ASoC: SOF: ipc: introduce cont_update_posn in sof_ipc_stream_params struct

2022-05-10T13:01:54+00:00

The host stream position is updated when no_stream_position is set as 0.
However current implementation updates host stream position only when
report data is larger than or equal to host period size which is decided
by the period size of host side. It maybe cause host stream position
update not in time. Therefore this patch introduces another field
"cont_update_posn", a boolean value aimed to update host stream position
continuously and based on period size of pipeline. It can get better
precise when need to update host stream position from firmware.

ASoC: SOF: make struct snd_sof_dai IPC agnostic

2022-03-09T13:30:09+00:00

Remove the comp_dai and dai_config members of struct snd_sof_dai and
replace it with a void *private field. Introduce a new struct
sof_dai_private_data that will contain the pointer to these two fields.
The topology parser will populate this structure and save it as part of
the "private" member in snd_sof_dai. Change all users of these fields to
use the private member instead.

Parse the UUID token and save it in the new uuid field in struct

ASoC: SOF: fix 32 signed bit overflow

2022-03-07T13:12:52+00:00

Shifting in a signed 32bit container past the signed bit is technically
undefined behaviour. Fix by using unsigned types. Found via cppcheck.

ASoC: SOF: Replace zero-length array with flexible-array member

2022-02-17T17:13:36+00:00

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use "flexible array members"[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

treewide: Replace zero-length arrays with flexible-array members

2022-02-17T13:00:39+00:00

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)

@@
identifier S, member, array;
type T1, T2;
@@

struct S {
  ...
  T1 member;
  T2 array[
- 0
  ];
};

UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

ASoC: SOF: add _D3_PERSISTENT flag to fw_ready message

2022-01-24T13:31:14+00:00

Add a bit definition to the fw_ready message, to denote if the FW
supports the IMR (Isolated Memory Region) restoring feature.

If the bit is set, the driver can skip downloading the firmware again
during system resume or runtime resume.

Bump the ABI version to 3.19 to make it aligned with FW side.
