| | | | | | | | | | | | | | | | | | | | | | | | In multi-threads stress tests, some synchronization issues were found. Here are the fixes for them. Change-Id: I43a1fef5771af08f3fe7c0be486cc2d36667e773 Signed-off-by: Yong Ding <yongding@codeaurora.org>
| * | soc: qcom: hab: use separated irq for each pchanYong Ding2017-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this change, all physical channels share only one single irq issued by only one single virtual shmem device from hypervisor. To achieve better performance, each physical channel will be built on top of one virtual shmem device with its own irq.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the new feature to support multiple Guest Virtual Machiness communications. In the past, HAB driver supported the communication between only one single GVM and the host machine. With this new feature, more than one GVMs can communicate with the host machine over HAB driver.

* | | | icnss: Do not send uevent when driver is unloadingYuanyuan Liu2017-12-20
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If modem crashed during wlan driver unloading, icnss driver will call driver uevent callback to send FW down uevent when it receives BEFORE_SHUTDOWN notification. If wlan driver is de-initialized just before the callback is called, kernel will panic as driver's context is freed. This can be avoid by not sending uevent when wlan host driver is unloading. Instead, icnss driver will provide an API to host driver to check if WLAN FW is down or not.

When wlan module starts, it will hold a rtnl_lock and wait for FW response. If SSR happened at this point, it will send ssr notification to all the registed modules one by one. It will send notification to IPA first, which will also tried to get a hold of rtnl_lock. Since ssr notification is synchronized, IPA won't be able to return because of failing to acquire the lock and wlan driver won't release the rtnl_lock until it timeout and crash. Only graceful to avoid this deadlock is to get early modem crash notification from platform via a path which does not acquire RTNL lock and this way once driver has received early crash notification it can reject interface up. Modem notification comes to icnss before IPA, hence send early crash notification in modem SSR handler so that wlan driver can release RTNL lock as soon as possible.
