[PATCH 0/4] hw: acpi: support SPCR rev. 3 & UART clock freq in ARM SPCR

Posted by Vadim Chichikalyuk 3 months, 4 weeks ago

This series fixes erroneous building of ACPI SPCR tables in hw/acpi/aml-build.c, 
where the UART clock frequency field is omitted in revision 3 tables despite
being present since revision 3 of the specification.

The last three patches update the SPCR table for the AArch64 virt machine to
revision 3, exposing the UART clock frequency, which was not previously available
via ACPI, to the guest.

Thanks,
Vadim
