2023-05-30LWIS: Update read buffer pointerMeghana Barkalle
While executing the remaining transaction based on the transaction process limit, there is a need to save the location where the read buffer should be updated in the response. Queue the work on the tranaction/I2C worker thread again if there are any pending entries to be processed further.

2023-05-10LWIS: Fix transaction freeMeghana Barkalle
Transaction is not set to NULL appropriately after being freed. This can lead to usage of transaction even after free in some cases. This fix will allow setting the freed transaction memory to NULL appropriately. Bug: 281124077 Test: GCA Smoke Test Change-Id: Idf36215eb1fc7cec0f940f0efe7b30dc4ee13fbc
2023-05-08Add entry processing limit for queued transactionsMeghana Barkalle
When the numbers of processing entries need to be controlled then user could specify the following tag in the I2C device dt entry: transaction-process-limit When this entry is not specified, the default system behaviour is to process all the entries Test: GCA Smoke Test Bug: 274038588 Change-Id: I7c5979c84560e5b505a481b15889a782bb154062

2022-06-01LWIS: add LWIS_FENCE_ENABLED for zumaWill McVicker
The LWIS fence feature was only added for devices launching with the 5.15 kernel. Since this feature modifies the UAPI by introducing the variable trigger_condition, we need to compile it out of the P21 driver. We can do that by moving all the fence related code to lwis_fence.c and using the LWIS_FENCE_ENABLED define to disable it for P21. Refer to ag/18085883 for more platform details. Tested: verify camera on P21 Bug: 229024993 Signed-off-by: Will McVicker <willmcvicker@google.com> Change-Id: I2145b6198c137557022649d40881f91cdc1418b1

Mutex un/lock could be expensive, especially if this is done on a per-entry basis. Changed to lock for the entirety of one transaction.

2020-07-24Transaction: Fix race condition in submission.Edmond Chung
It's possible that event would trigger while transaction is in the process of submission. That leads to transaction being added to the pending list but with no chance of being triggered.
