Hi Dave and Sima, Here goes our last drm-xe-next PR towards 6.17.
It brings a lot of workarounds infra and additions and the enabling of SRIOV capability in BMG, as long as underneath hardware SKU and Firmware supports it as well. Thanks, Rodrigo. drm-xe-next-2025-07-15: Driver Changes: - Create and use XE_DEVICE_WA infrastructure (Atwood) - SRIOV: Mark BMG as SR-IOV capable (Michal) - Dont skip TLB invalidations on VF (Tejas) - Fix migration copy direction in access_memory (Auld) - General code clean-up (Lucas, Brost, Dr. David, Xin) - More missing XeLP workarounds (Tvrtko) - SRIOV: Relax VF/PF version negotiation (Michal) - SRIOV: LMTT invalidation (Michal) The following changes since commit 94de94d24ea8cf567ec7254a723c3192c72c2ca6: drm/xe/guc: Cancel ongoing H2G requests when stopping CT (2025-07-10 21:46:29 +0200) are available in the Git repository at: https://gitlab.freedesktop.org/drm/xe/kernel.git tags/drm-xe-next-2025-07-15 for you to fetch changes up to a81648768178f6adf171d98db486b4b2613f645a: drm/xe/pf: Invalidate LMTT after completing changes (2025-07-15 13:05:22 +0200) ---------------------------------------------------------------- Driver Changes: -
