* | ASoC: Intel: Fix race condition in IPC rx listGustaw Lewandowski2019-06-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since there are multiple IPCs being sent in a short span of time, there is a possibility of more than one message being on the Rx list after receiving response from firmware. In such cases, when the first notification of interrupt from firmware is received, driver retrieves the message from the Rx list but does not delete it from the list till the next lock. In the meantime, when another interrupt is received from the firmware, driver is reading the previous message again since the previous message has not been removed from the list.

* | ASoC: Intel: Skylake: Read HIPCT extension before clearing DONE bitCezary Rojewski2019-06-251-1/+1
|/ | | | | | | | | | | | | | Host clears DONE bit to signal IPC target it has completed the operation. Once this is done, IPC target i.e. DSP may proceed with the next reply, filling registers with new portion of data. Because of this, host should always read all registers prior to clearing DONE and BUSY bits to ensure no desynchronization happens the time in between clearing bits and reading message data (here, extension).

* ASoC: Intel: Skylake: Fix IPC rx_list corruptionPardha Saradhi K2017-05-241-0/+5
| | | | | | | | | | | | | | | | | | In SKL+ platforms, all IPC commands are serialised, i.e. the driver sends a new IPC to DSP, only after receiving a reply from the firmware for the current IPC. Hence it seems apparent that there is only a single modifier of the IPC RX List. However, during an IPC timeout case in a multithreaded environment, there is a possibility of the list element being deleted two times if not properly protected. So, use spin lock save/restore to prevent rx_list corruption. Signed-off-by: Pardha Saradhi K <pardha.saradhi.kesapragada@intel.com> Signed-off-by: Subhransu S.

* ASoC: Intel: Skylake: Fix module load when module size > DMA buffer sizeJeeja KP2017-03-151-21/+45
| | | | | | | | | | | | | | | | | | | | | | 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.

* kthread: kthread worker API cleanupPetr Mladek2016-10-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A good practice is to prefix the names of functions by the name of the subsystem. The kthread worker API is a mix of classic kthreads and workqueues. Each worker has a dedicated kthread. It runs a generic function that process queued works. It is implemented as part of the kthread subsystem. This patch renames the existing kthread worker API to use the corresponding name from the workqueues API prefixed by kthread_: __init_kthread_worker() -> __kthread_init_worker() init_kthread_worker() -> kthread_init_worker() init_kthread_work() -> kthread_init_work() insert_kthread_work() -> kthread_insert_work() queue_kthread_work() -> kthread_queue_work() flush_kthread_work() -> kthread_flush_work() flush_kthread_worker() -> kthread_flush_worker() Note that the names of DEFINE_KTHREAD_WORK*() macros stay as they are. It is common that the "DEFINE_" prefix has precedence over the subsystem names. Note that INIT() macros and init() functions use different naming scheme. There is no good solution. There are several reasons for this solution: + "init" in the function names stands for the verb "initialize" aka "initialize worker". While "INIT" in the macro names stands for the noun "INITIALIZER" aka "worker initializer". + INIT() macros are used only in DEFINE() macros + init() functions are used close to the other kthread() functions. It looks much better if all the functions use the same scheme. + There will be also kthread_destroy_worker() that will be used close to kthread_cancel_work(). It is related to the init() function. Again it looks better if all functions use the same naming scheme. + there are several precedents for such init() function names, e.g. amd_iommu_init_device(), free_area_init_node(), jump_label_init_type(), regmap_init_mmio_clk(), + It is not an argument but it was inconsistent even before.

* ASoC: Intel: Skylake: fix typo in sizeofVincent Stehlé2015-11-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The size of the pointer to a data structure to send is erroneously passed to sst_ipc_tx_message_wait() as its tx_bytes argument. It should be given the size of the pointed skl_ipc_dxstate_info structure instead. Coincidentally, both the pointer and the structure have the same size of 8 bytes on a 64 bit machine, which "masks" the issue. Compiling for 32 bit reveals the issue more clearly. Fix the typo for correctness, and to make the code robust to future evolutions of the skl_ipc_dxstate_info structure size.
