Platform devices might operate on firmware framebuffers, such as VESA or EFI. Before a native driver for the graphics hardware can take over the device, it has to remove any platform driver that operates on the firmware framebuffer. Aperture helpers provide the infrastructure for native drivers to remove the generic ones. For now, this only concerns generic fbdev drivers. Code for removing these is provided by drm_fb_helper_remove_conflicting_framebuffers() et al. Simply wrap these functions for now. At a later point, code can be added for generic DRM drivers to acquire firmware framebuffers. v2: * fix docs for drm_aperture_remove_framebuffers() Signed-off-by:

Since we're about to move drm_dp_helper.c over to drm_dbg_*(), we'll want to make sure that we can also add ratelimited versions of these macros in order to retain some of the previous debugging output behavior we had. However, as I was preparing to do this I noticed that the current rate limited macros we have are kind of bogus. It looks like when I wrote these, I didn't notice that we'd always be calling __ratelimit() even if the debugging message we'd be printing would normally be filtered out due to the relevant DRM debugging category being disabled. So, let's fix this by making sure to check drm_debug_enabled() in our ratelimited macros before calling __ratelimit(), and start using drm_dev_printk() in order to print debugging messages since that will save us from doing a redundant drm_debug_enabled() check. And while we're at it, let's move the code for this into another macro that we can reuse for defining new ratelimited DRM debug macros more easily. v2: * Make sure to use tabs where possible in __DRM_DEFINE_DBG_RATELIMITED() Signed-off-by:

As pointed out by the documentation for drm_dp_aux_register(), drm_dp_aux_init() should be used in situations where the AUX channel for a display driver can potentially be registered before it's respective DRM driver. This is the case with Tegra, since the DP aux channel exists as a platform device instead of being a grandchild of the DRM device. Since we're about to add a backpointer to a DP AUX channel's respective DRM device, let's fix this so that we don't potentially allow userspace to use the AUX channel before we've associated it with it's DRM connector.

drm_vblank_restore() exists because certain power saving states can clobber the hardware frame counter. The way it does this is by guesstimating how many frames were missed purely based on the difference between the last stored timestamp vs. a newly sampled timestamp. If we should call this function before a full frame has elapsed since we sampled the last timestamp we would end up with a possibly slightly different timestamp value for the same frame. Currently we will happily overwrite the already stored timestamp for the frame with the new value. This could cause userspace to observe two different timestamps for the same frame (and the timestamp could even go backwards depending on how much error we introduce when correcting the timestamp based on the scanout position). To avoid that let's not update the stored timestamp at all, and instead we just fix up the last recorded hw vblank counter value such that the already stored timestamp/seq number will match. Thus the next time a vblank irq happens it will calculate the correct diff between the current and stored hw vblank counter values. Sidenote: Another possible idea that came to mind would be to do this correction only if the power really was removed since the last time we sampled the hw frame counter. But to do that we would need a robust way to detect when it has occurred. Some possibilities could involve some kind of hardare power well transition counter, or potentially we could store a magic value in a scratch register that lives in the same power well. But I'm not sure either of those exist, so would need an actual investigation to find out. All of that is very hardware specific of course, so would have to be done in the driver code.

If the user specifies zero width/height cmdline mode i915 will blow up as the fbdev path will bypass the regular fb sanity check that would otherwise have refused to create a framebuffer with zero width/height. The reason I thought to try this is so that I can force a specific depth for fbdev without actually having to hardcode the mode on the kernel cmdline. Eg. if I pass video=0x0-8 I will get an 8bpp framebuffer at my monitor's native resolution. Signed-off-by:
