Uacce (Unified/User-space-access-intended Accelerator Framework) targets to
provide Shared Virtual Addressing (SVA) between accelerators and processes.
So accelerator can access any data structure of the main cpu.
This differs from the data sharing between cpu and io device, which share
data

Uacce (Unified/User-space-access-intended Accelerator Framework) is
a kernel module targets to provide Shared Virtual Addressing (SVA)
between the accelerator and process.
This patch add document to explain how it works.

Apologies, I've been traveling for the last few days and haven't
managed to try it yet.
I'll do it later today though and let you know.

As we've seen from USB and other areas[1], we need to always do runtime
checks for DMA operating on memory regions that might be remapped. This
adds vmap checks (similar to those already in USB but missing in other
places) into dma_map_single() so all callers benefit from the checking.
[1]
v4: use dev_WARN_ONCE() and improve report string (gregkh, robin)
v3: https://lore.kernel.org/lkml/20191010222829.21940-1-keesc...@chromium.org
v2: https://lore.kernel.org/lkml/201910041420.F6E55D29A@keescook
v1: https://lore.kernel.org/lkml/201910021341.7819A660@keescook
Duplicating patch 1
Now that the vmap area checks are being performed in the DMA
infrastructure directly, there is no need to repeat them in USB.
