[alsa-devel] [PATCH 0/6] ASoC: SOF: refactor duplicated code between Intel and i.MX8
During the initial i.MX patch reviews on GitHub, we realized a lot of the i.MX mailbox/window code was common with the Intel loader code except for a couple of offsets. Most of the credit goes to Daniel Baluta for working on this series which adds a better abstraction and reduces code duplication. Comments from Keyon and Ranjani helped remove unnecessary parts kept for historical reasons and improve the code overall.
Daniel Baluta (6): ASoC: SOF: Remove call to snd_sof_dsp_mailbox_init ASoC: SOF: Introduce snd_sof_dsp_get_mailbox_offset ASoC: SOF: Introduce snd_sof_dsp_get_window_offset ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creation ASoC: SOF: Intel: bdw: Use generic function for fw ready / mem windows creation ASoC: SOF: Intel: hda: Use generic function for fw ready / mem windows creation

From: Daniel Baluta daniel.baluta@nxp.com
This is reserved for some historical reason, we didn't enable memory windows for byt/bdw at the beginning, to make it compatible, we get those mailbox offsets from fw_ready struct firstly, and then update them if they existed in the following memory windows, to make sure the mailbox still can be used if no memory windows are created.
With this change all platforms have the same implementation for xxx_fw_ready function so that we can refactor it in a common file.

This will allow us to export mailbox offset in order to read the fw_ready message from.

From: Daniel Baluta daniel.baluta@nxp.com
There is a lot of duplicate code when processing IPC firmware ready notification and creating memory windows.
First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready
So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value.
Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value.
You've already explained your goal. These details are unnecessary.
Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

Hmm, even the commit message mentions two steps, not one. Splitting this commit into two - introduction of new generic functions and byt alignment towards the newly added approach - seems reasonable. Bdw & hda followups already make good examples.

They don't hurt and help explain the approach.

The last two just remove the duplicate code and align on using the common helpers. In the initial step we still need to move the code from baytrail to the common function. Doing it in two steps doesn't bring much added value IMO. To preserve git bisect support, you'd need to add a new common code, then remove the baytrail one in a follow-up patch. It'd make it less self-explanatory where this new code comes from.
The patch
ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creation
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.

From: Daniel Baluta daniel.baluta@nxp.com Date: Wed, 7 Aug 2019 10:02:01 -0500 Subject: [PATCH] ASoC: SOF: Intel: byt: Refactor fw ready / mem windows creation
There is a lot of duplicate code when processing IPC firmware ready notification and creating memory windows.
First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready
So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value.
Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

bdw_get_windows / bdw_fw_ready is identical with the generic implementation introduced in a previous patch.
So remove bdw_get_windows / bdw_fw_ready and use the generic sof_get_windows version.
Do not forget to implement get_mailbox_offset/get_window_offset so that we export the correct mailbox/memory window offset to the outside world.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

From: Daniel Baluta daniel.baluta@nxp.com Date: Wed, 7 Aug 2019 10:02:02 -0500 Subject: [PATCH] ASoC: SOF: Intel: bdw: Use generic function for fw ready / mem windows creation
bdw_get_windows / bdw_fw_ready is identical with the generic implementation introduced in a previous patch.
So remove bdw_get_windows / bdw_fw_ready and use the generic sof_get_windows version.
Do not forget to implement get_mailbox_offset/get_window_offset so that we export the correct mailbox/memory window offset to the outside world.

We can use generic sof_fw_ready function and reduce code duplication. Careful here that we need to provide the implementation for get_mailbox_offset and get_window_offset.
