Subject: [PATCH v3 0/3] Add smp booting support for Qualcomm ARMv8 SoCs
Date: Tue, 14 Apr 2015 14:58:37 -0500 [thread overview]
Message-ID: <1429041520-6720-1-git-send-email-galak@codeaurora.org> (raw)
This patch set adds support for SMP boot on the MSM8x16 family of Qualcomm SoCs.
To support SMP on the MSM8x16 SoCs we need to add ARMv8/64-bit SCM interfaces to
setup the boot/release addresses for the secondary CPUs. In addition we need
a uniquie set of cpu ops. I'm aware the desired methods for booting secondary
CPUs is either via spintable or PSCI. However, these SoCs are shipping with a
firmware that does not support those methods.
TODO:
* clean up docs related to 'qcom,arm-cortex-acc' and L2
v3:
* dropped use of pen, just release CPUs directly into secondary_start
v2:
* Dropped introduction and use of CPU_METHOD_OF_DECLARE
* Moved qcom cpu ops from drivers/soc/qcom to arch/arm64/kernel
* Renamed msm to qcom in cpu ops code, minor cleans (remove dead defines/code)
