2006-10-26Add improved alignment functionality to the core memory manager.Thomas Hellstrom
This makes an allocated block actually align itself and returns any wasted space to the manager. Also add some functions to grow and shrink the managed area. This will be used in the future to manage the buffer object swap cache.

2006-10-21The CPU cache must be flushed _before_ we start modifying the kernel map ptes,Thomas Hellstrom
otherwise data will be missing, which becomes apparent when the kernel evicts batch buffers which are likely to be written into in the evicted state, and then rebound to the AGP aperture. This means we cannot rely on the AGP module to flush the cache for us.

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.

that is now handled by the memory accounting.

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
2006-10-18Remove hack which delays activation of a additional channel. The previously ↵Ben Skeggs
active channel's state is saved to RAMFC before PFIFO gets clobbered.
2006-10-18Oops, we have more than 4 subchannels..Ben Skeggs
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.

2006-10-17NV40: *Now* fifo ctx switching works for me..Ben Skeggs
Ok, I lied before.. it was a fluke it worked and required magic to repeat it.. It actually helps to fill in RAMFC entries in the correct place. The code also clears RAMIN entirely instead of just the hash-table.

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.
2006-10-12More work on the context switch code. Still doesn't work. I'm mostly ↵Stephane Marchesin
convinced it's an initialization issue.
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.
2006-10-11Context 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.
2006-10-10Use a nopage-based approach to fault in pfns.Thomas Hellstrom

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.
2006-10-03Get rid of all ugly PTE hacks.Thomas Hellstrom
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.
