[PATCH 00/14] staging: unisys: add channel interrupt support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series adds a centralized infrastructure and device support
for channel interrupts sent to s-Par virtual devices. With these changes,
the visorhba device is ~80% faster than with only polling, and visornic
receives a speedup of over 3500% (from ~9Mb/s to between 360Mb/s and
390Mb/s).

David Kershner (13):
  staging: unisys: Change poll rate to 2 ms for work
  staging: unisys: set client state
  staging: unisys: visorhba: Convert visorhba to use visorbus channel
    interrupts.
  staging: unisys: Convert visornic to use visorbus channel interrupt
    code
  staging: unisys: Only process up to budget amount of responses
  staging: unisys: Add support to update Features bits in channel queues
  staging: unisys: Add channel feature access functions
  staging: unisys: Re-enable interrupts after we have done the work
  staging: unisys: Capture data from device create to register
    interrupt.
  staging: unisys: Don't go into POLLING mode in visornic_probe.
  staging: unisys: Don't set polling mode in visorhba_probe
  staging: unisys: Remove semaphores around channel interrupts.
  staging: unisys: Allow for unregistering of interrupts.

Tim Sell (1):
  staging: unisys: visorinput: use spinlock for channel_interrupt()
    locking
