2023-12-04drm/i915/display: Handle invalid fb_modifier in intel_fb_modifier_to_tilingJouni Högander
Lookup_modifier is returning INTEL_PLANE_CAP_TILING_4 on invalid fb_modifier value. Use lookup_modifier_or_null in intel_fb_modifier_to_tiling and return I915_TILING_NONE in case lookup_modifier_or_null returns null.

2023-12-04drm/i915/display: use intel_bo_to_drm_bo in intel_fb.cJouni Högander
We are preparing for Xe driver. I915 and Xe object implementation are differing. Do not use i915_gem_object->base directly. Instead use intel_bo_to_drm_bo. Also use drm_gem_object_put instead of i915_gem_object_put. This should be ok as i915_gem_object_put is really just doing __drm_gem_object_put.

2023-12-03io_uring: fix mutex_unlock with unreferenced ctxPavel Begunkov
Callers of mutex_unlock() have to make sure that the mutex stays alive for the whole duration of the function call. For io_uring that means that the following pattern is not valid unless we ensure that the context outlives the mutex_unlock() call. mutex_lock(&ctx->uring_lock); req_put(req); // typically via io_req_task_submit() mutex_unlock(&ctx->uring_lock); Most contexts are fine: io-wq pins requests, syscalls hold the file, task works are taking ctx references and so on. However, the task work fallback path doesn't follow the rule.

2023-12-03drm: remove drm_bridge_hpd_disable() from drm_bridge_connector_destroy()Abhinav Kumar
drm_bridge_hpd_enable()/drm_bridge_hpd_disable() callbacks call into the respective driver's hpd_enable()/hpd_disable() ops. These ops control the HPD enable/disable logic which in some cases like MSM can be a dedicate hardware block to control the HPD. During probe_defer cases, a connector can be initialized and then later destroyed till the probe is retried. During connector destroy in these cases, the hpd_disable() callback gets called without a corresponding hpd_enable() leading to an unbalanced state potentially causing even a crash. This can be avoided by the respective drivers maintaining their own state logic to ensure that a hpd_disable() without a corresponding hpd_enable() just returns without doing anything. However, to have a generic fix it would be better to avoid the hpd_disable() callback from the connector destroy path and let the hpd_enable() / hpd_disable() balance be maintained by the corresponding drm_bridge_connector_enable_hpd() / drm_bridge_connector_disable_hpd() APIs which should get called by drm_kms_helper_disable_hpd(). changes in v2: - minor change in commit text (Dmitry) Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230919174813.26958-1-quic_abhinavk@quicinc.com
2023-12-03drm: improve the documentation of connector hpd opsAbhinav Kumar
While making the changes in [1], it was noted that the documentation of the enable_hpd() and disable_hpd() does not make it clear that these ops should not try to do hpd state maintenance and should only enable/disable hpd related hardware for the connector. The state management of these calls to make sure these calls are balanced is handled by the DRM core and we should keep it that way to minimize the overhead in the drivers which implement these ops.

2023-12-03drm/msm/dp: incorporate pm_runtime framework into DP driverKuogee Hsieh
Currently DP driver is executed independent of PM runtime framework. This leads msm eDP panel can not being detected by edp_panel driver during generic_edp_panel_probe() due to AUX DPCD read failed at edp panel driver. Incorporate PM runtime framework into DP driver so that host controller's power and clocks are enable/disable through PM runtime mechanism. Once PM runtime framework is incorporated into DP driver, waking up device from power up path is not necessary. Hence remove it. After incorporating pm_runtime framework into eDP/DP driver, dp_pm_suspend() to handle power off both DP phy and controller during suspend and dp_pm_resume() to handle power on both DP phy and controller during resume are not necessary. Therefore both dp_pm_suspend() and dp_pm_resume() are dropped and replace with dp_pm_runtime_suspend() and dp_pm_runtime_resume() respectively.

The objpool uses a copy of object slot index internal loop, but the slot index can be changed on another processor in parallel. In that case, the difference of 'head' local copy and the 'slot->last' index will be bigger than local slot size. In that case, we need to re-read the slot::head to update it. - kretprobe: Fix to use appropriate rcu API for kretprobe holder. Since kretprobe_holder::rp is RCU managed, it should use rcu_assign_pointer() and rcu_dereference_check() correctly. Also adding __rcu tag for finding wrong usage by sparse. - rethook: Fix to use appropriate rcu API for rethook::handler.

2023-12-02r8169: fix rtl8125b PAUSE frames blasting when suspendedChunHao Lin
When FIFO reaches near full state, device will issue pause frame. If pause slot is enabled(set to 1), in this time, device will issue pause frame only once. But if pause slot is disabled(set to 0), device will keep sending pause frames until FIFO reaches near empty state. When pause slot is disabled, if there is no one to handle receive packets, device FIFO will reach near full state and keep sending pause frames. That will impact entire local area network. This issue can be reproduced in Chromebox (not Chromebook) in developer mode running a test image (and v5.10 kernel): 1) ping -f $CHROMEBOX (from workstation on same local network) 2) run "powerd_dbus_suspend" from command line on the $CHROMEBOX 3) ping $ROUTER (wait until ping fails from workstation) Takes about ~20-30 seconds after step 2 for the local network to stop working. Fix this issue by enabling pause slot to only send pause frame once when FIFO reaches near full state.

2023-12-02arm64: dts: rockchip: Fix Turing RK1 interrupt pinctrlsSam Edwards
The pinctrls for the hym8563 interrupt line and fan-tach input were both mistakenly defined as `pcfg_pull_none`. As these are active-low signals (level-triggered, in the hym8563 case) which may not be driven at times, these should really be pull-up. The lack of any bias results in spurious interrupts. Fix this by modifying the `rockchip,pins` properties as necessary to enable the pull-up resistors.

2023-12-02x86/CPU/AMD: Check vendor in the AMD microcode callbackBorislav Petkov (AMD)
Commit in Fixes added an AMD-specific microcode callback. However, it didn't check the CPU vendor the kernel runs on explicitly. The only reason the Zenbleed check in it didn't run on other x86 vendors hardware was pure coincidental luck: if (!cpu_has_amd_erratum(c, amd_zenbleed)) return; gives true on other vendors because they don't have those families and models. However, with the removal of the cpu_has_amd_erratum() in 05f5f73936fa ("x86/CPU/AMD: Drop now unused CPU erratum checking function") that coincidental condition is gone, leading to the zenbleed check getting executed on other vendors too. Add the explicit vendor check for the whole callback as it should've been done in the first place.
