[SRU Justification]
[ Impact ]
AMD Strix Halo devices experience unexpected reboots while starting
GUI session every boot.
This is caused by:
* 689275140cb8e drm/amdgpu/hdp7.0: do a posting read when flushing HDP
* abe1cbaec6cfe drm/amdgpu/hdp6.0: do a posting read when flushing HDP
* f756dbac1ce1d drm/amdgpu/hdp5.2: do a posting read when flushing HDP
* cf424020e040b drm/amdgpu/hdp5.0: do a posting read when flushing HDP
* c9b8dcabb52af drm/amdgpu/hdp4.0: do a posting read when flushing HDP
And fixed by:
* 5a11a27677311 drm/amdgpu/hdp7: use memcfg register to post the write for
HDP flush
* ca28e80abe421 drm/amdgpu/hdp6: use memcfg register to post the write for
HDP flush
* dbc988c689333 drm/amdgpu/hdp5.2: use memcfg register to post the write for
HDP flush
* 0e33e0f339b91 drm/amdgpu/hdp5: use memcfg register to post the write for
HDP flush
* f690e3974755a drm/amdgpu/hdp4: use memcfg register to post the write for
HDP flush
[ Test Plan ]
1. Install -proposed kernel
2. Reboot to the installed kernel and check if the device may finish boot
process to GUI session.
[ Where problems could occur ]
No. This fix a problem when reading back the whole mapped
KFD_MMIO_REMAP_HDP_MEM_FLUSH_CNTL register by reading another register
that also triggers the flush.
[ Other Info ]
The causing commits were first committed to v6.13-rc1 , and have also been
backported to v6.12.5, v6.6.69, v6.1.120. The fixes are available in v6.15-rc6,
also backported to v6.14.7, v6.12.29, v6.6.91, v6.1.139, therefore this affects
following Ubuntu kernels:
* linux/plucky: all (currently 6.14.0-22.22)
* linux-oem-6.14/noble: all (currently 6.14.0-1005.5)
* linux/oracular: 6.11.0-20.20 to latest (currently 6.11.0-28.28)

* linux-oem-6.8/noble: 6.8.0-1026.26 to latest (currently 6.8.0-1029.29)
Nominate for linux/noble, linux-oem-6.8/noble, linux/oracular, linux-
oem-6.11/noble, linux/plucky, and linux-oem-6.14/noble.
========== original bug report ==========
With 5 v6.13-rc1 commits , also backported to v6.12.5, v6.6.69, v6.1.120,
