIT
- DRM_FORMAT_YUV420_10BIT
This modifier will be notably added to DMA-BUF frames imported from the V4L2
Amlogic VDEC decoder.
At least two options are supported :
- Scatter mode: the buffer is filled with a IOMMU scatter table referring
to the encoder current memory layout. This mode if more efficient in terms
of memory allocation but frames are not dumpable and only valid during until
the buffer is freed and back in control of the encoder
- Memory saving: when the pixel bpp is 8b, the size of the superblock can
be reduced, thus saving memory.

Haven't managed to crash it yet, but every run complains:
got to shutdown of 10 with refcnt: 2
Refs being all dropped, calling forget for 10
terminate called after throwing an instance of 'fmt::v6::format_error'
what(): argument index out of range
unknown location(0): fatal error: in "unixdomain_server": signal: SIGABRT (application abort requested)
Not sure if that's causing it not to fail here.

* [PATCH 3/4] drm/meson: overlay: setup overlay for Amlogic FBC
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
In-Reply-To: <20200220162758.13524-1-narmstrong@baylibre.com>
Setup the Amlogic FBC decoder for the VD1 video overlay plane.
The VD1 Amlogic FBC decoder is integrated in the pipeline like the
YUV pixel reading/formatter but used a direct memory address instead.
The default mode needs to calculate the content body size since the header
is allocated after.
The scatter mode needs a simplier management since only the header is needed,
since it contains an IOMMU scatter table to locate the superblocks in memory.

* [PATCH 3/4] drm/meson: overlay: setup overlay for Amlogic FBC
From: Neil Armstrong @ 2020-02-20 16:27 UTC (permalink / raw)
To: daniel, dri-devel
Cc: linux-amlogic, linux-kernel, linux-arm-kernel, Neil Armstrong
In-Reply-To: <20200220162758.13524-1-narmstrong@baylibre.com>
Setup the Amlogic FBC decoder for the VD1 video overlay plane.
The VD1 Amlogic FBC decoder is integrated in the pipeline like the
YUV pixel reading/formatter but used a direct memory address instead.
The default mode needs to calculate the content body size since the header
is allocated after.
The scatter mode needs a simplier management since only the header is needed,
since it contains an IOMMU scatter table to locate the superblocks in memory.
Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

Is there a reason you decided not to return the first subcluster as
allocated? (As you had proposed in v2)

* [PATCH v2 0/8] firmware: imx: Align imx SC msg structs to 4
From: Leonard Crestez @ 2020-02-20 16:29 UTC (permalink / raw)
To: Shawn Guo, Dong Aisheng
Cc: Fabio Estevam, Michael Turquette, Stephen Boyd, Stefan Agner,
Linus Walleij, Alessandro Zummo, Alexandre Belloni, Anson Huang,
Abel Vesa, Franck LENORMAND, kernel, linux-imx, linux-arm-kernel,
linux-clk, linux-gpio, linux-rtc
The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have sizeof "6" and "7".
This produces many oopses with CONFIG_KASAN=y:
BUG: KASAN: stack-out-of-bounds in imx_mu_send_data+0x108/0x1f0
It shouldn't cause an issues in normal use because these structs are
always allocated on the stack but tools like KASAN are very useful on
stable kernels.
Chnages since v1:
* Split into many patches with individual fixes: tags
