2005-03-07Tracked down random lockups related to command DMA that occurred in Quake3Felix Kuehling
after ~5min: buffer aging was subtly broken. Part of this may have also affected vertex DMA buffer aging and client-side texture heap aging, though with less fatal consequences. Bumped minor version and driver date.
2005-03-07minor pointer cast typoDave Airlie
2005-03-06Added support for command DMA on Savage4-based hardware. UnfortunatelyFelix Kuehling
command and vertex DMA don't work at the same time. Command DMA performance is superior and works with all vertex formats. Bumped minor version and driver date.
2005-03-04add some idct type 3 packets for referenceDave Airlie
2005-02-23Use wrap counter to extend 16-bit hardware event tags to 32-bit logicalFelix Kuehling
event counters in the SAVAGE_EVENT_EMIT/WAIT ioctls. This is needed for reliable client-side texture heap aging. Slightly simplified DMA buffer aging while at it. Bumped minor version and driver date.
2005-02-20Fix VIA K8M800 PCI ID.Thomas Hellstrom
2005-02-19Fix a couple of gcc warnings in DRM_INFOs.Eric Anholt
2005-02-18fd.o bug #2576: Add support for ATI RN50/ES1000. (ATI Technologies Inc.)Michel Daenzer
2005-02-14Initialize kbuf to NULL to quiet the compiler about uninit variablesEric Anholt
(wasn't an issue). Don't forget to free kbuf if the copyin fails.
2005-02-13Fixed Futex release bug. Bumped driver date and patchlevel.Thomas Hellstrom
2005-02-10add support for texture micro tiling on radeon/r200. Add support for r100Roland Scheidegger
cube maps (since it also requires a version bump) at the same time.
2005-02-08Close a race which could allow for privilege escalation by users with DRIEric Anholt
privileges on Radeon hardware. Essentially, a malicious program could submit a packet containing an offset (possibly in main memory) to be rendered from/to, while a separate thread switched that offset in userspace rapidly between a valid value and an invalid one. radeon_check_and_fixup_offset() would pull the offset in from user space, check it, and spit it back out to user space to be copied in later by the emit code. It would sometimes catch the bad value, but sometimes the malicious program could modify it after the check and get an invalid offset rendered from/to. Fix this by allocating a temporary buffer and copying the data in at once. While here, make the cliprects stuff not do the VERIFYAREA_READ and COPY_FROM_USER_UNCHECKED gymnastics, avoiding a lock order reversal on FreeBSD. Performance impact is negligible -- no difference on r200 to ~1% improvement on rv200 in quake3 tests (P4 1Ghz, demofour at 1024x768, n=4 or 5).
2005-02-07fix agp detection on linuxDave Airlie
2005-02-05- Implement drm_initmap, and extend it with the resource number to helpEric Anholt
FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff doesn't need to be in shared code. - Fix mach64 build by using __DECONST to work around passing a const pointer to useracc, which is unfortunately not marked const. - Get rid of a lot of maplist code by not having dev->maplist be a pointer, and by sticking the link entries directly in drm_local_map_t rather than having a separate structure for the linked list. - Factor out map uninit and removal into its own routine, rather than duplicating in both drm_takedown() and drm_rmmap(). - Hook up more driver functions, and correct FreeBSD-specific bits of radeon_cp.c, making radeon work. - Baby steps towards using bus_space as we should.

2005-01-16The patch makes drmAddBufs/drmMapBufs can handle buffers in video memoryDave Airlie
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP memory but uses video memory. From: austinyuan@viatech.com.cn (fd.o bug 1668) Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-01-16Fixed a bug that prevented the driver from ever emitting triangle strips orFelix Kuehling
fans. Bumped patchlevel and driver date.
2005-01-15Setup MTRRs for frame buffer and aperture manually on Savage3D andFelix Kuehling
Savage4-based cards. Automatic setup in drm_initmap doesn't work due to the weird alignment and size of the aperture.
2005-01-10Only try to find the agp_buffer_map if dma_type is AGP. This is all that'sFelix Kuehling
needed on the DRM side to support PCI Savages. Bumped patch level and driver date.
2005-01-09Improved workaround for Savage3D DMA lockup to emit NOPs only before theFelix Kuehling
first indexed drawing command of a cmdbuf or if a wait command was emitted since the last indexed drawing command.
2005-01-08Fixed off-by-one error in savage_bci_wait_fifo_shadow.Felix Kuehling
2005-01-07via updates: moved the verifier state struct to dev_priv. Implemented AGPThomas Hellstrom

2005-01-06Add i915GM support Add resume functionality (must be used with later DDX)Alan Hourihane
Bump to 1.2
2005-01-06via DRM: Updated the verifier to check the vertex lists more thorough. ThisThomas Hellstrom
should hopefully stop it from getting out of sync. The PCI command parser is still not updated.
2005-01-053D scissor regs are now managed by the DRM to iterate over clip rectsFelix Kuehling
passed to the cmdbuf ioctl (try xeyes on top of glxgears ;-) Tightened the texture state check Bumped Savage DRM version to 2.1.0 so that DRI driver can (theoretically) depend on the DRM to manage the scissor registers
2005-01-05Bumped driver date and minor version.Thomas Hellstrom
2005-01-05VIA update:Thomas Hellstrom
Release video futexes when context is destroyed (This was previously done by the X server). Added New Unichrome Pro VIDEO DMA commands to the verifier. Added Quiescent heavyweight lock mode.
2005-01-05Fixed the DMA buffer age test. Should fix occasional "soft" lockups. BumpedFelix Kuehling
patch level and driver date.
2005-01-01Completeley rewritten Savage DRM which can be considered secure (moduloFelix Kuehling
implementation errors). Direct hardware (MMIO, BCI) access is no longer needed in the Mesa driver. Bumped version to 2.0.0. Corresponding changes to the DDX and Mesa drivers are being committed.
2005-01-01Added a new DRM map type _DRM_CONSISTENT for consistent PCI memory. It usesFelix Kuehling
drm_pci_alloc/free for allocating/freeing the memory. Only implemented in the Linux DRM so far.
2004-12-31VIA DRM: verifier: Added verbose palette error reporting, and support forThomas Hellstrom
stipple palettes together with rudimentary checks for texture palette sizes. other: Bumped version patchlevel and driver date.

DRM_IOCTL_VIA_DMA_INIT IOCTL. Bumped patchlevel and driver date. XFree86 bug: 2119
2004-12-20Copy HC_ParaType_Auto change to shared-core. Bump version numbers andKeith Whitwell
dates.
2004-12-19via changes: Fixed typecasting bug in via_dma.c, and possible short-circuitThomas Hellstrom
bug in the cmdbuf_size ioctl. Modified ring-buffer jump code AGAIN, due to new oddities discovered on the Unichrome Pro with faster processors. Bumped patchlevel and driver date.
2004-12-13VIA drm updates:Thomas Hellstrom
1. Improved security check of AGP texture adresses. 2. Hopefully last fix of ring-buffer jump oddities. 3. Added ioctl to check available space and command regulator lag in ring-buffer. This is needed for 3D application responsiveness.
