accelerates 2D graphics operations, such as point/line drawing, image
scaling, rotation, BitBLT, alpha blending and image blur/sharpness
The driver supports various operations from the rendering pipeline.
- copy
- fast solid color fill
- rotation
- flip
- alpha blending
The code in rga-hw.c is used to configure regs according to operations
The code in rga-buf.c is used to create private mmu table for RGA.

x86/mm: Flush more aggressively in lazy TLB mode
Since commit:
94b1b03b519b ("x86/mm: Rework lazy TLB mode and TLB freshness tracking")
x86's lazy TLB mode has been all the way lazy: when running a kernel thread
(including the idle thread), the kernel keeps using the last user mm's
page tables without attempting to maintain user TLB coherence at all.
From a pure semantic perspective, this is fine -- kernel threads won't
attempt to access user pages, so having stale TLB entries doesn't matter.
Unfortunately, I forgot about a subtlety. By skipping TLB flushes,
we also allow any paging-structure caches that may exist on the CPU
to become incoherent. This means that we can have a
paging-structure cache entry that references a freed page table, and
the CPU is within its rights to do a speculative page walk starting
at the freed page table.
I can imagine this causing two different problems:
- A speculative page walk starting from a bogus page table could read
IO addresses. I haven't seen any reports of this causing problems.
- A speculative page walk that involves a bogus page table can install
garbage in the TLB. Such garbage would always be at a user VA, but
some AMD CPUs have logic that triggers a machine check when it notices
these bogus entries. I've seen a couple reports of this.
Boris further explains the failure mode:

To fix this, reinstate TLB coherence in lazy mode. With this patch
applied, we do it in one of two ways:
- If we have PCID, we simply switch back to init_mm's page tables
when we enter a kernel thread -- this seems to be quite cheap
except for the cost of serializing the CPU.
- If we don't have PCID, then we set a flag and switch to init_mm
the first time we would otherwise need to flush the TLB.
The /sys/kernel/debug/x86/tlb_use_lazy_mode debug switch can be changed
to override the default mode for benchmarking.
In theory, we could optimize this better by only flushing the TLB in
lazy CPUs when a page table is freed. Doing that would require
auditing the mm code to make sure that all page table freeing goes
through tlb_remove_page() as well as reworking some data structures
to implement the improved flush logic.
