Subject: [PATCH 0/3] Save/restore for GICv3
Date: Tue, 14 Feb 2023 15:34:23 -0800	[thread overview]
Message-ID: <20230214233426.2994501-1-f.fainelli@gmail.com> (raw)

Hi all,

This patch series adds support for saving and restoring the GIC
distributor and re-distributor which was missing for platforms that
implement suspend states where the GIC loses power and therefore its
state.

The system that I have been testing this with has:

[    0.000000] GICv3: GIC: Using split EOI/Deactivate mode
[    0.000000] GICv3: 288 SPIs implemented
[    0.000000] GICv3: 0 Extended SPIs implemented
[    0.000000] Root IRQ handler: gic_handle_irq
[    0.000000] GICv3: GICv3 features: 16 PPIs

So no support for extended PPIs or SPIs, hopefully the code is correct,
or close to.

Thanks!
