The applesmc device only answers APPLESMC_READ_CMD at its command port. Modern macOS guests (x86 10.14+, all 15.x) also issue WRITE, TYPE and GET_KEY_BY_INDEX, and enumerate the SMC key space at boot. The unanswered commands and the near-empty key table drive the AppleSMC kext into a kSMCSpuriousData retry storm (~1800 errors/sec, kernel_task ~70% CPU, WindowServer ~509% CPU on macOS 15).Patch 1 implements the missing commands. Patch 2 populates the key table with a realistic iMac20,1 profile and the canonical #KEY count, so the guest's boot-time enumeration terminates. v4: - Regenerated against current master. Drop a stray hunk in patch 2/2 that reverted the qdev-properties.h include move (commit 78d45220b4); the include is now left untouched. Reported-by Philippe Mathieu-Daudé. No functional change. - No other changes from v3. v3: https://lore.kernel.org/qemu-devel/[email protected]/ v2: addressed Peter Maydell's style review (loop braces, stl_be_p()). v1: https://lore.kernel.org/qemu-devel/[email protected]/ Matthew Jackson (2): hw/misc/applesmc: implement GET_KEY_BY_INDEX, WRITE and TYPE commands hw/misc/applesmc: populate Apple SMC key table hw/misc/applesmc.c | 344 ++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 337 insertions(+), 7 deletions(-)
Hi! This does not look like a series which is "trivial enough" for qemu-trivial tree :) Thanks, /mjt
