2023-11-29drm/i915: Call intel_pre_plane_updates() also for pipes getting enabledVille Syrjälä
We used to call intel_pre_plane_updates() for any pipe going through a modeset whether the pipe was previously enabled or not. This in fact needed to apply all the necessary clock gating workarounds/etc. Restore the correct behaviour.

2023-11-29drm/i915: Also check for VGA converter in eDP probeVille Syrjälä
Unfortunately even the HPD based detection added in commit cfe5bdfb27fa ("drm/i915: Check HPD live state during eDP probe") fails to detect that the VBT's eDP/DDI-A is a ghost on Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD asserted despite nothing being actually connected there :( The straps/fuses also indicate that the eDP port is present. So if one boots with a VGA monitor connected the eDP probe will mistake the DP->VGA converter hooked to DDI-E for an eDP panel on DDI-A. As a last resort check what kind of DP device we've detected, and if it looks like a DP->VGA converter then conclude that the eDP port should be ignored.

2023-11-29drm/i915/gsc: Mark internal GSC engine with reserved uabi classTvrtko Ursulin
The GSC CS is not exposed to the user, so we skipped assigning a uabi class number for it. However, the trace logs use the uabi class and instance to identify the engine, so leaving uabi class unset makes the GSC CS show up as the RCS in those logs. Given that the engine is not exposed to the user, we can't add a new case in the uabi enum, so we insted internally define a kernel internal class as -1. At the same time remove special handling for the name and complete the uabi_classes array so internal class is automatically correctly assigned. Engine will show as 65535:0 other0 in the logs/traces which should be unique enough. v2: * Fix uabi class u8 vs u16 type confusion.

Fix races between ravb_tx_timeout_work() and functions of net_device_ops and ethtool_ops by using rtnl_trylock() and rtnl_unlock(). Note that since ravb_close() is under the rtnl lock and calls cancel_work_sync(), ravb_tx_timeout_work() should calls rtnl_trylock().

__counted_by Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct PACKED_REGISTRY_TABLE`.

2023-11-28drm/tilcdc: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. There is one error path in tilcdc_pdev_remove() that potentially could yield a non-zero return code. In this case an error message describing the failure is emitted now instead of remove callback returned a non-zero value. This will be ignored. before. Otherwise there is no difference. Also note that currently tilcdc_get_external_components() doesn't return negative values.

2023-11-28devcoredump: Send uevent once devcd is readyMukesh Ojha
dev_coredumpm() creates a devcoredump device and adds it to the core kernel framework which eventually end up sending uevent to the user space and later creates a symbolic link to the failed device. An application running in userspace may be interested in this symbolic link to get the name of the failed device. In a issue scenario, once uevent sent to the user space it start reading '/sys/class/devcoredump/devcdX/failing_device' to get the actual name of the device which might not been created and it is in its path of creation. To fix this, suppress sending uevent till the failing device symbolic link gets created and send uevent once symbolic link is created successfully.

2023-11-28platform/x86: asus-wmi: disable USB0 hub on ROG Ally before suspendLuke D. Jones
ASUS have worked around an issue in XInput where it doesn't support USB selective suspend, which causes suspend issues in Windows. They worked around this by adjusting the MCU firmware to disable the USB0 hub when the screen is switched off during the Microsoft DSM suspend path in ACPI. The issue we have with this however is one of timing - the call the tells the MCU to this isn't able to complete before suspend is done so we call this in a prepare() and add a small msleep() to ensure it is done. This must be done before the screen is switched off to prevent a variety of possible races. Further to this the MCU powersave option must also be disabled as it can cause a number of issues such as: - unreliable resume connection of N-Key - complete loss of N-Key if the power is plugged in while suspended Disabling the powersave option prevents this. Without this the MCU is unable to initialise itself correctly on resume. Signed-off-by: "Luke D.

Use drm_gpuvm_bo_obtain() instead of drm_gpuvm_bo_create(). The latter should only be used in conjunction with drm_gpuvm_bo_obtain_prealloc(). drm_gpuvm_bo_obtain() re-uses existing instances of a given VM and BO combination, whereas drm_gpuvm_bo_create() would always create a new instance of struct drm_gpuvm_bo and hence leave us with duplicates.

2023-11-28r8169: prevent potential deadlock in rtl8169_closeHeiner Kallweit
ndo_stop() is RTNL-protected by net core, and the worker function takes RTNL as well. Therefore we will deadlock when trying to execute a pending work synchronously. To fix this execute any pending work asynchronously. This will do no harm because netif_running() is false in ndo_stop(), and therefore the work function is effectively a no-op. However we have to ensure that no task is running or pending after rtl_remove_one(), therefore add a call to cancel_work_sync().

2023-11-28r8169: fix deadlock on RTL8125 in jumbo mtu modeHeiner Kallweit
The original change results in a deadlock if jumbo mtu mode is used. Reason is that the phydev lock is held when rtl_reset_work() is called here, and rtl_jumbo_config() calls phy_start_aneg() which also tries to acquire the phydev lock. Fix this by calling rtl_reset_work() asynchronously.

2023-11-28efi/unaccepted: Fix off-by-one when checking for overlapping rangesMichael Roth
When a task needs to accept memory it will scan the accepting_list to see if any ranges already being processed by other tasks overlap with its range. Due to an off-by-one in the range comparisons, a task might falsely determine that an overlapping range is being accepted, leading to an unnecessary delay before it begins processing the range. Fix the off-by-one in the range comparison to prevent this and slightly improve performance.

2023-11-28octeontx2-pf: Restore TC ingress police rules when interface is upSubbaraya Sundeep
TC ingress policer rules depends on interface receive queue contexts since the bandwidth profiles are attached to RQ contexts. When an interface is brought down all the queue contexts are freed. This in turn frees bandwidth profiles in hardware causing ingress police rules non-functional after the interface is brought up. Fix this by applying all the ingress police rules config to hardware in otx2_open. Also allow adding ingress rules only when interface is running since no contexts exist for the interface when it is down.
