git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc Pull char/misc fixes/removals from Greg KH: "Here's some small fixes for 5.10-rc2 and a big driver removal. The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve. But as-is, this codebase didn't work for anyone else so no actual functionality is being removed. All of these have been in linux-next with no reported issues" * tag 'char-misc-5.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: coresight: cti: Initialize dynamic sysfs attributes coresight: Fix uninitialised pointer bug in etm_setup_aux() coresight: add module license misc: mic: remove the MIC drivers interconnect: qcom: use icc_sync state for sm8[12]50 interconnect: qcom: Ensure that the floor bandwidth value is enforced interconnect: qcom: sc7180: Init BCMs before creating the nodes interconnect: qcom: sdm845: Init BCMs before creating the nodes interconnect: Aggregate before setting initial bandwidth interconnect: qcom: sdm845: Enable keepalive for the MM1 BCM

Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

2020-10-30drm/panfrost: Support cache-coherent integrationsRobin Murphy4-0/+6
When the GPU's ACE-Lite interface is fully wired up and capable of snooping CPU caches, it may be described as "dma-coherent" in devicetree, which will already inform the DMA layer not to perform unnecessary cache maintenance. However, we still need to ensure that the GPU uses the appropriate cacheable outer-shareable attributes in order to generate the requisite snoop signals, and that CPU mappings don't create a mismatch by using a non-cacheable type either.

2020-10-30iommu/io-pgtable-arm: Support coherency for Mali LPAERobin Murphy1-1/+10
Midgard GPUs have ACE-Lite master interfaces which allows systems to integrate them in an I/O-coherent manner. It seems that from the GPU's viewpoint, the rest of the system is its outer shareable domain, and so even when snoop signals are wired up, they are only emitted for outer shareable accesses. As such, setting the TTBR_SHARE_OUTER bit does indeed get coherent pagetable walks working nicely for the coherent T620 in the Arm Juno SoC.

2020-10-30vdpasim: fix MAC address configurationLaurent Vivier1-1/+2
vdpa_sim generates a ramdom MAC address but it is never used by upper layers because the VIRTIO_NET_F_MAC bit is not set in the features list. Because of that, virtio-net always regenerates a random MAC address each time it is loaded whereas the address should only change on vdpa_sim load/unload. Fix that by adding VIRTIO_NET_F_MAC in the features list of vdpa_sim.

2020-10-30vdpa: handle irq bypass register failure caseZhu Lingshan1-0/+3
LKP considered variable 'ret' in vhost_vdpa_setup_vq_irq() as a unused variable, so suggest we remove it. Actually it stores return value of irq_bypass_register_producer(), but we did not check it, we should handle the failure case. This commit will print a message if irq bypass register producer fail, in this case, vqs still remain functional.

2020-10-30usb: cdns3: gadget: own the lock wrongly at the suspend routinePeter Chen1-4/+7
When the system goes to suspend, if the controller is at device mode with cable connecting to host, the call stack is: cdns3_suspend-> cdns3_gadget_suspend -> cdns3_disconnect_gadget, after cdns3_disconnect_gadget is called, it owns lock wrongly, it causes the system being deadlock after resume due to at cdns3_device_thread_irq_handler, it tries to get the lock, but can't get it forever. To fix it, we delete the unlock-lock operations at cdns3_disconnect_gadget, and do it at the caller.

2020-10-30usb: cdns3: Fix on-chip memory overflow issuePawel Laszczak3-76/+94
Patch fixes issue caused setting On-chip memory overflow bit in usb_sts register. The issue occurred because EP_CFG register was set twice before USB_STS.CFGSTS was set. Every write operation on EP_CFG.BUFFERING causes that controller increases internal counter holding the number of reserved on-chip buffers. First time this register was updated in function cdns3_ep_config before delegating SET_CONFIGURATION request to class driver and again it was updated when class wanted to enable endpoint. This patch fixes this issue by configuring endpoints enabled by class driver in cdns3_gadget_ep_enable and others just before status stage.

2020-10-30drm/nouveau/kms/nv50-: Fix clock checking algorithm in nv50_dp_mode_valid()Lyude Paul1-10/+11
While I thought I had this correct (since it actually did reject modes like I expected during testing), Ville Syrjala from Intel pointed out that the logic here isn't correct. max_clock refers to the max data rate supported by the DP encoder. So, limiting it to the output of ds_clock (which refers to the maximum dotclock of the downstream DP device) doesn't make any sense. Additionally, since we're using the connector's bpc as the canonical BPC we should use this in mode_valid until we support dynamically setting the bpp based on bandwidth constraints. https://lists.freedesktop.org/archives/dri-devel/2020-September/280276.html For more info. So, let's rewrite this using Ville's advice. v2: * Ville pointed out I mixed up the dotclock and the link rate. So fix that... * ...and also rename all the variables in this function to be more appropriately labeled so I stop mixing them up. * Reuse the bpp from the connector for now until we have dynamic bpp selection. * Use use DIV_ROUND_UP for calculating the mode rate like i915 does, which we should also have been doing from the start Signed-off-by: Lyude Paul <lyude@redhat.com> Fixes: 409d38139b42 ("drm/nouveau/kms/nv50-: Use downstream DP clock limits for mode validation") Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lyude Paul <lyude@redhat.com> Cc: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

Ville also pointed out that I got a lot of the logic here wrong as well, whoops. While I don't think anyone's likely using 3D output with nouveau, the next patch will make nouveau_conn_mode_valid() make a lot less sense. So, let's just get rid of it and open-code it like before, while taking care to move the 3D frame packing calculations on the dot clock into the right place.

2020-10-30drm/nouveau/kms/nv50-: Program notifier offset before requesting disp capsLyude Paul6-5/+85
Not entirely sure why this never came up when I originally tested this (maybe some BIOSes already have this setup?) but the ->caps_init vfunc appears to cause the display engine to throw an exception on driver init, at least on my ThinkPad P72: nouveau 0000:01:00.0: disp: chid 0 mthd 008c data 00000000 0000508c 0000102b This is magic nvidia speak for "You need to have the DMA notifier offset programmed before you can call NV507D_GET_CAPABILITIES." So, let's fix this by doing that, and also perform an update afterwards to prevent racing with the GPU when reading capabilities. v2: * Don't just program the DMA notifier offset, make sure to actually perform an update v3: * Don't call UPDATE() * Actually read the correct notifier fields, as apparently the CAPABILITIES_DONE field lives in a different location than the main NV_DISP_CORE_NOTIFIER_1 field. As well, 907d+ use a different CAPABILITIES_DONE field then pre-907d cards. v4: * Don't forget to check the return value of core507d_read_caps() v5: * Get rid of NV50_DISP_CAPS_NTFY[14], use NV50_DISP_CORE_NTFY * Disable notifier after calling GetCapabilities() Signed-off-by: Lyude Paul <lyude@redhat.com> Fixes: 4a2cb4181b07 ("drm/nouveau/kms/nv50-: Probe SOR and PIOR caps for DP interlacing support") Cc: <stable@vger.kernel.org> # v5.8+ Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2020-10-30scsi: target: tcmu: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].
