Let's say 2G radio crashed, Q6 should pass this info to APSS. Only Q6 processor interrupts registered with APSS. Obviously Q6 should crash and raise fatal interrupt to APSS. Due to this 5G radio also crashed. But no issue in 5G radio, because of 2G radio crash 5G radio also impacted.Please wrap commit message according to Linux coding style / submission process (neither too early nor over the limit): https://elixir.bootlin.com/linux/v5.18-rc4/source/Documentation/process/submitting-patches.rst#L586
Sure, i will update.
In multi pd model, this problem is resolved. Here WCSS functionality (WiFi radio's) moved out from Q6 root pd to a separate user pd. Due to this, radio's independently pass their status info to APPS with out crashing Q6. So other radio's won't be impacted. --------- |WiFi | --> |2G radio| | --------- ------ Start Q6 ------- | | | ------------------> | | | | | Start WCSS PD1 (2G) | | | |APSS| ----------------------->|QDSP6|-----| | | Start WCSS PD1 (5G) | | | | ----------------------->| |-----| ------ ------- | | | ----------- |-->|WiFi | |5G radio | ----------- According to linux terminology, here consider Q6 as root i.e it provide all services, WCSS (wifi radio's) as user i.e it uses services provided by root. Since Q6 root & WCSS user pd's able to communicate with APSS individually, multipd remoteproc driver registers each PD with rproc framework. Here clients (Wifi host drivers) intrested on WCSS PD rproc, so multipd driver start's root pd in the context of WCSS user pd rproc start. Similarly on down path, root pd will be stopped after wcss user pd stopped. Here WCSS(user) PD is dependent on Q6(root) PD, so first q6 pd should be up before wcss pd. After wcss pd goes down, q6 pd should be turned off. rproc->ops->start(userpd_rproc) { /* Boot root pd rproc */ rproc_boot(upd_dev->parent); --- /* user pd rproc start sequence */ --- --- } With this way we ensure that root pd brought up before userpd. rproc->ops->stop(userpd_rproc) { --- --- /* user pd rproc stop sequence */ --- --- /* Shutdown root pd rproc */ rproc_shutdown(upd_dev->parent); } After userpd rproc stops, root pd rproc will be stopped. IPQ5018, IPQ9574 supports multipd remoteproc driver.
