gpu: ion: DRA7: ensure TILER 2d mappings are shared device

2013-07-26T21:00:49+00:00

Write combined mappings are not supported for TILER 2D on DRA7
similar  to OMAP5 due to h/w issue. So, shared mappings should
be used. Added the check which was missing for DRA7.

ARM: dts: DRA7/OMAP5: reserve carveout buffers & fix carveout size

2013-07-26T21:00:24+00:00

Carveout buffers were initialized but not reserved for
DRA7. This patch adds the missing memreserves without
which there could be data corruption in highmem region.

In addition, the carveout size for TILER secure heap was programmed
wrongly to 96MB whereas it should have been 81 MB. This patch
fixes this and re-adjusts the carveout base addresses.

gpu: ion: fix omap_ion_share_fd_to_buffers api

2013-07-26T20:59:45+00:00

the output value from ion_share_dma_buf is a dma buf fd
buffers array was filled mistakenly as the code was ported
from k3.4 where the equivalent function ion_share used to
return pointer to ion_buffer. updated the code to upref
using ion_share_dma_buf() and get the handle to buffer using
ion_handle_buffer().

gpu: ion: omap: add checks for carveout addresses and sizes

2013-07-26T20:59:21+00:00

This patch adds sanity checks on the carveout and size parameters
read from the device tree file and returns error. It also checks
if the device tree is populated and returns error accordingly.

gpu: ion: omap: Fix TILER secure heap base address

2013-07-26T20:58:56+00:00

Access to ION TILER buffers were resulting in data aborts
because of incorrect heap base address initialization.
The omap_ion_heap_tiler_base variable was not being
initialized. With this patch the ION tests pass.

gpu: ion: omap: re-populate flags parameters into buffer

2013-07-26T20:58:27+00:00

Since the flags function param of omap_tiler_heap_allocate
is used to pass the omap_tiler_info struct, pass the
actual flags param from the client inside omap_tiler_info
struct and re-populate it into the buffer struct.
