media: saa7146: use sg_dma_len when building pgtable

2021-05-14T08:52:35+00:00

[ Upstream commit e56429b09d5e0802b86f84ec7c24025886c9f88b ]

The new AMD IOMMU DMA implementation concatenates sglist entries under
certain conditions, and because saa7146 accessed the length member
directly, it did not support this scenario.

This fixes IO_PAGE_FAULTs by using the sg_dma_len macro.

It's the only user. This also garbage collects the CONFIG_FRAME_VECTOR
symbol from all over the tree (well just one place, somehow omap media
driver still had this in its Kconfig, despite not using it).

mm/frame-vector: Use FOLL_LONGTERM

2021-01-12T13:15:17+00:00

This is used by media/videbuf2 for persistent dma mappings, not just
for a single dma operation and then freed again, so needs
FOLL_LONGTERM.

Unfortunately current pup_locked doesn't support FOLL_LONGTERM due to
locking issues. Rework the code to pull the pup path out from the
mmap_sem critical section as suggested by Jason.

By relying entirely on the vma checks in pin_user_pages and follow_pfn
(for vm_flags and vma_is_fsdax) we can also streamline the code a lot.

Note that pin_user_pages_fast is a safe replacement despite the
seeming lack of checking for vma->vm_flasg & (VM_IO | VM_PFNMAP). Such
ptes are marked with pte_mkspecial (which pup_fast rejects in the
fastpath), and only architectures supporting that support the
pin_user_pages_fast fastpath.

media: videobuf2: always call poll_wait() on queues

2021-01-04T12:12:46+00:00

do_poll()/do_select() seem to set the _qproc member of poll_table to
NULL the first time they are called on a given table, making subsequent
calls of poll_wait() on that table no-ops. This is a problem for vb2
which calls poll_wait() on the V4L2 queues' waitqueues only when a
queue-related event is requested, which may not necessarily be the case
during the first poll.

Fix this by making the call to poll_wait() happen first thing and
unconditionally in vb2_core_poll().
