2006-10-12More work on the context switch code. Still doesn't work. I'm mostly ↵Stephane Marchesin
convinced it's an initialization issue.
2006-10-11Big update:Thomas Hellstrom
Adapt for new functions in the 2.6.19 kernel. Remove the ability to have multiple regions in one TTM. This simplifies a lot of code. Remove the ability to access TTMs from user space. We don't need it anymore without ttm regions. Don't change caching policy for evicted buffers. Instead change it only when the buffer is accessed by the CPU (on the first page fault). This tremendously speeds up eviction rates. Current code is safe for kernels <= 2.6.14. Should also be OK with 2.6.19 and above.
2006-10-11Context switching work.Stephane Marchesin
Added preliminary support for context switches (triggers the interrupts, but hangs after the switch ; something's not quite right yet). Removed the PFIFO_REINIT ioctl. I hope it's that a good idea... Requires the upcoming commit to the DDX.
2006-10-10only allow specific type-3 packets to pass the verifier instead of all for ↵Roland Scheidegger
r100/r200 as others might be unsafe (r300 already does this), and add checking for these we need but aren't safe. Check the RADEON_CP_INDX_BUFFER packet on both r200 and r300 as it isn't safe neither.
2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #4.George Sapountzis
mach64_state.c: convert the DRM_MACH64_BLIT ioctl to submit a pointer to user-space memory rather than a DMA buffer index, similar to DRM_MACH64_VERTEX. This change allows the DDX to map the DMA buffers read-only and eliminate a security problem where a client can alter the contents of the DMA buffer after submission to the DRM. This change also affects the DRI/DRM interface. Performace-wise, it basically affects PCI mode where I get a ~12% speedup for some Mesa demos I tested. This is mainly due to eliminating an ioctl for allocating the DMA buffer. mach64_dma.c: move the responsibility for allocating memory for the DMA ring in PCI mode to the DDX. This change affects the DDX/DRM interface and unifies a couple of PCI/AGP code paths for ring memory in the DRM. Bump the mach64 DRM version major and date.
2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #3.George Sapountzis
Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional flag is needed, since PCI DMA buffers do not have an associated map.
2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #2.George Sapountzis
Factor out from mach64_dma_dispatch_vertex() the code to reclaim an unsed buffer, in preperation for using it in mach64_dma_dispatch_blit() also.
2006-10-02Bug 6242: [mach64] Use private DMA buffers, part #1.George Sapountzis
Factor out from mach64_freelist_get() the code to reclaim a completed buffer, this is to improve readability for me.
2006-10-02Bug 6209: [mach64] AGP DMA buffers not mapped correctly.George Sapountzis
Map the DMA buffers from the same linear address as the vertex bufs. If dev->agp_buffer_token is not set, mach64 drm maps the DMA buffers from linear address 0x0.

2006-09-29Bump driver date.Thomas Hellstrom
2006-09-29i915: Only schedule vblank tasklet if there are scheduled swaps pending.Michel Dänzer
This fixes issues on X server startup with versions of xf86-video-intel that enable the IRQ before they have a context ID. (cherry picked from 7af93dd9849442270ec89cb4bbeef5bfd4f9e424 commit)
2006-09-29i915: Only initialize IRQ fields in postinstall, not the PIPE_SET ioctl.Michel Dänzer
Some other minor changes in preparation for actually disabling user interrupts.
2006-09-29i915: Bump minor again to differentiate from vsync changes.Michel Dänzer
2006-09-29i915: Avoid mis-counting vblank interrupts when they're only enabled for pipe A.Michel Dänzer
It looks like 'after a while', I915REG_INT_IDENTITY_R for some reason always has VSYNC_PIPEB_FLAG set in the interrupt handler, even though pipe B is disabled. So we only increase dev->vbl_received if the corresponding bit is also set in dev->vblank_pipe. (cherry picked from 881ba569929ceafd42e3c86228b0172099083d1d commit)

2006-09-29Core vsync: Add flag DRM_VBLANK_NEXTONMISS.Michel Dänzer
When this flag is set and the target sequence is missed, wait for the next vertical blank instead of returning immediately. (cherry picked from 89e323e4900af84cc33219ad24eb0b435a039d23 commit)
2006-09-29Fix 'sequence has passed' condition in i915_vblank_swap().Michel Dänzer

2006-09-29Add SAREA fileds for determining which pipe to sync window buffer swaps to.Michel Dänzer
(cherry picked from c2bdb76814755c9ac6e66a8815f23af0fe4f3a91 commit)
2006-09-29Make handling of dev_priv->vblank_pipe more robust.Michel Dänzer
Initialize it to default value if it hasn't been set by the X server yet. In i915_vblank_pipe_set(), only update dev_priv->vblank_pipe and call i915_enable_interrupt() if the argument passed from userspace is valid to avoid corrupting dev_priv->vblank_pipe on invalid arguments. (cherry picked from 87c57cba1a70221fc570b253bf3b24682ef6b894 commit)
2006-09-29DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead of pipe number.Michel Dänzer
Handle relative as well as absolute target sequence numbers. Return error if target sequence has already passed, so userspace can deal with this situation as it sees fit. On success, return the sequence number of the vertical blank when the buffer swap is expected to take place. Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want to use ioctl() instead of drmCommandWriteRead(). (cherry picked from d5a0f107511e128658e2d5e15bd7e6215c507f29 commit)
2006-09-29Change first valid DRM drawable ID to be 1 instead of 0.Michel Dänzer
This makes it easier for userspace to know when it needs to allocate an ID. Also free drawable information memory when it's no longer needed. (cherry picked from df7551ef7334d728ec0371423661bb403d3e270a commit)

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)

2006-09-29Add support for tracking drawable information to coreMichel Dänzer
Actually make the existing ioctls for adding and removing drawables do something useful, and add another ioctl for the X server to update drawable information. The only kind of drawable information tracked so far is cliprects. (cherry picked from 29598e5253ff5c085ccf63580fd24b84db848424 commit)
2006-09-29Add support for secondary vertical blank interrupt to i915 driver.Michel Dänzer
When the vertical blank interrupt is enabled for both pipes, pipe A is considered primary and pipe B secondary. When it's only enabled for one pipe, it's always considered primary for backwards compatibility. (cherry picked from 0c7d7f43610f705e8536a949cf2407efaa5ec217 commit)
