Subject: [PULL 33/40] docs/system: riscv: Document AIA options for virt machine
Date: Sat, 12 Feb 2022 10:00:24 +1000	[thread overview]
Message-ID: <20220212000031.3946524-34-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20220212000031.3946524-1-alistair.francis@opensource.wdc.com>

From: Anup Patel <anup.patel@wdc.com>

We have two new machine options "aia" and "aia-guests" available
for the RISC-V virt machine so let's document these options.

   When this option is "on", ACLINT devices will be emulated instead of
   SiFive CLINT. When not specified, this option is assumed to be "off".
 
+- aia=[none|aplic|aplic-imsic]
+
+  This option allows selecting interrupt controller defined by the AIA
+  (advanced interrupt architecture) specification. The "aia=aplic" selects
+  APLIC (advanced platform level interrupt controller) to handle wired
+  interrupts whereas the "aia=aplic-imsic" selects APLIC and IMSIC (incoming

+  MSIs. When not specified, this option is assumed to be "none" which selects
+  SiFive PLIC to handle wired interrupts.

+- aia-guests=nnn
+
+  The number of per-HART VS-level AIA IMSIC pages to be emulated for a guest
+  having AIA IMSIC (i.e. "aia=aplic-imsic" selected). When not specified,
+  the default number of per-HART VS-level AIA IMSIC pages is 0.
