[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.

[PATCH] irqchip/gic-v3-its: Fix the ITT address changing for hebernation.
by Hongbo Yao 20 Apr '20

20 Apr '20

From: Sunnanyong <sunnanyong(a)huawei.com> If we want to support S4 (suspend to Disk), it is necessary to guarantee that the ITS tables are at the same address in the booting kernel and the resumed kernel. That covers all the ITS tables and as well as the RDs'. To support this, allocting the itt memory from memory pool intead.

[PATCH 00/22] Add support for Hygon Dhyana Family 18h processor
by Pu Wen 20 Apr '20

20 Apr '20

As a new x86 CPU Vendor, Chengdu Haiguang IC Design Co., Ltd (Hygon) is a Joint Venture between AMD and Haiguang Information Technology Co., Ltd., and aims at providing high performance x86 processor for China server market. The first generation Hygon's processor(Dhyana) originates from AMD technology and shares most of the architecture with AMD's family 17h, but with different CPU Vendor ID("HygonGenuine")/PCIE Device Vendor ID (0x1D94)/Family series number (Family 18h). To enable the support of Linux kernel to Hygon's CPU, we added a new vendor type (X86_VENDOR_HYGON, with value of 9) in arch/x86/include/ asm/processor.h, and shared most of kernel support codes with AMD family 17h. As Hygon will negotiate with AMD to make sure that only Hygon will use family 18h, so try to minimize code modification and share most codes with AMD under this consideration. This patch series have been applied and tested successfully on Hygon Dhyana SoC silicon. Also tested on AMD EPYC (Family 17h) processor, it works fine and makes no harm to the existing codes. This patch series are created for the current branch openEuler-1.0-LTS.
