PAPR defines a feature negotiation protocol between host and guest called ibm,client-architecture-support or CAS. When invoked by the guest this can either result in updated device tree information being given to the guest to indicate the new configuration, or it can trigger a reboot (called a CAS reboot) for more wide reaching configuration changes.
CAS changes are time consuming and irritating for the user, so we'd like to avoid them as much as possible. We hope we can avoid them in all situations, in fact, but there's some work to do to get there. This series has some initial changes that get us closer to that mark. Alexey Kardashevskiy (4): spapr: Fixes a leak in CAS spapr: Skip leading zeroes from memory@ DT node names spapr: Do not put empty properties for -kernel/-initrd/-append spapr: Stop providing RTAS blob David Gibson (3): spapr: Simplify handling of pre ISA 3.0 guest workaround handling spapr: Move handling of special NVLink numa node from reset to init spapr: Perform machine reset in a more sensible order MAINTAINERS | 2 - Makefile | 2 +- configure | 6 +- hw/ppc/spapr.c | 128 ++++++++++++++------------------ hw/ppc/spapr_hcall.c | 3 +- hw/ppc/spapr_rtas.c | 41 ---------- include/hw/ppc/spapr.h | 4 +- pc-bios/spapr-rtas.bin | Bin 20 -> 0 bytes pc-bios/spapr-rtas/Makefile | 27 ------- pc-bios/spapr-rtas/spapr-rtas.S | 37 --------- 10 files changed, 58 insertions(+), 192 deletions(-) delete mode 100644 pc-bios/spapr-rtas.bin delete mode 100644 pc-bios/spapr-rtas/Makefile delete mode 100644 pc-bios/spapr-rtas/spapr-rtas.S -- 2.21.0
