Subject: [ath9k-devel] Atheros 9390 and AR_INTR_SYNC_HOST1_PERR
Date: Wed, 07 Dec 2011 12:06:32 +0100 [thread overview]
Message-ID: <4EDF48B8.4050706@gmx.de> (raw)
Hallo,
we use a mini PCIe card (9390) with a miniPCe to PCIe adapter on a X86
system and a system with a Xilinix Microblaze CPU.
As the performance on the Microblaze is bad (ping times up to 10 sec),
we examined the interrupt service routine.
On Microblaze *and* on X86 we see about 10 "spurious" interrupts per
second.
In this cases in ar9003_hw_get_isr (ar9003_mac.c) the sync_cause bit
"AR_INTR_SYNC_HOST1_PERR" is set.
The driver ignores this.
Does AR_INTR_SYNC_HOST1_PER indicate a PICe parity error ?
We use Kernel 3.1.4.
Regards
Uwe Wojak
