* ASoC: Intel: Skylake: Await purge request ack on CNLCezary Rojewski2020-03-101-0/+1
| | | | | | | | | | | | | | Each purge request is sent by driver after master core is powered up and unresetted but before it is unstalled. On unstall, ROM begins processing the request and initializing environment for FW load. Host should await ROM's ack before moving forward. Without doing so, ROM init poll may start too early and false timeouts can occur.

* ASoC: Intel: Allow for ROM init retry on CNL platformsCezary Rojewski2020-03-101-0/+1
| | | | | | | | | | | | | Due to unconditional initial timeouts, firmware may fail to load during its initialization. This issue cannot be resolved on driver side as it is caused by external sources such as CSME but has to be accounted for nonetheless.

* ASoC: Intel: Skylake: Do not disable FW notificationsAmadeusz Sławiński2019-07-241-1/+0
| | | | | | | | | | | | | | | As per FW team recommendation we should not disable notifications. By default, all notifications are enabled in DSP firmware. These notifications provide a vital information whenever an error occurs. Currently, driver disables them during boot sequences. By doing so, Skylake may silently ignore severe stream errors. Correct that by removing permissive code.

* ASoC: Intel: Skylake: Merge skl_sst and skl into skl_dev structCezary Rojewski2019-07-241-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Skylake driver is divided into two modules: - snd_soc_skl - snd_soc_skl_ipc and nothing would be wrong if not for the fact that both cannot exist without one another. IPC module is not some kind of extension, as it is the case for snd_hda_ext_core which is separated from snd_hda_core - legacy hda interface. It's as much core Skylake module as snd_soc_skl is. Statement backed up by existence of circular dependency between this two. To eliminate said problem, struct skl_sst has been created. From that very momment, Skylake has been plagued by header errors (incomplete structs, unknown references etc.) whenever something new is to be added or code is cleaned up. As this design is being corrected, struct skl_sst is no longer needed, so combine it with struct skl. To avoid ambiguity when searching for skl stuff (struct skl *skl) it has also been renamed to skl_dev. No functional changes.

| | | | | | | | | | | | | | | | | | | | | | When module size > DMA buffer size, driver copies first chunk and waits for the BDL complete interrupt. BDL complete interrupt never occurs and wait time expires as module load IPC is not send to start the DMA from DSP. To fix the above issue need to follow the below steps: 1. After copying the first chunk, send the module load IPC to start the DMA. 2. Wait for the BDL interrupt. Once interrupt is received, copy the next chunk. 3. Continue step 2 till all bytes are copied. 4. When all the bytes are copied (bytes_left = 0), wait for module load IPC response 5. Handled module load IPC response messages, check the load module IPC response and wake up the thread to complete module load.

| | | | | | | | | | | | | | | | | | | | Driver needs to send unique module instance id to firmware while creating the module and uses this id to communicate with DSP for setting parameters while audio use case is ongoing. But, we have upper bound of instance ID. The current IDs are coming from topology but it doesn't know the upper bound and can't assign unique id's subject to upper bounds as we can create a big graph but not all parts running at same time. This patch adds a 128bit unique id management routines which are built on top of ffz() for faster implementation. Unfortunately ffz() works on 32bits values, so additional code is added on top of ffz() to create a 128bit unique id.
