[PATCH] ACPI: GED: implement powerkey evged freeze function
by Hongbo Yao 24 Apr '20

24 Apr '20

From: Huang jun <huangjun61(a)huawei.com> If we want acpi ged to support wake from freeze, we need to implement the suspend/resume function. In these two methods, ACPI's _GPO, GPP method is called to realize the setting of sleep flag and anti-shake.

[PATCH v1] scsi: hisi_sas: do not reset the timer to wait for phyup when phy already up
by Luo Jiaxing 22 Apr '20

22 Apr '20

We found out that after phy up, the hardware report another oob interrupt, but did not follow a phy up interrupt. like: oob ready -> phy up -> DEV found -> oob read -> wait phy up -> timeout We run link reset when wait phy up timeout, and it make a normal disk into reset processing. So we made some circumvention action in the code, so that this abnormal oob interrupt will not start the timer to wait for phy up.
