Old versions of the svga device used to export virtual vram, handling of which was optimized on top of transparent hugepages support. Only very old devices (OpenGL 2.1 support and earlier) used this code and at this point performance differences are negligible. Because the code requires very old hardware versions to run it has been largely untested and unused for a long time. Furthermore removal of the ttm hugepages support in: commit 0d979509 ("drm/ttm: remove ttm_bo_vm_insert_huge()") broke the coherency mode in vmwgfx when running with hugepages. Fixes: 0d979509 ("drm/ttm: remove ttm_bo_vm_insert_huge()") Signed-off-by:

On i386 size_t is of course 32bits and using long int throws warnings, trivially fix it by using the dedicated size_t format.

This changes the way the regmap is allocated to prepare for the later addition of the JZ4780 which has more registers and bits than the others. Therefore we make the regmap as big as the reg property in the device tree tells. Suggested-by:

Maxime Ripard authored
Several DRM/KMS atomic commits can run in parallel if they affect different CRTC. These commits share the global HVS state, so we have some code to make sure we run commits in sequence. This synchronization code is one of the first thing that runs in vc4_atomic_commit_tail(). Another constraints we have is that we need to make sure the HVS clock gets a boost during the commit. That code relies on clk_set_min_rate and will remove the old minimum and set a new one. We also need another, temporary, minimum for the duration of the commit. The algorithm is thus to set a temporary minimum, drop the previous one, do the commit, and finally set the minimum for the current mode. However, the part that sets the temporary minimum and drops the older one runs before the commit synchronization code. Thus, under the proper conditions, we can end up mixing up the minimums and ending up with the wrong one for our current step. To avoid it, let's move the clock setup in the protected section.

There are a few details specific to the GETFB2 IOCTL. It's not immediately clear how user-space should check for the number of planes. Suggest using the handles field or the pitches field. The modifier array is filled with zeroes, ie. DRM_FORMAT_MOD_LINEAR. So explicitly tell user-space to not look at it unless the flag is set. Changes in v2 (Daniel): - Mention that handles should be used to compute the number of planes, and only refer to pitches as a fallback. - Reword bit about undefined modifier. Signed-off-by:

The checks performed by commit aed9d65a ("USB: validate wMaxPacketValue entries in endpoint descriptors") require that initial value of the maxp variable contains both maximum packet size bits (10..0) and multiple-transactions bits (12..11).
