[PATCH] downstream: KVM: arm64: Initialize HCRX_EL2 for FEAT_HAFT
by Qi Xi 16 Jul '25

16 Jul '25

From: Yicong Yang <yangyicong(a)hisilicon.com> FEAT_HAFT is enabled at boot by TCR2_EL1 which is controlled by HCRX_EL2. Back port the initialization part of HCRX_EL2 to support HAFT form [1][2]. Virtualization part (world switch) is not ported since it's said to have no such scenarios.

[PATCH OLK-6.6] drm: phytium: fix NULL dereference issue in drm_gem_object_free

From: Li Chen <chenl311(a)chinatelecom.cn> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICGG2A ---------------------------------------------------------------------- Syzkaller crashed kernel in drm path.

[PATCH 01/15] cpu/SMT: Provide a default topology_is_primary_thread()
by Qi Xi 16 Jul '25

16 Jul '25

From: Yicong Yang <yangyicong(a)hisilicon.com> commit 4b455f59945aab5610828a1320b045c82cbe8852 upstream. Currently if architectures want to support HOTPLUG_SMT they need to provide a topology_is_primary_thread() telling the framework which thread in the SMT cannot offline. However arm64 doesn't have a restriction on which thread in the SMT cannot offline, a simplest choice is that just make 1st thread as the "primary" thread. So just make this as the default implementation in the framework and let architectures like x86 that have special primary thread to override this function (which they've already done). There's no need to provide a stub function if !CONFIG_SMP or !CONFIG_HOTPLUG_SMT. In such case the testing CPU is already the 1st CPU in the SMT so it's always the primary thread.

[PATCH 01/12] cpufreq: Support per-policy performance boost
by Qi Xi 16 Jul '25

16 Jul '25

From: Jie Zhan <zhanjie9(a)hisilicon.com> commit 218a06a79d9a98a96ef46bb003d4d8adb0962056 upstream. The boost control currently applies to the whole system. However, users may prefer to boost a subset of cores in order to provide prioritized performance to workloads running on the boosted cores. Enable per-policy boost by adding a 'boost' sysfs interface under each policy path. This can be found at: /sys/devices/system/cpu/cpufreq/policy<*>/boost Same to the global boost switch, writing 1/0 to the per-policy 'boost' enables/disables boost on a cpufreq policy respectively. The user view of global and per-policy boost controls should be: 1. Enabling global boost initially enables boost on all policies, and per-policy boost can then be enabled or disabled individually, given that the platform does support so. 2. Disabling global boost makes the per-policy boost interface illegal.

[PATCH 01/15] cpu/SMT: Provide a default topology_is_primary_thread()
by Qi Xi 16 Jul '25

16 Jul '25

From: Yicong Yang <yangyicong(a)hisilicon.com> commit 4b455f59945aab5610828a1320b045c82cbe8852 upstream. Currently if architectures want to support HOTPLUG_SMT they need to provide a topology_is_primary_thread() telling the framework which thread in the SMT cannot offline. However arm64 doesn't have a restriction on which thread in the SMT cannot offline, a simplest choice is that just make 1st thread as the "primary" thread. So just make this as the default implementation in the framework and let architectures like x86 that have special primary thread to override this function (which they've already done). There's no need to provide a stub function if !CONFIG_SMP or !CONFIG_HOTPLUG_SMT. In such case the testing CPU is already the 1st CPU in the SMT so it's always the primary thread.
