Subject: [PATCH V2 2/5] MIPS: DTS: Fix number of msi vectors for Loongson64G
Date: Thu, 30 Jul 2020 16:51:27 +0800 [thread overview]
Message-ID: <1596099090-23516-3-git-send-email-chenhc@lemote.com> (raw)
In-Reply-To: <1596099090-23516-1-git-send-email-chenhc@lemote.com>
HT irqs vectors are 8 groups, each group has 32 irqs, Loongson64C CPUs
can use only 4 groups and Loongson64G CPUs can use all 8 groups. So the
number of msi vectors of Loongson64G is 192 (32*8 - 64 = 192).
Fixes: 24af105962c8004edb9f5bf84 ("MIPS: Loongson64: DeviceTree for LS7A PCH")
