Subject: [Qemu-devel] [PATCH v2 3/4] hw/intc/arm_gicv3: Fix ICC register tracepoints
Date: Wed, 12 Oct 2016 18:54:35 +0100 [thread overview]
Message-ID: <1476294876-12340-4-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1476294876-12340-1-git-send-email-peter.maydell@linaro.org>
Fix some problems with the tracepoints for ICC register reads
and writes:
* tracepoints for ICC_BPR<n>, ICC_AP<n>R<x>, ICC_IGRPEN<n>,
ICC_EIOR<n> were not printing the <n> that indicated whether
the access was to the group 0 or 1 register
* the ICC_IGREPEN1_EL3 read function was not actually calling
the associated tracepoint
* the ICC_BPR<n> write function was incorrectly calling the
tracepoint for ICC_PMR writes
