2023-06-12RDMA/bnxt_re: Avoid the command wait if firmware is inactiveKashyap Desai
Add a check to avoid waiting if driver already detects a FW timeout. Return success for resource destroy in case the device is detached. Add helper function to map timeout error code to success.

2023-06-12RDMA/bnxt_re: Enhance the existing functions that wait for FW responsesKashyap Desai
Use jiffies based timewait instead of counting iteration for commands that block for FW response. Also add a poll routine for control path commands. This is for polling completion if the waiting commands timeout. This avoids cases where the driver misses completion interrupts.

2023-06-12RDMA/bnxt_re: wraparound mbox producer indexKashyap Desai
Driver is not handling the wraparound of the mbox producer index correctly. Currently the wraparound happens once u32 max is reached. Bit 31 of the producer index register is special and should be set only once for the first command. Because the producer index overflow setting bit31 after a long time, FW goes to initialization sequence and this causes FW hang. Fix is to wraparound the mbox producer index once it reaches u16 max.

bnxt_re currently uses the names "bnxt_qplib_creq" and "bnxt_qplib_nq-0" while registering IRQs. There is no way to distinguish the IRQs of different device ports when there are multiple IB devices registered. This could make the scenarios worse where one want to pin IRQs of a device port to certain CPUs. Fixed the code to use unique names which has PCI BDF information while registering interrupts like: "bnxt_re-nq-0@pci:0000:65:00.0" and "bnxt_re-creq@pci:0000:65:00.1".

2023-05-19RDMA/bnxt_re: Disable/kill tasklet only if it is enabledSelvin Xavier
When the ulp hook to start the IRQ fails because the rings are not available, tasklets are not enabled. In this case when the driver is unloaded, driver calls CREQ tasklet_kill. This causes an indefinite hang as the tasklet is not enabled. Driver shouldn't call tasklet_kill if it is not enabled. So using the creq->requested and nq->requested flags to identify if both tasklets/irqs are registered. Checking this flag while scheduling the tasklet from ISR. Also, added a cleanup for disabling tasklet, in case request_irq fails during start_irq. Check for return value for bnxt_qplib_rcfw_start_irq and in case the bnxt_qplib_rcfw_start_irq fails, return bnxt_re_start_irq without attempting to start NQ IRQs.

2022-04-06RDMA: Split kernel-only global device caps from uverbs device capsJason Gunthorpe
Split out flags from ib_device::device_cap_flags that are only used internally to the kernel into kernel_cap_flags that is not part of the uapi. This limits the device_cap_flags to being the same bitmap that will be copied to userspace. This cleanly splits out the uverbs flags from the kernel flags to avoid confusion in the flags bitmap. Add some short comments describing which each of the kernel flags is connected to. Remove unused kernel flags.

2021-11-25RDMA/bnxt_re: Remove dynamic pkey tableKamal Heib
The RoCE spec requires RoCE devices to support only the default pkey. However the bnxt_re driver maintains a 0xFFFF entry pkey table and uses only the first entry. Remove the pkey table and hard code a table of length one hard wired with the default pkey.

pending cmd-bit" The 'cmdq->cmdq_bitmap' bitmap is 'rcfw->cmdq_depth' bits long. The size stored in 'cmdq->bmap_size' is the size of the bitmap in bytes. Remove this erroneous 'bmap_size' and use 'rcfw->cmdq_depth' directly in 'bnxt_qplib_disable_rcfw_channel()'. Otherwise some error messages may be missing. Other uses of 'cmdq_bitmap' already take into account 'rcfw->cmdq_depth' directly.
