soc/intel/cmn: Clear interrupt status after HECI-1 has been received
According to Intel doc#630774, BIOS should clear Host Interrupt Status if it has read all the slots of the message from the ME circular buffer. Since this is not found in client ME document, add a Kconfig SOC_INTEL_CSE_SERVER_SKU that only clears interrupt status for Server ME SKU. On SPR-SP, if mainboard calls get_me_fw_version via HECI-1, with the change can avoid seeing below Linux warning during boot with Linux v5.12: [ 17.868929] irq 16: nobody cared (try booting with the "irqpoll" option) [ 17.883819] CPU: 10 PID: 0 Comm: swapper/10 Not tainted 5.12.0 [ 17.902412] Hardware name: Wiwynn Crater Lake EVT2/Crater Lake-Class1 [ 17.922327] Call Trace: [ 17.927780] <IRQ> [ 17.932253] dump_stack+0x64/0x7c [ 17.939640] __report_bad_irq+0x37/0xb1 [ 17.948206] note_interrupt.cold.11+0xa/0x63 [ 17.957713] handle_irq_event_percpu+0x6a/0x80 [ 17.967626] handle_irq_event+0x2a/0x50 [ 17.976163] handle_fasteoi_irq+0x9e/0x140 [ 17.985305] __common_interrupt+0x38/0x90 [ 17.994255] common_interrupt+0x7a/0xa0 [ 18.002821] </IRQ> [ 18.007514] asm_common_interrupt+0x1e/0x40 Change-Id: I1cf21112870e53a11134d43e461b735ead239717 Signed-off-by: Johnny Lin <johnny_lin@wiwynn.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/66579 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <inforichland@gmail.com>
