      drm: radeon: Use surface for PCI GART table. · 6abf6bb0
      由 David Miller 提交于 
      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.

      The address needs to be a GART relative address, rather than a PCI
DMA address.

      drm: radeon: Fix ring_rptr accesses. · b07fa022
      由 David Miller 提交于 
      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.

      drm: Make drm_local_map use a resource_size_t offset · 41c2e75e
      由 Benjamin Herrenschmidt 提交于 
      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.

      drm/radeon: map registers at load time · 78538bf1
      由 Dave Airlie 提交于 
      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.

Fixes (at least partially) kernel bz #11891.

      drm: reorganise drm tree to be more future proof. · c0e09200
      由 Dave Airlie 提交于 
      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.
