Subject: [PATCH AUTOSEL 5.4 13/50] perf/smmuv3: Use platform_get_irq_optional() for wired interrupt
Date: Sat, 22 Feb 2020 21:21:58 -0500 [thread overview]
Message-ID: <20200223022235.1404-13-sashal@kernel.org> (raw)
In-Reply-To: <20200223022235.1404-1-sashal@kernel.org>
From: John Garry <john.garry@huawei.com>
[ Upstream commit 0ca2c0319a7bce0e152b51b866979d62dc261e48 ]
Even though a SMMUv3 PMCG implementation may use an MSI as the form of
interrupt source, the kernel would still complain that it does not find
the wired (GSIV) interrupt in this case:
root@(none)$ dmesg | grep arm-smmu-v3-pmcg | grep "not found"
[ 59.237219] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.8.auto: IRQ index 0 not found
[ 59.322841] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.9.auto: IRQ index 0 not found
[ 59.422155] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.10.auto: IRQ index 0 not found
[ 59.539014] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.11.auto: IRQ index 0 not found
[ 59.640329] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.12.auto: IRQ index 0 not found
[ 59.743112] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.13.auto: IRQ index 0 not found
[ 59.880577] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.14.auto: IRQ index 0 not found
[ 60.017528] arm-smmu-v3-pmcg arm-smmu-v3-pmcg.15.auto: IRQ index 0 not found
Use platform_get_irq_optional() to silence the warning.
If neither interrupt source is found, then the driver will still warn that
IRQ setup errored and the probe will fail.
