2006-10-14remove config.h from build no longer exists kbuild does itDave Airlie
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.
2006-10-02Fix type of second argument to spin_lock_irqsave().Michel Dänzer
2006-10-02drm_rmdraw: Declare id and idx as signed so testing for < 0 works as intended.Felix Kühling
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.
2006-09-28i915: 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.
2006-09-28i915: Bump minor for swap scheduling ioctl and secondary vblank support.Michel Dänzer
2006-09-28i915_vblank_swap: Add support for DRM_VBLANK_NEXTONMISS.Michel Dänzer
2006-09-28Only return EBUSY after we've established we need to schedule a new swap.Michel Dänzer
2006-09-28Core 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.
2006-09-28Fix 'sequence has passed' condition in i915_vblank_swap().Michel Dänzer
2006-09-28Add SAREA fileds for determining which pipe to sync window buffer swaps to.Michel Dänzer
2006-09-28Make 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.
2006-09-28DRM_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().
2006-09-28Change 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.
2006-09-28Add copyright notice.Michel Dänzer
2006-09-28i915: 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.
2006-09-28Locking and memory management fixes.Michel Dänzer
2006-09-28Export drm_get_drawable_info symbol from core.Michel Dänzer
2006-09-28Only reallocate cliprect memory if the number of cliprects changes.Michel Dänzer
Also improve diagnostic output.
2006-09-28Add 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.
2006-09-28Add 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.
2006-09-28Add support for secondary vertical blank interrupt to DRM core.Michel Dänzer

2006-09-15Use register writes instead of BITBLT_MULTI packets for buffer swap blits.Michel Dänzer
This takes up two more ring buffer entries per rectangle blitted but makes sure the blit is performed top to bottom, reducing the likelyhood of tearing.
2006-09-12drm: use radeon specific names for radeon flagsDave Airlie
2006-09-06Put the PCI device/vendor id in the drm_device_t.Eric Anholt
This helps us unbreak FreeBSD DRM from the 965 changes.
2006-08-28drm: lots of small cleanups and whitespace issues fixed upDave Airlie
remove a mach64 warning, align a lot of things from linux kernel
2006-08-26Bug #7595: Avoid u32 overflows in radeon_check_and_fixup_offset().Michel Dänzer
The overflows could cause valid offsets to get rejected under some circumstances, e.g. when the framebuffer resides at the very end of the card's address space.
2006-08-10i965 code and Linux coding style < 0Dave Airlie
smack my whitespace up.
2006-08-08Add support for Intel i965G chipsets.Alan Hourihane
This is a patch prepared by Guangdeng Liao based off of Tungsten Graphics's final code drop.
2006-07-26Revert "Make sure busmastering gets disabled on module unload."Michel Dänzer
This reverts af7b89d7246efbed7d05c38fcaa6a13c4b89db90 commit. It causes an oops on X server shutdown here, and for the reporter of bug #7629 as well.
2006-07-26Bug #7629: Fix for CHIP_IS_AGP getting 'restored' with non-AGP cardsMichel Dänzer
Commit 2a47f6bfecea5dabcbf79d5e1aaf271f50070b89 caused the CHIP_IS_AGP flag to get 'restored' with PCI(e) cards. I can't think of a way to fix this without introducing a (otherwise redundant) CHIP_IS_PCI flag.
2006-07-19Make sure busmastering gets disabled on module unload.Adam Jackson
2006-07-19Use RADEON_RB3D_DSTCACHE_CTLSTAT instead of RADEON_RB2D_DSTCACHE_CTLSTAT.Michel Dänzer
The latter seems to be a read-only mirror of the former.
2006-07-19Make sure CHIP_IS_AGP flag is set when not overriding to PCI mode.Michel Dänzer
This allows using AGP after overriding to PCI mode in a previous session without reloading the DRM.
2006-07-19When writeback isn't used, actually disable it in the hardware.Michel Dänzer
Not doing this might waste bus bandwidth or even cause memory corruption or system crashes on systems that check bus transfers. No such incident has been reported though.
2006-07-19Implement RADEON_PARAM_SCRATCH_OFFSET getparam.Michel Dänzer
When this succeeds, userspace can read the scratch register contents from the mapped writeback page directly.
2006-07-19Some debug output when the getparam ioctl is called with an unknown parameter.Michel Dänzer
2006-07-19.cvsignore -> .gitignoreMichel Dänzer
Sort the merged file, remove the redundant explicit .ko lines and add some generated symlinks.
2006-07-11Keep hashed user tokens, with the following changes:Thomas Hellstrom
32-bit physical device addresses are mapped directly to user-tokens. No duplicate maps are allowed, and the addresses are assumed to be outside of the range 0x10000000 through 0x30000000. The user-token is identical to the 32-bit physical start-address of the map. 64-bit physical device addressed are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. Other map types, like upcoming TTM maps are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. This keeps compatibility with buggy drivers, while still implementing a hashed map lookup. The SiS and via device driver major bumps are reverted.
2006-07-10Change drm Map handles to be arbitrary 32-bit hash tokens in the rangeThomas Hellstrom
0x10000000 to 0x90000000 in PAGE_SIZE increments. Implement hashed map lookups. This potentially breaks both 2D and 3D drivers. If so, the corresponding 2D and 3D driver should be fixed, and it's corresponding drm device driver should have its major bumped as soon as possible. Bump sis and via drm device driver majors. The SiS and Unichrome 3D drivers are fixed in Mesa CVS HEAD and mesa_6_4_branch.
