2020-07-01drm/amdgpu/atomfirmware: fix vram_info fetching for renoirAlex Deucher1-0/+1
Renoir uses integrated_system_info table v12. The table has the same layout as v11 with respect to this data. Just reuse the existing code for v12 for stable.

2020-07-01coresight: etmv4: Fix CPU power management setup in probe() functionMike Leach1-29/+53
The current probe() function calls a pair of cpuhp_xxx API functions to setup CPU hotplug handling. The hotplug lock is held for the duration of the two calls and other CPU related code using cpus_read_lock() / cpus_read_unlock() calls. The problem is that on error states, goto: statements bypass the cpus_read_unlock() call. This code has increased in complexity as the driver has developed. This patch introduces a pair of helper functions etm4_pm_setup_cpuslocked() and etm4_pm_clear() which correct the issues above and group the PM code a little better. The two functions etm4_cpu_pm_register() and etm4_cpu_pm_unregister() are dropped as these call cpu_pm_register_notifier() / ..unregister_notifier() dependent on CONFIG_CPU_PM - but this define is used to nop these functions out in the pm headers - so the wrapper functions are superfluous.

2020-07-01coresight: cti: Fix error handling in probeDan Carpenter1-42/+54
There were a couple problems with error handling in the probe function: 1) If the "drvdata" allocation failed then it lead to a NULL dereference. 2) On several error paths we decremented "nr_cti_cpu" before it was incremented which lead to a reference counting bug. There were also some parts of the error handling which were not bugs but were messy. The error handling was confusing to read. It printed some unnecessary error messages. The simplest way to fix these problems was to create a cti_pm_setup() function that did all the power management setup in one go. That way when we call cti_pm_release() we don't have to deal with the complications of a partially configured power management config. I reversed the "if (drvdata->ctidev.cpu >= 0)" condition in cti_pm_release() so that it mirros the new cti_pm_setup() function.

[Why] Changes that are fast don't require updating DLG parameters making this call unnecessary. Considering this is an expensive call it should not be done on every flip. DML touches clocks, p-state support, DLG params and a few other DC internal flags and these aren't expected during fast. A hang has been reported with this change when called on every flip which suggests that modifying these fields is not recommended behavior on fast updates.

Alexandre Oliva has recently removed these files from Linux Libre with concerns that the sources weren't available. The sources are available on IGT repository, and only open source tools are used to generate the {ivb,hsw}_clear_kernel.c files. However, the remaining concern from Alexandre Oliva was around GPL license and the source not been present when distributing the code. So, it looks like 2 alternatives are possible, the use of linux-firmware.git repository to store the blob or making sure that the source is also present in our tree. Since the goal is to limit the i915 firmware to only the micro-controller blobs let's make sure that we do include the asm sources here in our tree. Btw, I tried to have some diligence here and make sure that the asms that these commits are adding are truly the source for the mentioned files: igt$ ./scripts/generate_clear_kernel.sh -g ivb \ -m ~/mesa/build/src/intel/tools/i965_asm Output file not specified - using default file "ivb-cb_assembled" Generating gen7 CB Kernel assembled file "ivb_clear_kernel.c" for i915 driver... igt$ diff ~/i915/drm-tip/drivers/gpu/drm/i915/gt/ivb_clear_kernel.c \ ivb_clear_kernel.c < * Generated by: IGT Gpu Tools on Fri 21 Feb 2020 05:29:32 AM UTC > * Generated by: IGT Gpu Tools on Mon 08 Jun 2020 10:00:54 AM PDT 61c61 < }; > }; \ No newline at end of file igt$ ./scripts/generate_clear_kernel.sh -g hsw \ -m ~/mesa/build/src/intel/tools/i965_asm Output file not specified - using default file "hsw-cb_assembled" Generating gen7.5 CB Kernel assembled file "hsw_clear_kernel.c" for i915 driver... igt$ diff ~/i915/drm-tip/drivers/gpu/drm/i915/gt/hsw_clear_kernel.c \ hsw_clear_kernel.c 5c5 < * Generated by: IGT Gpu Tools on Fri 21 Feb 2020 05:30:13 AM UTC > * Generated by: IGT Gpu Tools on Mon 08 Jun 2020 10:01:42 AM PDT 61c61 < }; > }; \ No newline at end of file Used IGT and Mesa master repositories from Fri Jun 5 2020) IGT: 53e8c878a6fb ("tests/kms_chamelium: Force reprobe after replugging the connector") Mesa: 5d13c7477eb1 ("radv: set keep_statistic_info with RADV_DEBUG=shaderstats") Mesa built with: meson build -D platforms=drm,x11 -D dri-drivers=i965 \ -D gallium-drivers=iris -D prefix=/usr \ -D libdir=/usr/lib64/ -Dtools=intel \ -Dkulkan-drivers=intel && ninja -C build v2: Header clean-up and include build instructions in a readme (Chris) Modified commit message to respect check-patch Reference: http://www.fsfla.org/pipermail/linux-libre/2020-June/003374.html Reference: http://www.fsfla.org/pipermail/linux-libre/2020-June/003375.html Fixes: 47f8253d2b89 ("drm/i915/gen7: Clear all EU/L3 residual contexts") Cc: <[email protected]> # v5.7+ Cc: Alexandre Oliva <[email protected]> Cc: Prathap Kumar Valsan <[email protected]> Cc: Akeem G Abodunrin <[email protected]> Cc: Mika Kuoppala <[email protected]> Cc: Chris Wilson <[email protected]> Cc: Jani Nikula <[email protected]> Cc: Joonas Lahtinen <[email protected]> Signed-off-by: Rodrigo Vivi <[email protected]> Reviewed-by: Jon Bloomfield <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit 5a7eeb8ba143d860050ecea924a8f074f02d8023) Signed-off-by: Jani Nikula <[email protected]>

2020-06-28net: get rid of lockdep_set_class_and_subclass()Cong Wang2-6/+4
lockdep_set_class_and_subclass() is meant to reduce the _nested() annotations by assigning a default subclass. For addr_list_lock, we have to compute the subclass at run-time as the netdevice topology changes after creation. So, we should just get rid of these lockdep_set_class_and_subclass() and stick with our _nested() annotations.
