perf spe-c2c record失败的问题
by haoxin 15 Dec '21

15 Dec '21

您好，我采用最细的openEuler-1.0测试perf spe-c2c的功能，但是发现/sys/devices下没有arm_spe_0这个目录执行perf spe-c2c record时显示： event syntax error: 'arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/' \___ Cannot find PMU `arm_spe_0'. Missing kernel support? 想问下您这是为什么？需要哪里开启spe功能吗？

[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 1/2] ACPI: GED: implement powerkey evged freeze function
by Hongbo Yao 21 Apr '20

21 Apr '20

From: huangjun <huangjun63(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 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.

[PATCH 1/2] btrfs: extent_io: Handle errors better in extent_write_full_page()
by Yang Yingliang 18 Apr '20

18 Apr '20

From: Qu Wenruo <wqu(a)suse.com> mainline inclusion from mainline-v5.2-rc2 commit 3065976b045f77a910809fa7699f99a1e7c0dbbb category: bugfix bugzilla: 13690 CVE: CVE-2019-19377 Introduce end_write_bio() for CVE-2019-19377. ------------------------------------------------- Since now flush_write_bio() could return error, kill the BUG_ON() first. Then don't call flush_write_bio() unconditionally, instead we check the return value from __extent_writepage() first. If __extent_writepage() fails, we do cleanup, and return error without submitting the possible corrupted or half-baked bio. If __extent_writepage() successes, then we call flush_write_bio() and return the result.
