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.
2007-05-31i915: Add support for 965GME/GLE chip.Wang Zhenyu
2007-05-29Update a bunch of FreeBSD port code.Jung-uk Kim
Tested on r200/r300. i915 updates still remain to be done.
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.

2007-03-10i915: Only wait for pending flips before asynchronous flips again.Michel Dänzer
2007-03-09i915: Do not wait for pending flips on both pipes at the same time.Michel Dänzer
The MI_WAIT_FOR_EVENT instruction does not support waiting for several events at once, so this should fix the lockups with page flipping when both pipes are enabled.
2007-02-28i915: Eliminate dev_priv->current_page.Michel Dänzer
Always use dev_priv->sarea_priv->pf_current_page directly. This allows clients to modify it as well while they hold the HW lock, e.g. in order to sync pages between pipes.
2007-02-28i915: Only clean up page flipping when the last client goes away, not any one.Michel Dänzer
2007-02-28i915: Don't emit waits for pending flips before emitting synchronous flips.Michel Dänzer
The assumption is that synchronous flips are not isolated usually, and waiting for all of them could result in stalling the pipeline for long periods of time. Also use i915_emit_mi_flush() instead of an old-fashioned way to achieve the same effect.
2007-02-22i915: Add support for scheduled buffer swaps to be done as flips.Michel Dänzer
Unfortunately, emitting asynchronous flips during vertical blank results in tearing. So we have to wait for the previous vertical blank and emit a synchronous flip.
2007-02-19i915: Improved page flipping support, including triple buffering.Michel Dänzer
Pages are tracked independently on each pipe. Bump the minor version for 3D clients to know page flipping is usable, and bump driver date.
2007-02-19i915: Page flipping enhancements.Michel Dänzer
Leave it to the client to wait for the flip to complete when necessary, but wait for a previous flip to complete before emitting another one. This should help avoid unnecessary stalling of the ring due to pending flips. Call i915_do_cleanup_pageflip() unconditionally in preclose.
2007-02-19i915: Unify breadcrumb emission.Michel Dänzer
2007-02-07Warning fix: correct type of i915_mmio argument.Eric Anholt
2007-01-12Delay for a usec while spinning waiting for ring buffer space.Haihao Xiang
This means the loop will wait up to ~10ms for ring buffer space to become available, rather than just however long it takes to check the space 10000 times. This matches other drivers' behavior when waiting for ring buffer/fifo space.
2007-01-06i915: ARB_Occlusion_query(MMIO ioctl) support.Zou Nan hai
This adds a new ioctl for passing counter information from the chip back to applications, these counters include the data needed to perform OC.

2006-09-29i915: Add ioctl for scheduling buffer swaps at vertical blanks.Michel Dänzer
This uses the core facility to schedule a driver callback that will be called ASAP after the given vertical blank interrupt with the HW lock held. (cherry picked from 257771fa290b62d4d2ad896843cf3a207978d0bb commit)

2006-08-21i915 fence object driver implementing 2 fence object types:Thomas Hellstrom
0x00 EXE fence. Signals when command stream interpreter has reached the point where the fence was emitted. 0x01 FLUSH fence. Signals when command stream interpreter has reached the point where the fence was emitted, and all previous drawing operations have been completed and flushed. Implements busy wait (for fastest response time / high CPU) and lazy wait (User interrupt or timer driven).

2006-06-19Add i915 ioctls to configure pipes for vblank interrupt.Keith Packard
i915 vblanks can be generated from either pipe a or b, however a disabled pipe generates no interrupts. This change allows the X server to select which pipe generates vblank interrupts.
