Upstream group support is not in a complete or usable state as it is. * Significant context push/pull improvements, particularly pool and phys context handling was quite incomplete beyond trivial OPAL case that pushes at boot. * Improved tracing and checking for unimp and guest error situations. * Various other missing feature support. ---------------------------------------------------------------- Glenn Miles (12): ppc/xive2: Fix calculation of END queue sizes ppc/xive2: Use fair irq target search algorithm ppc/xive2: Fix irq preempted by lower priority group irq ppc/xive2: Fix treatment of PIPR in CPPR update pnv/xive2: Support ESB Escalation ppc/xive2: add interrupt priority configuration flags ppc/xive2: Support redistribution of group interrupts ppc/xive: Add more interrupt notification tracing ppc/xive2: Improve pool regs variable name ppc/xive2: Implement "Ack OS IRQ to even report line" TIMA op ppc/xive2: Redistribute group interrupt precluded by CPPR update ppc/xive2: redistribute irqs for pool and phys ctx pull Michael Kowal (4): ppc/xive2: Remote VSDs need to match on forwarding address ppc/xive2: Reset Generation Flipped bit on END Cache Watch pnv/xive2: Print value in invalid register write logging pnv/xive2: Permit valid writes to VC/PC Flush Control registers Nicholas Piggin (34): ppc/xive: Fix xive trace event output ppc/xive: Report access size in XIVE TM operation error logs ppc/xive2: fix context push calculation of IPB priority ppc/xive: Fix PHYS NSR ring matching ppc/xive2: Do not present group interrupt on OS-push if precluded by CPPR ppc/xive2: Set CPPR delivery should account for group priority ppc/xive: tctx_notify should clear the precluded interrupt ppc/xive: Explicitly zero NSR after accepting ppc/xive: Move NSR decoding into helper functions ppc/xive: Fix pulling pool and phys contexts pnv/xive2: VC_ENDC_WATCH_SPEC regs should read back WATCH_FULL ppc/xive: Change presenter .match_nvt to match not present ppc/xive2: Redistribute group interrupt preempted by higher priority interrupt ppc/xive: Add xive_tctx_pipr_present() to present new interrupt ppc/xive: Fix high prio group interrupt being preempted by low prio VP ppc/xive: Split xive recompute from IPB function ppc/xive: tctx signaling registers rework ppc/xive: tctx_accept only lower irq line if an interrupt was presented ppc/xive: Add xive_tctx_pipr_set() helper function ppc/xive2: split tctx presentation processing from set CPPR ppc/xive2: Consolidate presentation processing in context push ppc/xive2: Avoid needless interrupt re-check on CPPR set ppc/xive: Assert group interrupts were redistributed ppc/xive2: implement NVP context save restore for POOL ring ppc/xive2: Prevent pulling of pool context losing phys interrupt ppc/xive: Redistribute phys after pulling of pool context ppc/xive: Check TIMA operations validity ppc/xive2: Implement pool context push TIMA op ppc/xive2: redistribute group interrupts on context push ppc/xive2: Implement set_os_pending TIMA op ppc/xive2: Implement POOL LGS push TIMA op ppc/xive2: Implement PHYS ring VP push TIMA op ppc/xive: Split need_resend into restore_nvp ppc/xive2: Enable lower level contexts on VP push hw/intc/pnv_xive2_regs.h | 1 + include/hw/ppc/xive.h | 66 +++- include/hw/ppc/xive2.h | 22 +- include/hw/ppc/xive2_regs.h | 22 +- hw/intc/pnv_xive.c | 16 +- hw/intc/pnv_xive2.c | 140 ++++++--- hw/intc/spapr_xive.c | 18 +- hw/intc/xive.c | 555 ++++++++++++++++++++++------------ hw/intc/xive2.c | 717 +++++++++++++++++++++++++++++++++----------- hw/ppc/pnv.c | 48 +-- hw/ppc/spapr.c | 21 +- hw/intc/trace-events | 12 +- 12 files changed, 1146 insertions(+), 492 deletions(-)
