Subject: [PATCH net 0/2] net: renesas: rswitch: Fix a lot of redundant irq issue
Date: Tue, 12 Sep 2023 10:49:34 +0900	[thread overview]
Message-ID: <20230912014936.3175430-1-yoshihiro.shimoda.uh@renesas.com> (raw)

After this patch series was applied, a lot of redundant interrupts
no longer occur.

For example: when "iperf3 -c <ipaddr> -R" on R-Car S4-8 Spider
 Before the patches are applied: about 800,000 times happened
 After the patches were applied: about 100,000 times happened

Yoshihiro Shimoda (2):
  net: renesas: rswitch: Fix unmasking irq condition
  net: renesas: rswitch: Add spin lock protection for irq {un}mask
