hwmem: Add peak memory usage in debugfs prints

2012-05-22T09:03:43+00:00

When doing cat debugfs/cona/hwmem_allocs you will now see current memory usage, Max amount of hwmem memory used after boot, and size of biggest free block.

HWMEM: Break out allocator

2012-05-22T09:03:43+00:00

Break out allocator in order to be able to run it in multiple instances ie support multiple regions. Multiple regions can be used to battle fragmentation by letting clients allocating in a non fragmenting way allocate from their own region. For STE this will probably mean letting camera/video have their own region. A positive side effect is that we can use HWMEM as an allocator for SRAM if we want to.

HWMEM: Alloc kernel vaddrs on boot

2012-05-22T09:03:42+00:00

By allocating all the kernel virtual addresses on boot fragmentation of the vmalloc area can not cause HWMEM allocs to fail.

HWMEM: Reset ref count in clean_alloc

2012-05-22T09:03:42+00:00

When hwmem_alloc fails to alloc virtual memory for the kernel mapping it will call clean_alloc with a non-zero ref count. If the ref count is not reset in that case we will leak HWMEM memory.

HWMEM: Make user space include linux/types.h

2012-05-22T09:03:42+00:00

__x32 are defined in linux/types.h which is therefore needed in user space also. This patch also adds the uncached flag when allocating the FB to ensure we don't get a cached FB.
