Hello, Here is a series of fixes and extensions provided by Ben which modify the POWER9 interrupt model to prepare ground for the support of the XIVE interrupt controller as found on POWER9 PowerNV machines.
Thanks C. Changes since initial patchset : - modified the commit log to comment the use of EXCP_HLT instead of POWERPC_EXCP_STOP - modified the icp_realize() and xive_tctx_realize() to take into account explicitely the POWER9 interrupt model - introduced a specific power9_set_irq for POWER9 Benjamin Herrenschmidt (10): target/ppc: Fix nip on power management instructions target/ppc: Don't clobber MSR:EE on PM instructions target/ppc: Fix support for "STOP light" states on POWER9 target/ppc: Move "wakeup reset" code to a separate function target/ppc: Rename "in_pm_state" to "resume_as_sreset" target/ppc: Add POWER9 exception model target/ppc: Detect erroneous condition in interrupt delivery target/ppc: Add Hypervisor Virtualization Interrupt on POWER9 target/ppc: Add POWER9 external interrupt model target/ppc: Add support for LPCR:HEIC on POWER9 include/hw/ppc/ppc.h | 2 + target/ppc/cpu-qom.h | 5 + target/ppc/cpu.h | 26 ++++- hw/intc/xics.c | 3 + hw/intc/xive.c | 3 + hw/ppc/ppc.c | 44 ++++++++- target/ppc/excp_helper.c | 164 +++++++++++++++++++++----------- target/ppc/translate.c | 28 ++++-- target/ppc/translate_init.inc.c | 34 ++++++- 9 files changed, 238 insertions(+), 71 deletions(-) -- 2.20.1
