The GEM CMA helpers uses a custom mmap implementation based on remap_pfn_range(). While this works when the buffer DMA and physical addresses are identical, it fails to take IOMMU into account and tries to mmap the buffer to userspace using the DMA virtual address instead of the physical address. This results in mapping random physical pages when the device is behind an IOMMU. Use the DMA mapping dma_mmap_writecombine() function instead. Signed-off-by:

entry->size is the size of the node, not the size of the hole after it. So the code would actually find the hole which can satisfy the constraints and which is preceded by the smallest node, not the smallest hole satisfying the constraints. Reported-by:

Currently drm_pick_cmdline_mode() doesn't care about the interlace when the given mode line has no "i" suffix. That is, when there are multiple entries for the same resolution, an interlace mode might be picked up just depending on the assigned order, and there is no way to exclude it. This patch changes the logic for the mode selection, to prefer the noninterlace mode unless the interlace mode is explicitly given. When no matching mode is found, it still tries the interlace mode as fallback. Signed-off-by:

This decreases eviction by up to 20%, by improving the fragmentation quality. No harm in normal cases that fit VRAM fully (PTS gaming suite). In some cases, even the VRAM-fitting cases improved slightly (openarena, urban terror). 512kb was measured as the most optimal threshold for 3d workloads common to radeon. Other drivers may need different thresholds according to their workloads. v2: Nicer formatting Signed-off-by:

Clients like i915 need to segregate cache domains within the GTT which can lead to small amounts of fragmentation. By allocating the uncached buffers from the bottom and the cacheable buffers from the top, we can reduce the amount of wasted space and also optimize allocation of the mappable portion of the GTT to only those buffers that require CPU access through the GTT. For other drivers, allocating small bos from one end and large ones from the other helps improve the quality of fragmentation.

Here's the latest iteration of the universal planes work, which I believe is finally ready for merging. Aside from the minor driver patches to use the new drm_for_each_legacy_plane() macro for plane loops, these should all have an r-b from Rob Clark now.

This is the equivalent change in the crtc helpers as done to the i915 modeset infrastructure in commit b0a2658a Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Dec 18 09:37:54 2012 +0100 drm/i915: don't disable disconnected outputs This was originally introduced to make encoder sharing on radone easier for userspace, but: - It is policy and as such belongs into userspace. E.g. personally I'm fairly annoyed that a flaky cable results in permanent changes of the desktop layout, so I'll kick out DEs which do this. Worse if the kernel also tries to be clever. - It's inconsistent: We only kill disconnected outputs on setCrtc (which userspace might also call when just changing the framebuffer), but not when e.g. we receive a hpd event or in the output poll worker. - It's unexpected behaviour for the userspace driver, at least in the intel ddx we've had tons of bugs where the driver fell over and killed the X session becuase pageflips/vblanks suddenly stopped working. We've had to fix this by wrapping every single setCrtc int a big "recover kms state from the kernel again" operation. - It's suprising for the kernel, too: It took a few mails between Rob, Matt and me for them to notice that little dragon wreaking havoc with the universal plane framebuffer refcounting. - Userspace can cope with it and e.g. Gnome already kills disconnected outputs and reconfigures the desktop automatically. And since there have been no regression reports for the i915 change from over 1 year ago I think all other DEs are also ready.

Lespiau, Damien authored
Earlier this week, there was a bit of confusion about those new capabilities, to the point I think it's better to document the intention and API contract. The comment documents the current situation: - the radeon driver returns the only valid size for the hw - i915 returns the maximun cursor size - other drivers fall back to returning 64x64 The common contract is to return a valid cursor size.

Add a new drm_crtc_init_with_planes() to allow drivers to provide specific primary and cursor planes at CRTC initialization.

When we expose non-overlay planes to userspace, they will become accessible via standard userspace plane API's. We should be able to handle the standard plane operations against primary planes in a generic way via the modeset handler. Drivers that can program primary planes more efficiently, that want to use their own primary plane structure to track additional information, or that don't have the limitations assumed by the helpers are free to provide their own implementation of some or all of these handlers. v3: Tweak kerneldoc formatting slightly to avoid ugliness v2: - Move plane helpers to a new file (drm_plane_helper.c) - Tighten checks on update handler (check for scaling, CRTC coverage, subpixel positioning) - Pass proper panning parameters to modeset interface - Disallow disabling primary plane (and thus CRTC) if other planes are still active on the CRTC. - Use a minimal format list that should work on all hardware/drivers. Drivers may call this function with a more accurate plane list to enable additional formats they can support. Signed-off-by:

After reading a nice article on LWN[1], I went back and double checked my handling of invalid-input checking. Turns out there were a couple places I had missed. Since the driver is fairly young, and the devices it supports are really only just barely usable for basic stuff (serial console) with an upstream kernel, I think we should fix this now and revert specific parts of this patch later in the unlikely event that a regression is reported.
