2005-04-13Fix build on FreeBSD-current, thanks to jhb@.Eric Anholt
2005-02-19Merge r1.26 from FreeBSD: Now that mem(4) is a kernel module, we need toEric Anholt
depend on it.
2005-02-14Use fuword32 for DRM_GET_USER_UNCHECKED when available. May help on 64-bitEric Anholt
platforms. Submitted by: Jung-uk Kim, jkim at niksun dot com
2005-02-14Use the proper API to get PCI vendor/device number for a dev.Eric Anholt
PR: ports/76879 Submitted by: Alex, lesha at intercaf dot ru.
2005-02-13Fix bad copy'n'pastage of copyrights -- don't disclaim anything for VAEric Anholt
Linux or PI in my copyrights when I should be doing it for myself.
2005-02-13Add the first bits necessary for a port of savage to FreeBSD. More toEric Anholt
follow later.
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).
2005-02-07Restore a debugging message to DRM_DEBUG instead of DRM_ERROR.Eric Anholt
2005-02-07Remove some annoying trailing whitespace.Eric Anholt
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.

2004-12-15Use SYSCTL_ADD_OID macro instead of calling function directly.Eric Anholt
Submitted by: reffie@FreeBSD.org
2004-11-07Refine the locking of the DRM. Most significant is covering the driverEric Anholt
ioctls with dev_lock, which is a major step toward being able to remove Giant. Covers some new pieces (dev->unique*) in the core, and avoids one call down into system internals with the drm lock held, which is usually bad (FreeBSD LOR #23, #27).
2004-11-07Don't link in files which no longer exist.Eric Anholt
2004-11-07Now that the memory debug code is gone, and all 3 BSDs have M_ZERO, stopEric Anholt
using drm_alloc/drm_free in the core and instead use plain malloc/free.
2004-11-06Add the drm Makefile and update .cvsignores.Eric Anholt
2004-11-06Convert more drivers for bsd-core, moving the ioctl definitions to sharedEric Anholt
code. Remove the "drv" from sisdrv, as it's unnecessary. Use the drm_pci functions in i915 instead of per-os implementations of the same. Avoid whitespace within fields in drm_pciids.txt (one of the r300 definitions), since it breaks the bsd pciids script. Tested on sis, mga, r128. i915 needs more work.
2004-11-06Remove some core stuff that ended up being unnecessary.Eric Anholt
2004-11-06Get r128 basically working: Hook up the driver's dma ioctl, use the properEric Anholt
offset into the driver ioctl array, and don't make the ctx bitmap conditional.
2004-11-06Move the lock/unlock ioctls to a more logical place, in drm_lock.c.Eric Anholt
2004-11-06Connect up r128_ioctls in driver config.Eric Anholt
2004-11-06Hook the debug output up to a sysctl, so you can choose to enable atEric Anholt
runtime.
2004-11-06Add file missed in last commit: Commit first pieces of port to OpenBSD,Eric Anholt
done by Martin Lexa (martin at martinlexa dot cz). Now that we've got porting for all three major BSDs (and the fourth being very similar to FreeBSD), move the mostly-duplication drm_os_* files into drmP.h. Remove some cruft from linux heritage and from pieces of the DRM that have since been removed. Note that things are still not quite working for even FreeBSD, but these are first steps at cleanup, and just a WIP checkpoint.

2004-11-06Remove the vestiges of the memory-debug code.Eric Anholt
2004-11-06Commit WIP of BSD conversion to core model. Compiles for r128, radeon, butEric Anholt
doesn't run yet. Moves the ioctl definitions for these two drivers back to the shared code -- they aren't OS-specific.
2004-08-24This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:Erdi Chen
DRM_IOCTL_VIA_DMA_INIT DRM_IOCTL_VIA_CMDBUFFER DRM_IOCTL_VIA_FLUSH The first ioctl sets up an area in AGP memory that will be used as the ring buffer. The second ioctl copies a command buffer from user space memory to the ring buffer. The third ioctl waits for engine idle until it returns. The motivation for this patch is to avoid the wait for engine idle call before each buffer flush in the current DRI driver. With this patch, the DRI driver can continue to flush its buffer as long as there is free space in the ring buffer. This patch adds an additional copy operation on the command buffer. This buffer copying is necessary to support multiple DRI clients rendering simultaneously. Otherwise, more CPU time will be spent in the busy loop waiting for engine idle between DRI context switch. Even in the single client case, the tradeoff is reasonable in comparision to the kernel call to check for free buffer space for the client to render directly to the ring buffer.
