2007-12-15Document drm_bo_handle_validate. Match drm_bo_do_validate parameter order.Keith Packard
Document parameters and usage for drm_bo_handle_validate. Change parameter order to match drm_bo_do_validate (fence_class has been moved to after flags, hint and mask values). Existing users of this function have been changed, but out-of-tree users must be modified separately.

2007-12-11i915: wait for buffer idle before writing relocationsKeith Packard
When writing a relocation entry, make sure the target buffer is idle, otherwise the GPU may see inconsistent data.
2007-12-11Allow relocation to be skipped when buffers don't move.Keith Packard
One of the costs of superioctl has been the need to perform relocations inside the kernel. The cost of mapping the buffers to the CPU and writing data is fairly high, especially if those buffers have been mapped and read by the GPU. If we assume that buffers don't move around very often, we can have the client compute the relocations itself using the previous GPU address. When that object doesn't move, the kernel can skip computing and writing the updated data. Here's a patch which adds a new field to struct drm_bo_info_req called 'presumed_offset', and a new DRM_BO_HINT_PRESUMED_OFFSET that is set when this field has been filled in by the client. There are two separate optimizations performed when the presumed_offset is correct: 1. i915_exec_reloc checks to see if all previous buffer offsets were guessed correctly. If so, there's no need for it to look at *any* of the relocations for a buffer. When this happens, it skips the whole relocation process, simply returning success. 2. i915_apply_reloc checks to see if the target buffer offset was guessed correctly. If so, it skips mapping the relocatee, computing the relocation and writing the value. If no relocations are needed, the relocatee should never be mapped to the CPU, and so the kernel shouldn't need to wait for any fences to pass.

This field isn't touched or read by any other code in the stack so it's time to retire these last few references.

2007-10-26i915: suspend/resume supportJesse Barnes
Add suspend/resume support to the i915 driver. Moves some of the initialization into the driver load routine, and fixes up places where we assumed no dev_private existed in some of the cleanup paths. This allows us to suspend/resume properly even if X isn't running.

2007-10-12i915: add superioctl support to i915Dave Airlie
This adds the initial i915 superioctl interface. The interface should be sufficent even if the implementation may needs fixes/optimisations internally in the drm wrt caching etc.
2007-09-28Revert drm_i915_flip_t braindamageJesse Barnes
I should not have renamed this field. I should not have renamed this field. I should not have renamed this field. On the plus side, it was at least binary compatible.
2007-09-11Disambiguate planes & pipes for swap operationsJesse Barnes
This mod makes the SAREA track plane to pipe mappings and corrects the name of the plane info variables (they were mislabeled as pipe info since until now all code assumed a direct mapping between planes and pipes). It also updates the flip ioctl argument to take a set of planes rather than pipes, since planes are flipped while pipes generate vblank events.

2007-07-20Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt
The data is now in kernel space, copied in/out as appropriate according to the This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DRM is lost.
2007-07-20Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.
2007-07-20Remove DRM_ERR OS macro.Eric Anholt
This was used to make all ioctl handlers return -errno on linux and errno on *BSD. Instead, just return -errno in shared code, and flip sign on return from shared code to *BSD code.

2007-06-05Add support for the G33, Q33, and Q35 chipsets.Wang Zhenyu
These require that the status page be referenced by a pointer in GTT, rather than phsyical memory. So, we have the X Server allocate that memory and tell us the address, instead.

2007-05-10Allow vblank interrupts to remain disabled across VT switch.Keith Packard
i915_driver_irq_postinstall was forcing vblank interrupts to pipe A when called with vblank interrupts disabled. This caused vblank interrupts to be accidentally re-enabled when VT switching the X server. Instead, start the driver with vblank interrupts enabled on pipe A to support older X servers, but then leave control over the state to the X server if it is able to do so.
