Subject: [RFC PATCH 0/6] MIPS: Handle CPU IRQ in domain's way
Date: Thu, 26 Mar 2020 14:16:56 +0800 [thread overview]
Message-ID: <20200326061704.387483-1-jiaxun.yang@flygoat.com> (raw)
In [1], we discussed about why MIPS CPU IRQ doesn't fit simple IRQ domain.
I felt it's time to remove this barrier and "modernize" the whole flow.
This set is simply a proof of concept of removing the whole MIPS_CPU_IRQ_BASE
and use the irq_domain's way.
Currently only Loongson64 and ip22 are adapted for testing purpose,
if everybody is happy with it, then I'll take a look at more platforms.
Btw: Thomas, are you still willing to drop some platforms in 5.8?
