Anyhow, this print is coming from util/evsel.c: perf_evsel__open_strerror()

Allocation of a frame buffer memory in a special memory region
allows bypassing of so-called IO Coherency aperture
which is typically set as a range 0x8z-0xAz.
I.e. all data traffic to PGU bypasses IO Coherency block
and saves its bandwidth for other peripherals.
Even though for AXS101 (which sor
Now when ARC supports reserved memory areas and
per-device coherent DMA allocations we may switch ARC PGU
to use of those dedicated areas.
One of the benefits we may move frame-buffer area out
from IO Coherency aperture and so significantly
reduce IOC utilization allowing less demanding
peripheral
This mini-series allows to allocate frame buffer memory in desired

ARC AXS10x platforms consist of a mainboard with several peripherals.
One of those peripherals is an HDMI output port controlled by the ADV7511
transmitter.
This patch set adds I2S audio for the AXS10x platform.
Changes v5 -> v6
* Use SNDRV_DMA_TYPE_CONTINUOUS
Changes v4 -> v5
* Resolve undefine
This patch updates documentation for the Designware I2S
driver.

HDMI audio support was added to the AXS board using an
I2S cpu driver and a custom platform driver.
The platform driver supports two channels @ 16 bits with
rates 32k, 44.1k and 48k.
Although the mainline I2S driver uses ALSA DMA engine,
this controller can be built without DMA support so it
