| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The crypto_ahb and crypto_axi clks are hardware voteable. This means that the halt bit isn't reliable because some other voter in the system, e.g. TrustZone, could be keeping the clk enabled when the kernel turns it off from clk_disable(). Make these clks use voting mode by changing the halt check to BRANCH_HALT_VOTED and toggle the voting bit in the voting register instead of directly controlling the branch by writing to the branch register. This fixes stuck clk warnings seen on ipq9574 and saves power by actually turning the clk off. Also changes the CRYPTO_AHB_CLK_ENA & CRYPTO_AXI_CLK_ENA offset to 0xb004 from 0x16014.

If a device resumes earlier than the clock controller and calls clk_prepare() when runtime PM is enabled on the controller, it will end up calling clk_pm_runtime_get(). But the subsequent pm_runtime_resume_and_get() call will fail because the runtime PM is temporarily disabled during suspend. To workaround this, introduce a need_runtime_pm flag and only enable it on mt8183-mfgcfg, which is the driver that observed deadlock previously. Hopefully mt8183-cfgcfg won't run into the issue at the resume stage because the GPU should have stopped rendering before the system calls suspend.

Currently, all of these events are exposed to userspace, even when not actually implemented. They appear in the `perf list` output, and commands like `perf stat` try to use them. This is more than just a cosmetic issue, because the PMU driver's .add function fails for these events, which causes pmu_groups_sched_in() to prematurely stop scheduling in other (possibly valid) hardware events. Add logic to check which events are supported by the hardware (i.e. can be mapped to some counter), so only usable events are reported to userspace. Since the kernel does not know the mapping between events and possible counters, this check must happen during boot, when no counters are in use. Make the check asynchronous to minimize impact on boot time.

This happens because we can't update the counter without starting it when SBI PMU extension is in use. However, the prev_count has been already updated at the first pass while the counter value is still the old one. The solution is simple where we don't need to update it again if it is already updated which can be detected using hwc state. The event state in the overflow handler is updated in the following patch. Thus, this fix can't be backported to kernel version where overflow support was added.

But imported bos attempt to grab the bo dma-resv during dma-buf detach that typically happens during cleanup. That leads to lockde splats similar to the below and a potential ABBA deadlock. Fix this by always taking the delayed workqueue cleanup path for imported bos. Requesting stable fixes from when the Xe driver was introduced, since its usage of drm_exec and wide vm dma_resvs appear to be the first reliable trigger of this.

Such big endian fb devices are usinga different pixel ordering than little endian devices, e.g. DRM_FORMAT_BGRX8888 instead of DRM_FORMAT_XRGB8888. This used to work fine as long as drm_client_buffer_addfb() was still calling drm_mode_addfb() which called drm_driver_legacy_fb_format() internally to get the right format. But drm_client_buffer_addfb() has recently been reworked to call drm_mode_addfb2() instead with the format value that has been passed to it as a parameter (see commit 6ae2ff23aa43 ("drm/client: Convert drm_client_buffer_addfb() to drm_mode_addfb2()"). That format parameter is determined in drm_fbdev_generic_helper_fb_probe() via the drm_mode_legacy_fb_format() function - which only generates formats suitable for little endian devices. So to fix this issue switch to drm_driver_legacy_fb_format() here instead to take the device endianness into consideration.

Luckily these old DTSes used nonstandard name for the property ("gpio-reset" vs "reset-gpios") so the quirk will not hurt if there are any new devices that need inverted polarity as they can specify the right polarity in their DTS when using the standard "reset-gpios" property. Additionally the condition to enable the transition from standard to non-standard reset GPIO property name was inverted and the replacement name for the property was not correct. Fix this as well.

If the current VNICs are not what is required, either too many or not enough, it will call the firmware to reserve the exact number required. There is a bug in the firmware when the driver tries to relinquish some reserved VNICs and RSS contexts. It will cause the default VNIC to lose its RSS configuration and cause receive packets to be placed incorrectly. Workaround this problem by skipping the resource reduction. The driver will not reduce the VNIC and RSS context reservations when a context is deleted. The resources will be available for use when new contexts are created later. Potentially, this workaround can cause us to run out of VNIC and RSS contexts if there are a lot of VF functions creating and deleting RSS contexts. In the future, we will conditionally disable this workaround when the firmware fix is available.

In case of any error occurred after mlxsw_linecard_types_init() call, mlxsw_linecards_init() calls mlxsw_linecard_types_fini() which performs memory deallocation again. Add pointer reset to NULL.
