From ccc27d2ccad2e016262923ee241b1569a6085118 Mon Sep 17 00:00:00 2001 From: Dmitry Ponamorev Date: Wed, 15 Sep 2021 03:19:15 -0700 Subject: soc/intel/baytrail,denverton_ns: Call setup_lapic() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A custom board with soc/intel/denverton_ns does not respond to the keyboard and does not boot from the sata/USB disks. Last post code 0x7b and the last line that is displayed at log from SeaBIOS is: All threads complete. The issue is gone when adding setup_lapic() call to configure EXTINT delivery of i8259 originated interrupts for the LAPIC. Replicate call from other soc/ and make the call for both BSP and AP CPUs. Similar change was done for soc/intel/braswell in commit b4f57bb3cac3ab29b9fa9c526ad4358faffb77a1.
