[PATCH v2 2/2] LoongArch: KVM: Add interrupt checking with Loongson AVEC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is newly added macro INT_AVEC with CSR ESTAT register, which is
bit 14 used for Loongson AVEC support. AVEC interrupt status bit 14 is
supported with macro CSR_ESTAT_IS, here replace hardcoded value 0x1fff
with macro CSR_ESTAT_IS so that AVEC interrupt status is supported by
KVM also.
