[PATCH v5 00/10] PMU-EBB support for PPC64 TCG

[Daniel Henrique Barboza]

Hi,

In this new version the concept of PMUEvent was removed. We're now
using only the PMUEventType enum and retrieving it on demand via a
new helper called getPMUEventType. This also means that we're not
trapping MMCR1 writes.

Changes from v4:
- patches 1-4 from v4: already upstream
- former patch 6 (initialize PMUEvents on MMCR1 write): removed
- patch 1 (former 6):
  * removed PMUEvent type
  * overflow timers are back to CPUPPCState
- patch 2 (former 7):
  * added a new getPMUEventType() function
- other patches were changed to accomodate the changes in patch 1 and 2
- v4 link: https://lists.gnu.org/archive/html/qemu-devel/2021-10/msg03710.html
