* [PATCH 0/3] 32-bit Meson: add the canvas module @ 2019-04-13 17:15 Martin Blumenstingl 2019-04-13 17:15 ` [PATCH 1/3] ARM: dts: meson8: " Martin Blumenstingl ` (3 more replies) 0 siblings, 4 replies; 8+ messages in thread From: Martin Blumenstingl @ 2019-04-13 17:15 UTC (permalink / raw) To: linux-amlogic, khilman Cc: mjourdan, Martin Blumenstingl, linux-kernel, linux-arm-kernel This adds the canvas module on Meson8, Meson8b and Meson8m2. The canvas IP is used by the video decoder hardware as well as the VPU (video output) hardware. Neither the VPU nor the video decoder driver support the 32-bit SoCs yet. However, we can still add the canvas module to have it available once these drivers gain support for the older SoCs. I have tested this on my Meson8m2 board by hacking the VPU driver to not re-initialize the VPU (and to use the configuration set by u-boot). With that hack I could get some image out of the CVBS connector. No changes to the canvas driver were required. Due to lack of hardware I could not test Meson8, but I'm following (as always) what the Amlogic 3.10 vendor kernel uses. Meson8b is also not tested because u-boot of my EC-100 doesn't have video output enabled (so I couldn't use the same hack I used on my Meson8m2 board).

The canvas module is located inside thie "DMC bus" (where also some of the memory controller registers are located). The "DMC bus" itself is part of the so-called "MMC bus". Amlogic's vendor kernel has an explicit #define for the "DMC" register range on Meson8m2 while there's no such #define for Meson8. However, the canvas and memory controller registers on Meson8 are all expressed as "0x6000 + actual offset", while Meson8m2 uses "DMC + actual offset". Thus it's safe to assume that the DMC bus exists on both SoCs even though the registers inside are slightly different.

The canvas IP before the GX* generation does not handle what Amlogic calls "endianness", the field that allows doing some byte-switching to get proper NV12/NV21. So the following defines are unusable: #define MESON_CANVAS_ENDIAN_SWAP16 0x1 #define MESON_CANVAS_ENDIAN_SWAP32 0x3 #define MESON_CANVAS_ENDIAN_SWAP64 0x7 #define MESON_CANVAS_ENDIAN_SWAP128 0xf It wouldn't change much functionally, but we could have e.g a warning if a m8 canvas user tries to set endianness even though it does nothing.

Amlogic uses different defines for Meson8 and Meson8m2 in their vendor kernel and they keep Meson8b different. I will add three new compatibles, one for each SoC (Meson8, Meson8b, Meson8m2) just to be on the safe side if we discover differences in the canvas IP on these SoCs. what do you think? > It wouldn't change much functionally, but we could have e.g a warning > if a m8 canvas user tries to set endianness even though it does > nothing. this is a good idea, that will make it easier to spot why something doesn't work. we can also return -EINVAL, like you already do for the case where the canvas ID is already used.
