* drm/rockchip: fix wrong pitch/size using on gemMark Yao2016-01-211-7/+2
| | | | | | | | | | | | | | | | args->pitch and args->size may not be set by userspace, sometimes userspace only malloc args and not memset args to zero, then args->pitch and args->size is random, it is very danger to use pitch/size on gem. pitch's type is u32, and min_pitch's type is int, example, pitch is 0xffffffff, then pitch < min_pitch return true, then gem will alloc very very big bufffer, it would eat all the memory and cause kernel crash. Stop using pitch/size from args, calc them from other args. Signed-off-by: Mark Yao <mark.yao@rock-chips.com>

* drm/rockchip: don't wait for vblank if fb hasn't changedJohn Keeping2016-01-201-2/+6
| | | | | | | | | | | | | | | | | | | | As commented in drm_atomic_helper_wait_for_vblanks(), userspace relies on cursor ioctls being unsynced. Converting the rockchip driver to atomic has significantly impacted cursor performance by making every cursor update wait for vblank. By skipping the vblank sync when the framebuffer has not changed (as is done in drm_atomic_helper_wait_for_vblanks()) we can avoid this for the common case of moving the cursor and only need to delay the cursor ioctl when the cursor icon changes. We cannot add the check on legacy_cursor_update since that results in the cursor bo being unreferenced while the hardware may still be reading it. Fully supporting unsynced cursor updates is left for the future when the atomic helper framework supports async updates.

| | | | | | | | | | | | Commit dbb3d94 (drm/rockchip: vop: move interrupt registers into vop_data) introduced new macros for updating the interrupt control registers but these always use the mask from the register definition without refining it for the particular bits that are being changed. This means that whenever we enable/disable a particular interrupt we end up disabling all of the others as a side effect. Signed-off-by: John Keeping <john@metanate.com>

| | | | | | | | | | | | | | | | | | The following code pattern exists in some DRM drivers: ddev = drm_dev_alloc(&driver, parent_dev); drm_dev_set_unique(ddev, dev_name(parent_dev)); (Sometimes dev_name(ddev->dev) is used, which is the same.) As suggested in http://lists.freedesktop.org/archives/dri-devel/2015-December/096441.html, the unique name of a new DRM device can be set as dev_name(parent_dev) when parent_dev is not NULL (vgem is a special case).

* drm: make drm_dev_set_unique() not use a format stringNicolas Iooss2015-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | drm_dev_set_unique() uses a format string to define the unique name of a device. This feature is not used as currently all the calls to this function either use "%s" as a format string or directly use dev_name(). Even though this second kind of call does not introduce security problems, because there cannot be "%" characters in dev_name() results, gcc issues a warning when building with -Wformat-security flag ("warning: format string is not a string literal (potentially insecure)"). This warning is useful to find real bugs like the one fixed by commit 3958b79266b1 ("configfs: fix kernel infoleak through user-controlled format string"). False positives which do not bring an extra value make the work of finding real bugs harder. Therefore remove the format-string feature from drm_dev_set_unique().

| | | | | | | | | | | | | | | | | | | | | | | | Commit 371f0f085f629 ("ARM: 8426/1: dma-mapping: add missing range check in dma_mmap()") introduced offset-checking for mappings, which collides with the fake-offset the drm sets for gems. Other drm-drivers set this offset to 0 before doing the mapping, so this looks like the correct way to go for rockchip as well.

| * drm/rockchip: vop: Correct enabled clocks during setupSjoerd Simons2015-12-011-22/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When doing the initial setup both the hclk and the aclk need to be enabled otherwise the board will simply hang. This only occurs when building the vop driver as a module, when its built-in the initial setup happens to run before the clock framework shuts of unused clocks (including the aclk). While there also switch to doing prepare and enable in one step rather then separate steps to reduce the amount of code required.

* drm: Stop using drm_vblank_count() as the hw frame counterVille Syrjälä2015-10-071-1/+1
| | | | | | | | | | | | | | | | | drm_vblank_count() returns the software counter. We should not pretend it's the hw counter since we use the hw counter to figuere out what the software counter value should be. So instead provide a new function drm_vblank_no_hw_counter() for drivers that don't have a real hw counter. The new function simply returns 0, which is about the only thing it can do.
