Hello,
This patchset v4 resolves the tsan build failure seen in
https://gitlab.com/mstredhat/qemu/-/jobs/13201554945
Few variables were declared directly after a case label inside a switch,
causing the compilation failure.
These are now moved to the top of the block.
This series updates the existing PHB4 model to the latest spec:
"Power Systems Host Bridge 5 (PHB5) Functional Specification Version 0.5_00".
Updates include the following:
- implemented sticky reset logic
- implemented read-only, write-only, W1C and WxC logic
- return all 1's on read to unimplemented registers
- update PCIE registers for link status, speed and width
- implement IODA PCT debug table without any functionality
- update LSI Source-ID register based on small/big PHB number of interrupts
Also, a new testbench for PHB4 model is added that does XSCOM read/writes
to various registers of interest and verifies the values.
Regards.
