2021-09-27IB/hfi1: Remove cache and embed txreq in ringMike Marciniszyn
This patch removes kmem cache allocation and deallocation in favor of having the ipoib_txreq in the ring. The consumer is now the packet sending side allocating tx descriptors from ring and the producer is the napi interrupt handling freeing tx descriptors. The locks are now eliminated because the napi tx lock insures a single consumer and the napi handling insures a single producer. The napi poll is converted to memory poll looking for items that have been marked completed.

2021-09-24RDMA/rxe: Only allow invalidate for appropriate MRsBob Pearson
Local and remote invalidate operations are not allowed by IBA for MRs created by (re)register memory verbs. This patch checks the MR type in rxe_invalidate_mr().

2021-09-24RDMA/rxe: Create duplicate mapping tables for FMRsBob Pearson
For fast memory regions create duplicate mapping tables so ib_map_mr_sg() can build a new mapping table which is then swapped into place synchronously with the execution of an IB_WR_REG_MR work request. Currently the rxe driver uses the same table for receiving RDMA operations and for building new tables in preparation for reusing the MR. This exposes users to potentially incorrect results.

2021-09-24RDMA/rxe: Separate HW and SW l/rkeysBob Pearson
Separate software and simulated hardware lkeys and rkeys for MRs and MWs. This makes struct ib_mr and struct ib_mw isolated from hardware changes triggered by executing work requests.

2021-09-24RDMA/rxe: Add memory barriers to kernel queuesBob Pearson
Earlier patches added memory barriers to protect user space to kernel space communications. The user space queues were previously shown to have occasional memory synchonization errors which were removed by adding smp_load_acquire, smp_store_release barriers. This patch extends that to the case where queues are used between kernel space threads. This patch also extends the queue types to include kernel ULP queues which access the other end of the queues in kernel verbs calls like poll_cq and post_send/recv.

2021-09-20RDMA/bnxt_re: Fix FRMR issue with single page MR allocationSelvin Xavier
When the FRMR is allocated with single page, driver is attempting to create a level 0 HWQ and not allocating any page because the nopte field is set. This causes the crash during post_send as the pbl is not populated. To avoid this crash, check for the nopte bit during HWQ creation with single page and create a level 1 page table and populate the pbl address correctly.

2021-09-20RDMA/bnxt_re: Reduce the delay in polling for hwrm command completionSelvin Xavier
Driver has 1ms delay between the polling for atomic command completion. Polling immediately after issuing command usually doesn't report any completions. So all commands in the blocking path needs two iterations. So effectively 1ms spend on each command. HW requires much lesser time for each command. So reduce the delay to 1us and increase the iteration count to wait for the same time.

2021-09-10of: property: Disable fw_devlink DT support for X86Saravana Kannan
Andre reported fw_devlink=on breaking OLPC XO-1.5 [1]. OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate devices. The root cause seems to be ISA devices not setting their fwnode field. But trying to figure out how to fix that doesn't seem worth the trouble because the OLPC devicetree is very sparse/limited and fw_devlink only adds the links causing this issue. Considering that there aren't many users of OF in an X86 system, simply fw_devlink DT support for X86.

2021-09-10drm/ttm: Fix a deadlock if the target BO is not idle during swapxinhui pan
The ret value might be -EBUSY, caller will think lru lock is still locked but actually NOT. So return -ENOSPC instead. Otherwise we hit list corruption. ttm_bo_cleanup_refs might fail too if BO is not idle. If we return 0, caller(ttm_tt_populate -> ttm_global_swapout ->ttm_device_swapout) will be stuck as we actually did not free any BO memory. This usually happens when the fence is not signaled for a long time.
