So after a lot of digging around in git histories it looks like this has only ever be used by dri1 render clients. Hence we can fully disable the entire thing for modesetting drivers and so greatly reduce the attack surface for potential exploits (or at least tools like trinity ...). Also add the drm_legacy prefix for functions which are called from common code. To further reduce the impact on common code also extract all the ctx release handling into a function (instead of only releasing individual handles) and make ctxbitmap_cleanup return void - it can never fail.

Now only legacy ums drivers have the DRIVER_HAVE_DMA driver feature flag set, so strictly speaking the modesetting check is redundant. But adding it has the upside that it makes it very clear that the dma support is legacy stuff. Reviewed-by:

And hide the checks a bit better. This was already disallowed for modesetting drivers, so no functinal change here. Reviewed-by:

Only the radeon/r128/ati ums drivers use this. Furthermore the cleanup was already only done for UMS drivers. Also a quick check of the ATI ddx git history shows that only the UMS code ever used this facility. So we can safely disallow these pair of ioctls for modesetting drivers. Reviewed-by:

I've decided that some clear markers for what's legacy dri1/non-gem code is useful. I've opted to use the drm_legacy prefix and then hide all the checks in that function for better readability in the common code. Reviewed-by:

Totally unused, so just rip it out. Anyway, we want drivers to be fully backwards compatible, allowing them to change behaviour is just a recipe for them to break badly. Reviewed-by:

When switching between various drivers for this device, it's possible that some critical registers are left containing values which affect the device operation. One such case encountered is the VIP output mux register. This defaults to 0x24 on powerup, but other drivers may set this to 0x12. This results in incorrect colours. Fix this by ensuring that the register is always set to the power on default setting. Signed-off-by:

Split the output routing specification between SoC-internal data, specified in the rcar_du_device_info structure, and board data, passed through platform data. The DU has 5 possible outputs (DPAD0/1, LVDS0/1, TCON). SoC-internal output routing data specify which output are valid, which CRTCs can be connected to the valid outputs, and the type of in-SoC encoder for the output. Platform data then specifies external encoders and the output they are connected to. Signed-off-by: -

The R8A7779 DU is split in per-CRTC resources (scan-out engine, blending unit, timings generator, ...) and device-global resources (start/stop control, planes, ...) shared between the two CRTCs. The R8A7790 introduced a third CRTC with its own set of global resources This would be modeled as two separate DU device instances if it wasn't for a handful or resources that are shared between the three CRTCs (mostly related to input and output routing). For this reason the R8A7790 DU must be modeled as a single device with three CRTCs, two sets of "semi-global" resources, and a few device-global resources. Introduce a new rcar_du_group driver-specific object, without any real counterpart in the DU documentation, that models those semi-global resources. Signed-off-by: -
