Qualcomm Upstream Status BoF
summary
Status update on upstreaming Snapdragon kernel work lists concrete progress and blockers: qmi MTF merged, pH regulators posted, SMMU runtime-PM and context-bank work ongoing for SDM845/820, and the display driver is posted as an RFC. IPA driver is being refactored from ~38k to ~24k LOC toward a v1 upstream submission. Camera CSI for 8996 is merged in 4.14, audio HDAES basic playback/record is working, UFS core shows ~50% lane clock failure on some boards, and firmware DMA/physical memory mapping remains an unresolved hazard.
