2024-08-23pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPENícolas F. R. A. Prado
Despite its name, commit fed74d75277d ("pinctrl: mediatek: common-v2: Fix bias-disable for PULL_PU_PD_RSEL_TYPE") actually broke bias-disable for PULL_PU_PD_RSEL_TYPE. mtk_pinconf_bias_set_combo() tries every bias method supported by the pin until one succeeds. For PULL_PU_PD_RSEL_TYPE pins, before the breaking commit, mtk_pinconf_bias_set_rsel() would be called first to try and set the RSEL value (as well as PU and PD), and if that failed, the only other valid option was that bias-disable was specified, which would then be handled by calling mtk_pinconf_bias_set_pu_pd() and disabling both PU and PD. The breaking commit misunderstood this logic and added an early "return 0" in mtk_pinconf_bias_set_rsel(). The result was that in the bias-disable case, the bias was left unchanged, since by returning success, mtk_pinconf_bias_set_combo() no longer tried calling mtk_pinconf_bias_set_pu_pd() to disable the bias. Since the logic for configuring bias-disable on PULL_PU_PD_RSEL_TYPE pins required mtk_pinconf_bias_set_rsel() to fail first, in that case, an error was printed to the log, eg: mt8195-pinctrl 10005000.pinctrl: Not support rsel value 0 Ohm for pin = 29 (GPIO29) This is what the breaking commit actually got rid of, and likely part of the reason why that commit was thought to be fixing functionality, while in reality it was breaking it. Instead of simply reverting that commit, restore the functionality but in a way that avoids the error from being printed and makes the code less confusing: * Return 0 explicitly if a bias method was successful * Introduce an extra function mtk_pinconf_bias_set_pu_pd_rsel() that calls both mtk_pinconf_bias_set_rsel() (only if needed) and mtk_pinconf_bias_set_pu_pd() * And analogously for the corresponding getters Fixes: fed74d75277d ("pinctrl: mediatek: common-v2: Fix bias-disable for PULL_PU_PD_RSEL_TYPE") Signed-off-by: Nícolas F.

2024-08-23drm/amd/display: use a more lax vblank enable policy for older ASICsHamza Mahfooz
Ideally, we want to drop the legacy vblank enable for older ASICs. This should be possible now, since we can now specify how many frames we need to wait before disabling vblanking instead of being forced to either choose between no delay (which can still be buggy) and drm_vblank_offdelay (which is much longer by default than is required on AMD hardware).

2024-08-23drm/panic: Add a QR code panic screenJocelyn Falempe
This patch adds a new panic screen, with a QR code and the kmsg data embedded. If DRM_PANIC_SCREEN_QR_CODE_URL is set, then the kmsg data will be compressed with zlib and encoded as a numerical segment, and appended to the URL as a URL parameter. This allows to save space, and put about ~7500 bytes of kmsg data, in a V40 QR code. Linux distributions can customize the URL, and put a web frontend to directly open a bug report with the kmsg data. Otherwise the kmsg data will be encoded as a binary segment (ie raw ascii) and only a maximum of 2953 bytes of kmsg data will be available in the QR code. You can also limit the QR code size with DRM_PANIC_SCREEN_QR_VERSION.

2024-08-23drm/amdkfd: Change kfd/svm page fault drain handlingXiaogang Chen
When app unmap vm ranges(munmap) kfd/svm starts drain pending page fault and not handle any incoming pages fault of this process until a deferred work item got executed by default system wq. The time period of "not handle page fault" can be long and is unpredicable. That is advese to kfd performance on page faults recovery. This patch uses time stamp of incoming page fault to decide to drop or recover page fault. When app unmap vm ranges kfd records each gpu device's ih ring current time stamp. These time stamps are used at kfd page fault recovery routine. Any page fault happened on unmapped ranges after unmap events is application bug that accesses vm range after unmap. It is not driver work to cover that. By using time stamp of page fault do not need drain page faults at deferred work. So, the time period that kfd does not handle page faults is reduced and can be controlled.

