2024-06-27drm/amd/display: Remove unnecessary variableIvan Lipski
[WHY] Coverity analysis flagged this code as DEADCODE because the condition '(!need_recovery)' is never true. The variable 'need_recovery' is initialized as 'true', is not assigned to 'false' anywhere before the conditional statement. Since the variable is only used for the conditional check, but the check can never be true, the variable itself is redundant. [HOW] Removed the variable 'need_recovery'.

[WHY] Coverity analysis flagged these files as containing DEADCODE, i. e. redundant or unreachabale. In these files, variable 'mode_422' is always the same file (0 or false), so any code logic with it is redundant.

2024-06-27drm/amd/display: Refactor dccg401_get_other_enable_symclk_feRelja Vojvodic
[WHY] Function was used to check the number of FEs connected to the current BE. This was then used to determine if the symclk could be disabled, if all FEs were disconnected. However, the function would skip over the primary FE and return 0 when the primary FE was still connected. This caused black screens on driver disable with an MST daisy chain hooked up. [HOW] Refactored the function to correctly return the number of FEs connected to the input BE. Also renamed it for clarity.

2024-06-27kallsyms: rework symbol lookup return codesArnd Bergmann
Building with W=1 in some configurations produces a false positive warning for kallsyms: kernel/kallsyms.c: In function '__sprint_symbol.isra': kernel/kallsyms.c:503:17: error: 'strcpy' source argument is the same as destination [-Werror=restrict] 503 | strcpy(buffer, name); | ^~~~~~~~~~~~~~~~~~~~ This originally showed up while building with -O3, but later started happening in other configurations as well, depending on inlining decisions. The underlying issue is that the local 'name' variable is always initialized to the be the same as 'buffer' in the called functions that fill the buffer, which gcc notices while inlining, though it could see that the address check always skips the copy. The calling conventions here are rather unusual, as all of the internal lookup functions (bpf_address_lookup, ftrace_mod_address_lookup, ftrace_func_address_lookup, module_address_lookup and kallsyms_lookup_buildid) already use the provided buffer and either return the address of that buffer to indicate success, or NULL for failure, but the callers are written to also expect an arbitrary other buffer to be returned. Rework the calling conventions to return the length of the filled buffer instead of its address, which is simpler and easier to follow as well as avoiding the warning. Leave only the kallsyms_lookup() calling conventions unchanged, since that is called from 16 different functions and adapting this would be a much bigger change.

2024-06-27gpiolib: cdev: Ignore reconfiguration without directionKent Gibson
linereq_set_config() behaves badly when direction is not set. The configuration validation is borrowed from linereq_create(), where, to verify the intent of the user, the direction must be set to in order to effect a change to the electrical configuration of a line. But, when applied to reconfiguration, that validation does not allow for the unset direction case, making it possible to clear flags set previously without specifying the line direction. Adding to the inconsistency, those changes are not immediately applied by linereq_set_config(), but will take effect when the line value is next get or set. For example, by requesting a configuration with no flags set, an output line with GPIO_V2_LINE_FLAG_ACTIVE_LOW and GPIO_V2_LINE_FLAG_OPEN_DRAIN set could have those flags cleared, inverting the sense of the line and changing the line drive to push-pull on the next line value set. Skip the reconfiguration of lines for which the direction is not set, and only reconfigure the lines for which direction is set.

Ensure the intent of the user by disallowing configurations which do not have direction set, returning an error to userspace to indicate that the configuration is invalid. And, for clarity, use lflags, a local copy of gcnf.flags, throughout when dealing with the requested flags, rather than a mixture of both.

2024-06-27Revert "usb: gadget: u_ether: Replace netif_stop_queue with netif_device_detach"Ferry Toth
This reverts commit f49449fbc21e7e9550a5203902d69c8ae7dfd918. This commit breaks u_ether on some setups (at least Merrifield). The fix "usb: gadget: u_ether: Re-attach netif device to mirror detachment" party restores u-ether. However the netif usb: remains up even usb is switched from device to host mode. This creates problems for user space as the interface remains in the routing table while not realy present and network managers (connman) not detecting a network change. Various attempts to find the root cause were unsuccesful up to now. Therefore revert until a solution is found.

2024-06-27drm/mediatek: Call drm_atomic_helper_shutdown() at shutdown timeDouglas Anderson
Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c. This driver users the component model and shutdown happens in the base driver. The "drvdata" for this driver will always be valid if shutdown() is called and as of commit 2a073968289d ("drm/atomic-helper: drm_atomic_helper_shutdown(NULL) should be a noop") we don't need to confirm that "drm" is non-NULL.

2024-06-27drm/i915/dsb: Try to document that DSB_STATUS bit 16 is level triggeredVille Syrjälä
DSB_STATUS bit 16 is supposed to be a sticky bit informing us whether the DSB was idle or not when the pipe's delayed vblank (when double buffered registers latch) occurred. Unfortunately it turns out this is a level triggred signal, ie. the bit will be set whenever the DSB is busy during the scanline window between start of delayed vblank and vtotal. Try to document that fact by renaming the bit. Sadly this also thwarts my plan to use this bit to sanity check that the (to be introduced) DSB based vblank evasion did its job correctly. That would require an edge triggered signal instead. So looks like we'll have to rely mostly on luck instead :( Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240611133344.30673-12-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>

2024-06-27iommu/amd: Fix GT feature enablement againVasant Hegde
Current code configures GCR3 even when device is attached to identity domain. So that we can support SVA with identity domain. This means in attach device path it updates Guest Translation related bits in DTE. Commit de111f6b4f6a ("iommu/amd: Enable Guest Translation after reading IOMMU feature register") missed to enable Control[GT] bit in resume path. Its causing certain laptop to fail to resume after suspend. This is because we have inconsistency between between control register (GT is disabled) and DTE (where we have enabled guest translation related bits) in resume path. And IOMMU hardware throws ILLEGAL_DEV_TABLE_ENTRY. Fix it by enabling GT bit in resume path.

2024-06-27iommu/vt-d: Fix missed device TLB cache tagLu Baolu
When a domain is attached to a device, the required cache tags are assigned to the domain so that the related caches can be flushed whenever it is needed. The device TLB cache tag is created based on whether the ats_enabled field of the device's iommu data is set. This creates an ordered dependency between cache tag assignment and ATS enabling. The device TLB cache tag would not be created if device's ATS is enabled after the cache tag assignment. This causes devices with PCI ATS support to malfunction. The ATS control is exclusively owned by the iommu driver. Hence, move cache_tag_assign_domain() after PCI ATS enabling to make sure that the device TLB cache tag is created for the domain.

2024-06-27iommu/amd: Invalidate cache before removing device from domain listVasant Hegde
Commit 87a6f1f22c97 ("iommu/amd: Introduce per-device domain ID to fix potential TLB aliasing issue") introduced per device domain ID when domain is configured with v2 page table. And in invalidation path, it uses per device structure (dev_data->gcr3_info.domid) to get the domain ID. In detach_device() path, current code tries to invalidate IOMMU cache after removing dev_data from domain device list. This means when domain is configured with v2 page table, amd_iommu_domain_flush_all() will not be able to invalidate cache as device is already removed from domain device list. This is causing change domain tests (changing domain type from identity to DMA) to fail with IO_PAGE_FAULT issue. Hence invalidate cache and update DTE before updating data structures.
