Exynos DRM drivers should work with and without IOMMU. Providing common API generic to both scenarios should make code cleaner and allow further code improvements. The patch removes including of exynos_drm_iommu.h as the file contains mostly IOMMU specific stuff, instead it exposes exynos_drm_*_dma functions and puts them into exynos_drm_dma.c. Signed-off-by:

This is the same as the default drm_gem_dumb_map_offset() implementation, except that this one missed the ban on userspace mapping an imported dmabuf (which seems like intended common behavior for drivers). Signed-off-by:

This change is an attempt to handle the alternate clock for the CEA mode. 60Hz vs. 59.94Hz, 30Hz vs 29.97Hz or 24Hz vs 23.97Hz on the Amlogic Meson SoC DRM Driver pixel clock generation. The actual clock generation will be moved to the Common Clock framework once all the video clock are handled by the Amlogic Meson SoC clock driver, then these alternate timings will be handled in the same time in a cleaner fashion.

Our hardware requires the pitch to be an even number when using YUV formats with the frontend. Implement a driver-specific callback for GEM dumb allocation that sets the pitch accordingly. Since only the bpp is passed (and not the format), we cannot really distinguish if this alignment is really required. Since it doesn't hurt to align the pitch anyway, always do it. Signed-off-by:

The frontend comes with two "channels", that can be configured independently. When used in YUV mode, the first channel (CH0) represents the luminance component while the second channel (CH1) represents the chrominance. In RGB mode, both have to be configured the same way. Use variables (with the YUV terminology) for each channel's dimensions, calculating the chroma dimensions from the luma dimensions and the sub-sampling factors from the format description. Since the configured size only has pixel precision, the fractional fixed-point part of the source size is dropped for both components to ensure that the scaling factors are accurate. Signed-off-by:

This introduces new helpers for retrieving the input data mode and pixel sequence register field values based on the DRM format instead of hardcoding these. This makes it easier to add support for more formats. Signed-off-by:

In order to support YUV to RGB conversion with the frontend (which is generally used for connecting with the backend), the CSC block must not be bypassed. As a result, the bit to enable CSC bypass is moved from the runtime resume routine to the format update routine, so that it can disabled when introducing support for YUV formats later. Signed-off-by:

Since more formats can be supported by the frontend, rename the variable listing the layer formats to avoid suggesting that the backend itself supports all the listed formats. Signed-off-by:

Our hardware has a limited number of YUV planes (usually 1) that can be supported using the backend only. However, YUV planes can also be supported by the frontend and must then not be counted when checking for that limitation. Only count the YUV plane when the frontend is not used. Signed-off-by:
-
Paul Kocialkowski authored
Before this patch, it is assumed that a plane is supported either through the frontend or through the backend alone. However, the DRM interface does not allow finely reporting our hardware capabilities and there are cases where neither are support. In particular, some plane formats are supported by the backend and not the frontend, so they can only be supported without scaling. Signed-off-by:
-
Paul Kocialkowski authored
Checking that scaling is in use is not sufficient as a condition to decide to use the frontend. Since not all layer formats are supported by the frontend, we need to check for that support first. Then, the frontend must only be enabled if the backend doesn't support the format or that scaling is required. Signed-off-by:

In order to check whether the frontend supports a specific format, an explicit list and a related helper are introduced. Just like in the backend, the prototype of the helper is added to the frontend header so that it can be used later on. The helper is also exported because it will be used outside of the frontend module. Signed-off-by:

The backend allows integer-only scaling but can handle alpha components, unlike the frontend. It could be useful to add support for this eventually, so add a short TODO comment describing the situation. Signed-off-by:
-
Paul Kocialkowski authored
The frontend documentation (for the A33) mentions that ARGB is supported as output, but with the alpha component always set to 0xff. In practice, this means that the alpha component cannot be preserved when going through the frontend. Since the information is lost, ARGB is not properly supported. As a result, expose the matching format supported by the frontend (both for input and output) as XRGB instead of ARGB. Since ARGB was the selected format for connecting the frontend to the backend, change it to XRGB to reflect this as well. The A31 and A80 SoCs apparently have a bit to enable proper alpha, but this is not supported at this point (see the comment already in the code). Signed-off-by:

This adds a dedicated function for cleaning the video and YUV source channel layer enable bits. This function is called first on layer atomic update to make sure that there are no leftover bits from previous plane configuration that were not cleaned until now. It fixes issues when alternating between video and YUV planes, where both bits would be set eventually, leading to broken plane display. Signed-off-by:

Pull XArray updates from Matthew Wilcox: "We found some bugs in the DAX conversion to XArray (and one bug which predated the XArray conversion). There were a couple of bugs in some of the higher-level functions, which aren't actually being called in today's kernel, but surfaced as a result of converting existing radix tree & IDR users over to the XArray. Some of the other changes to how the higher-level APIs work were also motivated by converting various users; again, they're not in use in today's kernel, so changing them has a low probability of introducing a bug.
