2011-02-07drm: rework PCI/platform driver interface.Dave Airlie

2010-03-01drm/radeon: r100/r200 ums: block ability for userspace app to trash 0 page ↵Dave Airlie
and beyond radeon's have a special ability to passthrough writes in their internal memory space directly to PCI, this ability means that if some of the internal surfaces like the depth buffer point at 0x0, any writes to these will go directly to RAM at 0x0 via PCI busmastering. Now mesa used to always emit clears after emitting state, since the radeon mesa driver was refactored a year or more ago, it was found it could generate a clear request without ever sending any setup state to the card. So the clear would attempt to clear the depth buffer at 0x0, which would overwrite main memory at this point. fs corruption ensues. Also once one app did this correctly, it would never get set back to 0 making this messy to reproduce. The kernel should block this from happening as mesa runs without privs, though it does require the user be connected to the current running X session. This patch implements a check to make sure the depth offset has been set before a depth clear occurs and if it finds one it prints a warning and ignores the depth clear request. There is also a mesa fix to avoid sending the badness going into mesa. This only affects r100/r200 GPUs in user modesetting mode. Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-03-13drm: radeon: Use surface for PCI GART table.David Miller
This allocates a physical surface for the PCI GART table, this way no matter what other surface configurations exist the GART table will always be seen by the hardware properly. We encode the file pointer of the virtual surface allocate using a special cookie value, called PCIGART_FILE_PRIV. On the last close, we release that surface. Just to be doubly safe, we run the pcigart table setup with the main surface control register clear. Based upon ideas from David Airlie and Ben Benjamin Herrenschmidt. Signed-off-by: David S.

2009-03-13drm: radeon: Fix ring_rptr accesses.David Miller
The memory behind ring_rptr can either be in ioremapped memory or a vmalloc() normal kernel memory buffer. However, the code unconditionally uses DRM_{READ,WRITE}32() (and thus readl() and writel()) to access it. Basically, if RADEON_IS_AGP then it's ioremap()'d memory else it's vmalloc'd memory. Adjust all of the ring_rptr access code as needed. While we're here, kill the 'scratch' pointer in drm_radeon_private. It's only used in the one place where it is initialized. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Dave Airlie <airlied@linux.ie>
2009-03-13drm: Make drm_local_map use a resource_size_t offsetBenjamin Herrenschmidt
This changes drm_local_map to use a resource_size for its "offset" member instead of an unsigned long, thus allowing 32-bit machines with a >32-bit physical address space to be able to store there their register or framebuffer addresses when those are above 4G, such as when using a PCI video card on a recent AMCC 440 SoC. This patch isn't as "trivial" as it sounds: A few functions needed to have some unsigned long/int changed to resource_size_t and a few printk's had to be adjusted. But also, because userspace isn't capable of passing such offsets, I had to modify drm_find_matching_map() to ignore the offset passed in for maps of type _DRM_FRAMEBUFFER or _DRM_REGISTERS. If we ever support multiple _DRM_FRAMEBUFFER or _DRM_REGISTERS maps for a given device, we might have to change that trick, but I don't think that happens on any current driver.

2008-12-29drm: move to kref per-master structures.Dave Airlie
This is step one towards having multiple masters sharing a drm device in order to get fast-user-switching to work. It splits out the information associated with the drm master into a separate kref counted structure, and allocates this when a master opens the device node. It also allows the current master to abdicate (say while VT switched), and a new master to take over the hardware. It moves the Intel and radeon drivers to using the sarea from within the new master structures. Signed-off-by: Dave Airlie <airlied@redhat.com>

2008-11-11drm/radeon: map registers at load timeDave Airlie
Now that the radeon driver has suspend/resume functions, it needs to map its registers at load time or it will likely crash if a suspend operation occurs before the driver has been initialized. This patch moves the register mapping code from firstopen to load and makes the mapping into a _DRM_DRIVER one so that the core won't remove it at lastclose time.

2008-10-18drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes
Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
