2006-10-18Remove stray softlink.Thomas Hellstrom
2006-10-18Avoid driver-specific AGP user-populated types, since we don't know what AGPThomas Hellstrom
driver we're on. Avoid global cache flushes before inserting pages. In general, they are never mapped, and not accessed through the kernel map, so a cache flush should not be necessary. The exception is pages that are bound cached. We might need a cache flush for those.
2006-10-17Remove some debugging messages.Thomas Hellstrom
2006-10-17Remove max number of locked pages check and call, sinceThomas Hellstrom
that is now handled by the memory accounting.
2006-10-17Lindent.Thomas Hellstrom
2006-10-17Add vma list memory usage to memory accounting.Thomas Hellstrom
Use byte unit for /proc printout of memory usage for small sizes to be able to detect memory allocation bugs more easily.
2006-10-17Add memory usage accounting to avoid DOS problems.Thomas Hellstrom
2006-10-17Implement mm_lock and mm_unlock functions.Thomas Hellstrom
The mm_lock function is used when leaving vt. It evicts _all_ buffers. Buffers with the DRM_BO_NO_MOVE attribute set will be guaranteed to get the same offset when / if they are rebound.
2006-10-17Remove the memory manager parameter from the put_block function, as thisThomas Hellstrom
makes the client code a lot cleaner. Prepare buffer manager for lock and unlock calls.

Fix up init and destruction code.

2006-10-12Bugfixes.Thomas Hellstrom
2006-10-12Simplify the AGP backend interface somewhat.Thomas Hellstrom
Fix buffer bound caching policy changing, Allow on-the-fly changing of caching policy on bound buffers if the hardware supports it. Allow drivers to use driver-specific AGP memory types for TTM AGP pages. Will make AGP drivers much easier to migrate.
2006-10-11Compatibility code for 2.6.15-2.6.18. It is ugly but a little comfort is thatThomas Hellstrom
it will go away in the mainstream kernel. Some bugfixes, mainly in error paths.
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.
2006-10-10Use a nopage-based approach to fault in pfns.Thomas Hellstrom
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.

2006-10-02Make the user_token 44-bit for TTMs, and have them occupy a unique file spaceThomas Hellstrom
starting at 0x00100000000. This will hopefully allow us to use unmap_mapping_range(). Note that user-space will need 64-bit file offset support.
2006-10-02Add a buffer object manager for TTM maps.Thomas Hellstrom

2006-10-02drm_rmdraw: Declare id and idx as signed so testing for < 0 works as intended.Felix Kühling

2006-10-02Make locked tasklet handling more robust.Michel Dänzer
Initialize the spinlock unconditionally when struct drm_device is filled in, and return early in drm_locked_tasklet() if the driver doesn't support IRQs.

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)
2006-09-29i915: Bump minor for swap scheduling ioctl and secondary vblank support.Michel Dänzer

2006-09-29i915_vblank_swap: Add support for DRM_VBLANK_NEXTONMISS.Michel Dänzer
(cherry picked from 0356fe260dcf80f6d2d20e3384f2a1f4ee7f5b30 commit)
2006-09-29Only return EBUSY after we've established we need to schedule a new swap.Michel Dänzer
(cherry picked from 50a0284a61d4415c0ebdb02decee76ef3115007a commit)
2006-09-29Core vsync: Don't clobber target sequence number when scheduling signal.Michel Dänzer
It looks like this would have caused signals to always get sent on the next vertical blank, regardless of the sequence number. (cherry picked from cf6b2c5299e9be3542d4deddfd05d5811f11d2ef 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
(cherry picked from 7f09f957d9a61ac107f8fd29128d7899a3e8a228 commit)
2006-09-29Add SAREA fileds for determining which pipe to sync window buffer swaps to.Michel Dänzer
(cherry picked from c2bdb76814755c9ac6e66a8815f23af0fe4f3a91 commit)
2006-09-29Add definition of DRM_VBLANK_SECONDARY.Michel Dänzer
(cherry picked from 84b38b63f05e04ade8b1ddfb770047fd86de0d64 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)
