[PATCH 0/8] clocksource/drivers/timer-goldfish: Fix bugs and add DT support

From: Kuan-Wei Chiu

Date: Thu Nov 05 2026 - 11:24:02 EST


The goldfish timer driver was previously only used and tested on
single core m68k virt, but the same device is also present on other
qemu virt machines such as riscv and or1k, where running on SMP exposes
several issues.

Fix the concurrency, oneshot, and registration bugs in the driver, add
device tree probing support so it can be used across these platforms,
and add a MAINTAINERS entry.

Tested on qemu m68k virt and on qemu riscv64 virt with 4 SMP cores. On
riscv64, testing was done by passing clocksource=goldfish_timer on the
kernel command line and locally bumping the clock_event_device rating
above the architected timer to verify both clocksource and oneshot
clockevent operation.
