Subject: [dpdk-dev] [PATCH v3 0/5] raw/ifpga/base: An improvement for multi-process
Date: Fri, 23 Oct 2020 05:06:28 -0400
Message-ID: <1603443988-7797-1-git-send-email-tianfei.zhang@intel.com> (raw)
In-Reply-To: <1600846213-18093-1-git-send-email-tianfei.zhang@intel.com>

This patches set will improve the ifpga base driver reliability in
multi-process environment.

Main changes from v2:
- Fix typo in some commit log.

Main changes from v3:
- Split into 2 small patches, one is fix the pointer variable, other is
fix the return value.
- Free the driver's resource in rawdev close ops. 

Patch #1: Fix a bug for register and unregister interrupt
functions.
Patch #2: Fix the return value of unsupported interrupt type.
Patch #3: Fix the return value of ifpga_unregister_msix_irq(), because 
rte_intr_callback_unregister() can return positive as success.
Patch #4: Clean up the ifpga resource when close the application.
Patch #5: An improvement of the concurrent in multi-process operation.
A share memory mechanism and some new mutex will be used for multi-process
protection.


Wei Huang (5):
  raw/ifpga/base: fix interrupt handler instance usage
  raw/ifpga/base: handle unsupported interrupt type
  raw/ifpga/base: fix return of IRQ unregister properly
  raw/ifpga/base: free resources when destroying ifpga device
  raw/ifpga/base: enhance driver reliablity in multi-process
