1. Add mechanism(s) to trigger syncpoint fence scan when syncpoint increment UMD called. Following methods are added. - METHOD-1: Check fence expire in user context when syncpoint increment UMD API is called. - METHOD-2: Add tasklet based mechanism that schedule tasklet to scan for syncpoint fence expiry. This also improve signaling latency. METHOD-1 is enabled by default, to enable METHOD-2 define MACRO "HOST1X_EMU_SYNC_INC_TASKLET". 2. Add interface "host1x_syncpt_fence_scan()" that can be called from client interrupt handler to initiate syncpoint fence scan.

* TODO: Remove header after pre-silicon verification
|
|
* This header is required till emulation driver verification is done on Tho-r
|
|
* VDK platform. Since we are exporting new kernel symbol, header with declarion
|
|
* of modified symbols is required
|
|
*
|
|
* Changed cannot be added in orignal Host1x driver header files ("linux/nvhost.h"
|
|
* and "host1x-next.h") due to Host1x driver and other dependent drivers. Note in
|
|
* Tho-r verification config both the driver will co-exist.
|
|
*
|
|
* Some data structure are also re-delacred in this header for case where client
|
|
* driver wants to verify over emulation driver.
