Subject: [PATCH v6 03/11] target/arm: Restrict ARMv4 cpus to TCG accel
Date: Sun, 31 Jan 2021 12:50:14 +0100 [thread overview]
Message-ID: <20210131115022.242570-4-f4bug@amsat.org> (raw)
In-Reply-To: <20210131115022.242570-1-f4bug@amsat.org>
KVM requires the target cpu to be at least ARMv8 architecture
(support on ARMv7 has been dropped in commit 82bf7ae84ce:
"target/arm: Remove KVM support for 32-bit Arm hosts").
Only enable the following ARMv4 CPUs when TCG is available:
- StrongARM (SA1100/1110)
- OMAP1510 (TI925T)
The following machines are no more built when TCG is disabled:
- cheetah Palm Tungsten|E aka. Cheetah PDA (OMAP310)
- sx1 Siemens SX1 (OMAP310) V2
- sx1-v1 Siemens SX1 (OMAP310) V1
