2019-04-14drm/amd/display: If one stream full updates, full update all planesDavid Francis2-0/+22
[Why] On some compositors, with two monitors attached, VT terminal switch can cause a graphical issue by the following means: There are two streams, one for each monitor. Each stream has one plane current state: M1:S1->P1 M2:S2->P2 The user calls for a terminal switch and a commit is made to change both planes to linear swizzle mode. In atomic check, a new dc_state is constructed with new planes on each stream new state: M1:S1->P3 M2:S2->P4 In commit tail, each stream is committed, one at a time. The first stream (S1) updates properly, triggerring a full update and replacing the state current state: M1:S1->P3 M2:S2->P4 The update for S2 comes in, but dc detects that there is no difference between the stream and plane in the new and current states, and so triggers a fast update. The fast update does not program swizzle, so the second monitor is corrupted [How] Add a flag to dc_plane_state that forces full updates When a stream undergoes a full update, set this flag on all changed planes, then clear it on the current stream Subsequent streams will get full updates as a result Signed-off-by: David Francis <[email protected]> Signed-off-by: Nicholas Kazlauskas <[email protected]> Reviewed-by: Roman Li <[email protected]> Acked-by: Bhawanpreet Lakha <Bhawanpreet [email protected]> Acked-by: Nicholas Kazlauskas <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

2019-04-14qed: Fix the DORQ's attentions handlingDenis Bolotin2-16/+48
Separate the overflow handling from the hardware interrupt status analysis. The interrupt status is a single register and is common for all PFs. The first PF reading the register is not necessarily the one who overflowed. All PFs must check their overflow status on every attention. In this change we clear the sticky indication in the attention handler to allow doorbells to be processed again as soon as possible, but running the doorbell recovery is scheduled for the periodic handler to reduce the time spent in the attention handler. Checking the need for DORQ flush was changed to "db_bar_no_edpm" because qed_edpm_enabled()'s result could change dynamically and might have prevented a needed flush.

2019-04-14qed: Fix missing DORQ attentionsDenis Bolotin3-3/+20
When the DORQ (doorbell block) is overflowed, all PFs get attentions at the same time. If one PF finished handling the attention before another PF even started, the second PF might miss the DORQ's attention bit and not handle the attention at all. If the DORQ attention is missed and the issue is not resolved, another attention will not be sent, therefore each attention is treated as a potential DORQ attention. As a result, the attention callback is called more frequently so the debug print was moved to reduce its quantity. The number of periodic doorbell recovery handler schedules was reduced because it was the previous way to mitigating the missed attention issue.

DB_REC_DRY_RUN (running doorbell recovery without sending doorbells) is never used. DB_REC_ONCE (send a single doorbell from the doorbell recovery) is not needed anymore because by running the periodic handler we make sure we check the overflow status later instead. This patch is needed because in the next patches, the only doorbell recovery type being used is DB_REC_REAL_DEAL, and the fixes are much cleaner without this enum.

In original codes, ndo_set_vf_vlan() in hns3 driver was implemented wrong. It adds or removes VLAN into VLAN filter for VF, but VF is unaware of it. This patch fixes it. When VF loads up, it firstly queries the port based VLAN state from PF. When user change port based VLAN state from PF, PF firstly checks whether the VF is alive. If the VF is alive, then PF notifies the VF the modification; otherwise PF configure the port based VLAN state directly.

In original codes, ndo_set_vf_vlan() in hns3 driver was implemented wrong. It adds or removes VLAN into VLAN filter for VF, but VF is unaware of it. Indeed, ndo_set_vf_vlan() is expected to enable or disable port based VLAN (hardware inserts a specified VLAN tag to all TX packets for a specified VF) . When enable port based VLAN, we use port based VLAN id as VLAN filter entry. When disable port based VLAN, we use VLAN id of VLAN device.

2019-04-14net: hns3: fix VLAN offload handle for VLAN inserted by portJian Shen3-4/+52
Currently, in TX direction, driver implements the TX VLAN offload by checking the VLAN header in skb, and filling it into TX descriptor. Usually it works well, but if enable inserting VLAN header based on port, it may conflict when out_tag field of TX descriptor is already used, and cause RAS error. In RX direction, hardware supports stripping max two VLAN headers. For vlan_tci in skb can only store one VLAN tag, when RX VLAN offload enabled, driver tells hardware to strip one VLAN header from RX packet; when RX VLAN offload disabled, driver tells hardware not to strip VLAN header from RX packet. Now if port based insert VLAN enabled, all RX packets will have the port based VLAN header. This header is useless for stack, driver needs to ask hardware to strip it. Unfortunately, hardware can't drop this VLAN header, and always fill it into RX descriptor, so driver has to identify and drop it.

2019-04-14net: hns3: modify VLAN initialization to be compatible with port based VLANJian Shen3-30/+78
Our hardware supports inserting a specified VLAN header for each function when sending packets. User can enable it with command "ip link set <devname> vf <vfid> vlan <vlan id>". For this VLAN header is inserted by hardware, not from stack, hardware also needs to strip it from received packets before sending to stack. In this case, driver needs to tell hardware which VLAN to insert or strip. The current VLAN initialization doesn't allow inserting VLAN header by hardware, this patch modifies it, in order be compatible with VLAN inserted base on port.

2019-04-13brcmfmac: Use struct_size() in kzalloc()Gustavo A. R. Silva1-3/+1
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL) Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL) Notice that, in this case, variable reqsz is not necessary, hence it is removed.

2019-04-12nfp: add a mutex lock for the vNIC ctrl BARJakub Kicinski4-23/+87
Soon we will try to write to the vNIC mailbox without RTNL held. Add a new mutex to protect access to specific parts of the PCI control BAR. Move the mailbox size checking to the mailbox lock() helper, where it can be more effective (happen prior to potential overwrite of other data).

2019-04-12qede: fix write to free'd pointer error and double free of ptpColin Ian King1-4/+3
The err2 error return path calls qede_ptp_disable that cleans up on an error and frees ptp. After this, the free'd ptp is dereferenced when ptp->clock is set to NULL and the code falls-through to error path err1 that frees ptp again. Fix this by calling qede_ptp_disable and exiting via an error return path that does not set ptp->clock or kfree ptp.

2019-04-12vxge: fix return of a free'd memblock on a failed dma mappingColin Ian King1-0/+1
Currently if a pci dma mapping failure is detected a free'd memblock address is returned rather than a NULL (that indicates an error). Fix this by ensuring NULL is returned on this error case.

2019-04-12netdevsim: make bpf_offload_dev_create() per-sdev instead of first nsJiri Pirko1-12/+14
offload dev is stored in sdev struct. However, first netdevsim instance is used as a priv. Change this to be sdev to as it is shared among multiple netdevsim instances. Signed-off-by: Jiri Pirko <[email protected]> Signed-off-by: David S. Miller <[email protected]>
