2021-11-24drm/amdgpu: enable Navi 48-bit IH timestamp counterPhilip Yang1-0/+1
By default this timestamp is 32 bit counter. It gets overflowed in around 10 minutes. Signed-off-by: Philip Yang <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
2021-11-24drm/amdkfd: simplify drain retry faultPhilip Yang2-9/+23
unmap range always increase atomic svms->drain_pagefaults to simplify both parent range and child range unmap, page fault handle ignores the retry fault if svms->drain_pagefaults is set to speed up interrupt handling. svm_range_drain_retry_fault restart draining if another range unmap from cpu.

2021-11-24drm/amdkfd: handle VMA remove racePhilip Yang1-9/+13
VMA may be removed before unmap notifier callback, and deferred list work remove range, return success for this special case as we are handling stale retry fault.

2021-11-24drm/amdkfd: process exit and retry fault racePhilip Yang1-27/+36
kfd_process_wq_release drain retry fault to ensure no retry fault comes after removing kfd process from the hash table, otherwise svm page fault handler will fail to recover the fault and dump GPU vm fault log. Refactor deferred list work to get_task_mm and take mmap write lock to handle all ranges, and avoid mm is gone while inserting mmu notifier.

2021-11-24drm/amdgpu: move kfd post_reset out of reset_sriov functionshaoyunl1-4/+3
Fixes: 9f4f2c1a3524 ("drm/amd/amdgpu: fix the kfd pre_reset sequence in sriov") For sriov XGMI configuration, the host driver will handle the hive reset, so in guest side, the reset_sriov only be called once on one device. This will make kfd post_reset unblanced with kfd pre_reset since kfd pre_reset already been moved out of reset_sriov function. Move kfd post_reset out of reset_sriov function to make them balance .

2021-11-24drm/amd/display: Reset link encoder assignments for GPU resetNicholas Kazlauskas1-0/+14
[Why] A warning appears in the log on GPU reset for link_enc_cfg_link_encs_assign for the following condition: ASSERT(state->res_ctx.link_enc_cfg_ctx.link_enc_assignments[i].valid == false); This is not expected behavior and may result in link encoders being incorrectly assigned. [How] The dc->current_state is backed up into dm->cached_dc_state before we commit 0 streams. DC will clear link encoder assignments on the real state but the changes won't propagate over to the copy we made before the 0 streams commit. DC expects that link encoder assignments are *not* valid when committing a state, so as a workaround it needs to be cleared before passing it back into DC.

2021-11-24drm/amd/display: Set plane update flags for all planes in resetNicholas Kazlauskas1-2/+2
[Why] We're only setting the flags on stream[0]'s planes so this logic fails if we have more than one stream in the state. This can cause a page flip timeout with multiple displays in the configuration. [How] Index into the stream_status array using the stream index - it's a 1:1 mapping.

2021-11-24drm/amd/display: Fix DPIA outbox timeout after GPU resetNicholas Kazlauskas1-0/+2
[Why] The HW interrupt gets disabled after GPU reset so we don't receive notifications for HPD or AUX from DMUB - leading to timeout and black screen with (or without) DPIA links connected.

2021-11-24xen: detect uninitialized xenbus in xenbus_initStefano Stabellini1-0/+23
If the xenstore page hasn't been allocated properly, reading the value of the related hvm_param (HVM_PARAM_STORE_PFN) won't actually return error. Instead, it will succeed and return zero. Instead of attempting to xen_remap a bad guest physical address, detect this condition and return early. Note that although a guest physical address of zero for HVM_PARAM_STORE_PFN is theoretically possible, it is not a good choice and zero has never been validly used in that capacity. Also recognize all bits set as an invalid value. For 32-bit Linux, any pfn above ULONG_MAX would get truncated. Pfns above ULONG_MAX should never be passed by the Xen tools to HVM guests anyway, so check for this condition and return early.

Non-essential devices are identified by their nodenames directly in the xenbus driver, which requires to update this list in case a new device type being non-essential is added (this was missed for several types in the past). In order to avoid this problem, add a "not_essential" flag to struct xenbus_driver which can be set to "true" by the respective frontend.

Printk modifier %pfw is used to print the full path of the device name. This is obtained device by device until a device no longer has a parent. On ACPI getting the parent fwnode is done by calling acpi_get_parent() which tries to down() a semaphore. But local IRQs are now disabled in vprintk_store() before the mutex is acquired. This is obviously a problem. Luckily struct device, embedded in struct acpi_device, has a parent field already. Use that field to get the parent instead of relying on acpi_get_parent().

2021-11-23net: ipa: kill ipa_cmd_pipeline_clear()Alex Elder3-24/+0
Calling ipa_cmd_pipeline_clear() after stopping the channel underlying the AP<-modem RX endpoint can lead to a deadlock. This occurs in the ->runtime_suspend device power operation for the IPA driver. While this callback is in progress, any other requests for power will block until the callback returns. Stopping the AP<-modem RX channel does not prevent the modem from sending another packet to this endpoint. If a packet arrives for an RX channel when the channel is stopped, an SUSPEND IPA interrupt condition will be pending. Handling an IPA interrupt requires power, so ipa_isr_thread() calls pm_runtime_get_sync() first thing. The problem occurs because a "pipeline clear" command will not complete while such a SUSPEND interrupt condition exists. So the SUSPEND IPA interrupt handler won't proceed until it gets power; that won't happen until the ->runtime_suspend callback (and its "pipeline clear" command) completes; and that can't happen while the SUSPEND interrupt condition exists. It turns out that in this case there is no need to use the "pipeline clear" command. There are scenarios in which clearing the pipeline is required while suspending, but those are not (yet) supported upstream. So a simple fix, avoiding the potential deadlock, is to stop calling ipa_cmd_pipeline_clear() in ipa_endpoint_suspend(). This removes the only user of ipa_cmd_pipeline_clear(), so get rid of that function. It can be restored again whenever it's needed. This is basically a manual revert along with an explanation for commit 6cb63ea6a39ea ("net: ipa: introduce ipa_cmd_tag_process()").

device is opened and closed, it should be stopping and starting the PHY. The phy should be connected as part of binding and disconnected during unbinding. As this results in the PHY not being reset during open, link speed, etc. settings set prior to the link coming up are now not being lost. It is necessary for phy_stop() to only be called when the phydev still exists (resolving the above stack trace). When unbinding, ".unbind" will be called prior to ".stop", with phy_disconnect() already having called phy_stop() before the phydev becomes inaccessible.

2021-11-23net: chelsio: cxgb4vf: Fix an error code in cxgb4vf_pci_probe()Zheyu Ma1-0/+1
During the process of driver probing, probe function should return < 0 for failure, otherwise kernel will treat value == 0 as success. Therefore, we should set err to -EINVAL when adapter->registered_device_map is NULL. Otherwise kernel will assume that driver has been successfully probed and will cause unexpected errors.

The original changes brakes MAC address assignment on older chip versions (see bug report [0]), and it brakes random MAC assignment. is_valid_ether_addr() requires that its argument is word-aligned. Add the missing alignment to array mac_addr.
