2021-11-10net: hns3: allow configure ETS bandwidth of all TCsGuangbin Huang
Currently, driver only allow configuring ETS bandwidth of TCs according to the max TC number queried from firmware. However, the hardware actually supports 8 TCs and users may need to configure ETS bandwidth of all TCs, so remove the restriction.

2021-11-10net: hns3: remove check VF uc mac exist when set by PFGuangbin Huang
If users set unicast mac address for VFs by PF, they need to guarantee all VFs' address is different. This patch removes the check mac address exist of VFs, for usrs can refresh mac addresses of all VFs directly without need to modify the exist mac address to other value firstly.

2021-11-10net: hns3: fix some mac statistics is always 0 in device version V2Guangbin Huang
When driver queries the register number of mac statistics from firmware, the old firmware runs in device version V2 only returns number of valid registers, not include number of three reserved registers among of them. It cause driver doesn't record the last three data when query mac statistics. To fix this problem, driver never query register number in device version V2 and set it to a fixed value which include three reserved registers.

When fully configure VLANs for a VF, then unload the VF while triggering a reset to PF, will cause a kernel crash because the irq is already uninit.

2021-11-10net: hns3: sync rx ring head in echo common pullYufeng Mo
When the driver processes rx packets, the head pointer is updated only after the number of received packets reaches 16. However, hardware relies on the head pointer to calculate the number of FBDs. As a result, the hardware calculates the FBD incorrectly. Therefore, the driver proactively updates the head pointer in each common poll to ensure that the number of FBDs calculated by the hardware is correct.

2021-11-10net: hns3: fix pfc packet number incorrect after querying pfc parametersJie Wang
Currently, driver will send command to firmware to query pfc packet number when user uses dcb tool to get pfc parameters. However, the periodic service task will also periodically query and record MAC statistics, including pfc packet number. As the hardware registers of statistics is cleared after reading, it will cause pfc packet number of MAC statistics are not correct after using dcb tool to get pfc parameters. To fix this problem, when user uses dcb tool to get pfc parameters, driver updates MAC statistics firstly and then get pfc packet number from MAC statistics.

2021-11-10net: hns3: fix failed to add reuse multicast mac addr to hardware when mc ↵Guangbin Huang
mac table is full Currently, when driver is failed to add a new multicast mac address to hardware due to the multicast mac table is full, it will directly return. In this case, if the multicast mac list has some reuse addresses after the new address, those reuse addresses will never be added to hardware. To fix this problem, if function hclge_add_mc_addr_common() returns -ENOSPC, hclge_sync_vport_mac_list() should judge whether continue or stop to add next address. As function hclge_sync_vport_mac_list() needs parameter mac_type to know whether is uc or mc, refine this function to add parameter mac_type and remove parameter sync. So does function hclge_unsync_vport_mac_list(). Fixes: ee4bcd3b7ae4 ("net: hns3: refactor the MAC address configure") Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S.

2021-11-09Input: ili210x - reduce sample period to 15msMarek Vasut
Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom.

2021-11-09Input: ili210x - improve polled sample spacingMarek Vasut
Currently the ili210x driver implements a threaded interrupt handler which starts upon edge on the interrupt line, and then polls the touch controller for samples. Every time a sample is obtained from the controller, the thread function checks whether further polling is required, and if so, waits fixed amount of time before polling for next sample. The delay between consecutive samples can thus vary greatly, because the I2C transfer required to retrieve the sample from the controller takes different amount of time on different platforms. Furthermore, different models of the touch controllers supported by this driver require different delays during retrieval of samples too. Instead of waiting fixed amount of time before polling for next sample, determine how much time passed since the beginning of sampling cycle and then wait only the remaining amount of time within the sampling cycle. This makes the driver deliver samples with equal spacing between them.

2021-11-09amt: use cancel_delayed_work() instead of flush_delayed_work() in amt_fini()Taehee Yoo
When the amt module is being removed, it calls flush_delayed_work() to exit source_gc_wq. But it wouldn't be exited properly because the amt_source_gc_work(), which is the callback function of source_gc_wq internally calls mod_delayed_work() again. So, amt_source_gc_work() would be called after the amt module is removed. Therefore kernel panic would occur. In order to avoid it, cancel_delayed_work() should be used instead of flush_delayed_work().

Tell the RTC core UIE are not supported because the resolution of the alarm is a minute. Note that this is in fact also fixing how the resolution is reported as the previous test was simply ensuring the alarm was more than a minute in the future while the register has a minute resolution. This would be ok if the alarm was a countdown but ab8500_rtc_read_alarm suggests otherwise and the AB8500 datasheet states that the RTC documentation is not public. Finally, the comment is wrong and what makes the UIE emulation work is uie_unsupported being set.

2021-11-09drm/amd/display: Add callbacks for DMUB HPD IRQ notificationsNicholas Kazlauskas
[Why] We need HPD IRQ notifications (RX, short pulse) to properly handle DP MST for DPIA connections. [How] A null pointer exception currently occurs when these are received so add a check to validate that we have a handler installed for the notification. Extend the HPD handler to also handle HPD IRQ (RX) since the logic is the same.

2021-11-09drm/amd/display: Don't lock connection_mutex for DMUB HPDNicholas Kazlauskas
[Why] Per DRM spec we only need to hold that lock when touching connector->state - which we do not do in that handler. Taking this locking introduces unnecessary dependencies with other threads which is bad for performance and opens up the potential for a deadlock since there are multiple locks being held at once. [How] Remove the connection_mutex lock/unlock routine and just iterate over the drm connectors normally. The iter helpers implicitly lock the connection list so this is safe to do. DC link access also does not need to be guarded since the link table is static at creation - we don't dynamically add or remove links, just streams.

2021-11-09drm/amdkfd: Fix retry fault drain race conditionsFelix Kuehling
The check for whether to drain retry faults must be under the mmap write lock to serialize with munmap notifier callbacks. We were also missing checks on child ranges. To fix that, simplify the logic by using a flag rather than checking on each prange. That also allows draining less freqeuntly when many ranges are unmapped at once.

2021-11-09drm/amdkfd: lower the VAs base offset to 8KBAlex Sierra
The low 16MB of virtual address space are currently reserved for kernel mode allocations mapped into user virtual address space. This causes conflicts with HMM/SVM mappings at low virtual addresses. We tried to move those kernel mode allocations to the upper half of the 64-bit virtual address space for GFX9, which is naturally reserved for kernel use. However, TBA (trap handler code) has problems to access addresses in the high virtual space. We have decided to set this to 8KB of the lower address space as a temporary fix, while investigate TBA address problem. It is very unlikely for user space to map memory at this low region.