2024-08-23irqchip/gic-v3: Init SRE before poking sysregsMark Rutland
The GICv3 driver pokes GICv3 system registers in gic_prio_init() before gic_cpu_sys_reg_init() ensures that GICv3 system registers have been enabled by writing to ICC_SRE_EL1.SRE. On arm64 this is benign as has_useable_gicv3_cpuif() runs earlier during cpufeature detection, and this enables the GICv3 system registers. On 32-bit arm when booting on an FVP using the boot-wrapper, the accesses in gic_prio_init() end up being UNDEFINED and crashes the kernel during boot. This is a regression introduced by the addition of gic_prio_init(). Fix this by factoring out the SRE initialization into a new function and calling it early in the three paths where SRE may not have been initialized: (1) gic_init_bases(), before the primary CPU pokes GICv3 sysregs in gic_prio_init(). (2) gic_starting_cpu(), before secondary CPUs initialize GICv3 sysregs in gic_cpu_init(). (3) gic_cpu_pm_notifier(), before CPUs re-initialize GICv3 sysregs in gic_cpu_sys_reg_init().

2024-08-23ASoC: Intel: soc-acpi-cht: Make Lenovo Yoga Tab 3 X90F DMI match less strictHans de Goede
There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it turns out that the 2G version has a DMI product name of "CHERRYVIEW D1 PLATFORM" where as the 4G version has "CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are unique enough that the product-name check is not necessary. Drop the product-name check so that the existing DMI match for the 4G RAM version also matches the 2G RAM version.

2024-08-23ASoC: Intel: Boards: Fix NULL pointer deref in BYT/CHT boards harderHans de Goede
Since commit 13f58267cda3 ("ASoC: soc.h: don't create dummy Component via COMP_DUMMY()") dummy codecs declared like this: SND_SOC_DAILINK_DEF(dummy, DAILINK_COMP_ARRAY(COMP_DUMMY())); expand to: static struct snd_soc_dai_link_component dummy[] = { }; Which means that dummy is a zero sized array and thus dais[i].codecs should not be dereferenced *at all* since it points to the address of the next variable stored in the data section as the "dummy" variable has an address but no size, so even dereferencing dais[0] is already an out of bounds array reference. Which means that the if (dais[i].codecs->name) check added in commit 7d99a70b6595 ("ASoC: Intel: Boards: Fix NULL pointer deref in BYT/CHT boards") relies on that the part of the next variable which the name member maps to just happens to be NULL. Which apparently so far it usually is, except when it isn't and then it results in crashes like this one: [ 28.795659] BUG: unable to handle page fault for address: 0000000000030011 ...

2024-08-23OPP: Fix support for required OPPs for multiple PM domainsUlf Hansson
It has turned out that having _set_required_opps() to recursively call dev_pm_opp_set_opp() to set the required OPPs, doesn't really work as well as we expected. More precisely, at each recursive call to dev_pm_opp_set_opp() we are changing an OPP for a required_dev that belongs to a required-OPP table. The problem with this, is that we may have several devices sharing the same required-OPP table, which leads to an incorrect behaviour in regards to aggregating the per device votes. To fix the problem for a required-OPP table belonging to a PM domain, which is the only existing usecase for now, let's simply replace the call to dev_pm_opp_set_opp() in _set_required_opps() by a call to _set_opp_level(). Moving forward we may potentially need to add support for other types of required-OPP tables. In this case, the aggregation needs to be thought of.

2024-08-23iommu: Handle iommu faults for a bad iopf setupPranjal Shrivastava
The iommu_report_device_fault function was updated to return void while assuming that drivers only need to call iommu_report_device_fault() for reporting an iopf. This implementation causes following problems: 1. The drivers rely on the core code to call it's page_reponse, however, when a fault is received and no fault capable domain is attached / iopf_param is NULL, the ops->page_response is NOT called causing the device to stall in case the fault type was PAGE_REQ. 2. The arm_smmu_v3 driver relies on the returned value to log errors returning void from iommu_report_device_fault causes these events to be missed while logging. Modify the iommu_report_device_fault function to return -EINVAL for cases where no fault capable domain is attached or iopf_param was NULL and calls back to the driver (ops->page_response) in case the fault type was IOMMU_FAULT_PAGE_REQ. The returned value can be used by the drivers to log the fault/event as needed.
