hi all,
i see the drm kernel source code, for SCATTER MEMORY, use vmalloc_32() to
alloce some pages, and put
them into sglist table in drm_scatter.c. and in drm_mmap_locked(), why it
not call *remap_vmalloc_range() to
remap the pages to vm_area for mmap? how it remap pages(that memory using
vmalloc_32() to alloc) to vm_area?
so i am puzzle how the mmap() is work for sg? would someone give it more
details? Thanks.
Best
Figo
