* drm: Add generic multipart buffer.Pauli Nieminen2010-02-232-1/+185
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating multiple pages of memory for data that is coming from user space may fail. To fix memory allocation failures the buffer object should be split to multiple independ pages. drm buffer provides generic interface to copy and process large data arrays from user space. Interface includes allocation and free functions to allocate the buffer object and data storage pages. All access operations are performed relative to a internal pointer which is advanced with drm_buffer_advance function. The buffer can be accessed using drm_buffer_pointer_to_XXX functions if it is known that requested object doesn't split over a page boundary. These functions don't do any error checking to maximize performance. If there is large object which could be split there is special drm_buffer_read_object function. drm_buffer_read_object takes a pointer as argument which is used as temporary store for data if it is split over boundary in the buffer.

* drm/radeon/kms: simplify memory controller setup V2Jerome Glisse2010-02-1818-424/+301
| | | | | | | | | | | | | | | | | | | | | | | | | Get rid of _location and use _start/_end also simplify the computation of vram_start|end & gtt_start|end. For R1XX-R2XX we place VRAM at the same address of PCI aperture, those GPU shouldn't have much memory and seems to behave better when setup that way. For R3XX and newer we place VRAM at 0. For R6XX-R7XX AGP we place VRAM before or after AGP aperture this might limit to limit the VRAM size but it's very unlikely. For IGP we don't change the VRAM placement. Tested on (compiz,quake3,suspend/resume): PCI/PCIE:RV280,R420,RV515,RV570,RV610,RV710 AGP:RV100,RV280,R420,RV350,RV620(RPB*),RV730 IGP:RS480(RPB*),RS690,RS780(RPB*),RS880 RPB: resume previously broken V2 correct commit message to reflect more accurately the bug and move VRAM placement to 0 for most of the GPU to avoid limiting VRAM.

* drm/radeon: Add asic hook for dma copy to r200 cards.Pauli Nieminen2010-02-184-59/+104
| | | | | | | | | | | | | | | | | r200 cards have dma engine which can be used to tranfer data between vram and system memory. r300 dma engine registers match r200 dma engine. Enabling dma copy for r200 is simple as hooking r200 asic to already existing function r300_copy_dma. Rename r300_dma_copy to r200_dma_copyto reflect that supports starts from r200 cards. v2: Created a new asic object for r200 cards.

* drm/radeon/kms: fix indirect buffer management V2Jerome Glisse2010-02-163-72/+45
| | | | | | | | | | | | | | | | | | | | | | | | There is 3 different distinct states for an indirect buffer (IB) : 1- free with no fence 2- free with a fence 3- non free (fence doesn't matter) Previous code mixed case 2 & 3 in a single one leading to possible catastrophique failure. This patch rework the handling and properly separate each case. So when you get ib we set the ib as non free and fence status doesn't matter. Fence become active (ie has a meaning for the ib code) once the ib is scheduled or free. This patch also get rid of the alloc bitmap as it was overkill, we know go through IB pool list like in a ring buffer as the oldest IB is the first one the will be free. Fix : https://bugs.freedesktop.org/show_bug.cgi?id=26438 and likely other bugs.

| | | | | | | | | | | | | | this uses a new entrypoint to invalidate gart entries instead of using 0. Changed to rather than pointing to 0 address point empty entry to dummy page. This might help to avoid hard lockup if for some wrong reasons GPU try to access unmapped GART entry. I'm not 100% sure this is going to work, we probably need to allocate a dummy page and point all the GTT entries at it similiar to what AGP does. but we can test this first I suppose.

* drm/radeon/kms: r600/r700 command stream checkerJerome Glisse2010-02-119-129/+2058
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add cs checker to r600/r700 hw. Command stream checking will rewrite some of the cs value in order to restrict GPU access to BO size. This doesn't break old userspace but just enforce safe value. It should break any things that was using the r600/r700 cs ioctl to do forbidden things (malicious software), though we are not aware of such things. Here is the list of thing we check : - enforcing resource size - enforcing color buffer slice tile max, will restrict cb access - enforcing db buffer slice tile max, will restrict db access We don't check for shader bigger than the BO in which they are supposed to be, such use would lead to GPU lockup and is harmless from security POV, as far as we can tell (note that even checking for this wouldn't prevent someone to write bogus shader that lead to lockup). This patch has received as much testing as humanly possible with old userspace to check that it didn't break such configuration. However not all the applications out there were tested, thus it might broke some odd, rare applications.

Hooking it up will require reworking the the current power state selection code and will be handled in a future patch.
