[PATCH AUTOSEL 5.10 4/5] kselftest/arm64: Corrupt P0 in the irritator when testing SSVE

by Sasha Levin

From: Mark Brown <broonie(a)kernel.org> [ Upstream commit 3e360ef0c0a1fb6ce9a302e40b8057c41ba8a9d2 ] When building for streaming SVE the irritator for SVE skips updates of both P0 and FFR. While FFR is skipped since it might not be present there is no reason to skip corrupting P0 so switch to an instruction valid in streaming mode and move the ifdef.

[PATCH] selftest: drivers: Add support to check duplicate hwirq

by Joseph Jang

Validate there are no duplicate hwirq from the irq debug file system /sys/kernel/debug/irq/irqs/* per chip name. One example log show 2 duplicated hwirq in the irq debug file system. $ sudo cat /sys/kernel/debug/irq/irqs/163 handler: handle_fasteoi_irq device: 0019:00:00.0 <SNIP> node: 1 affinity: 72-143 effectiv: 76 domain: irqchip@0x0000100022040000-3 hwirq: 0xc8000000 chip: ITS-MSI flags: 0x20 $ sudo cat /sys/kernel/debug/irq/irqs/174 handler: handle_fasteoi_irq device: 0039:00:00.0 <SNIP> node: 3 affinity: 216-287 effectiv: 221 domain: irqchip@0x0000300022040000-3 hwirq: 0xc8000000 chip: ITS-MSI flags: 0x20 The irq-check.sh can help to collect hwirq and chip name from /sys/kernel/debug/irq/irqs/* and print error log when find duplicate hwirq per chip name. Kernel patch ("PCI/MSI: Fix MSI hwirq truncation") [1] fix above issue.
