Subject: Re: [PATCH 0/3] irqchip/gic-v3: Lifetime and range fixes in the GICv3 and ITS drivers
Date: Thu, 8 Oct 2026 08:06:03 +0000 [thread overview]
Message-ID: <20261008080603.1987-1-ygjiugui@gmail.com> (raw)
In-Reply-To: <CA+EHjTx-MGu=Rh90WDnTWMS4=8vcOdbhR35g42BtRBy7wqXBXg@mail.gmail.com>
Hi,
Reproduced on /dev/hmv (HarmonyOS KVM). It advertises GITS_TYPER=0x803ff71 (IDBITS=0x1f), which triggers the unsigned-int truncation and causes nvecs to become 0.
Tested-by: yang <ygjiugui@gmail.com>
