Subject: Re: [PATCH 0/3] PCI: designware: Fixing MSI handling flow
Date: Fri, 7 Dec 2018 16:16:17 +0000	[thread overview]
Message-ID: <f991976a-dcc1-b23e-9a78-e82a622e207e@synopsys.com> (raw)
In-Reply-To: <86d0qrrmbc.wl-marc.zyngier@arm.com>

Hi all,

(snip)

I was able to reproduce Trent's problem in my configuration while developing the
eDMA driver, always having lost the second interrupt when an interrupt burst
occurs (observed in 50 trials).

After applying Marc's patch series, I stopped losing the second interrupt when
an interrupt burst occurs (I ran about 50 trials).

I can say with greater certainty that this fix solves the reported problem.

Regards,
Gustavo
