2026-04-28net: dummy: do not acquire RTNL for too longEric Dumazet
Instead of holding RTNL for an arbitrary amount of time, call register_netdev() for each dummy device created at module loading time. Tested: modprobe dummy numdummies=10000 Signed-off-by: Eric Dumazet <edumazet@google.com> Link: https://patch.msgid.link/20260427091016.737015-1-edumazet@google.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2026-04-29gpu: nova-core: enable GA100Timur Tabi
GA100 is a compute-only variant of GA102 that boots GSP-RM like a Turing, although it also has its own unique requirements. Now that all the pieces are in place, we can enable GA100 support. Although architecturally like an Ampere, GA100 uses the same GSP-RM firmware files as Turing, and therefore must boot it like Turing does. However, as a compute-only part, GA100 has no display engine.

2026-04-29gpu: nova-core: skip the IFR header if presentTimur Tabi
The GPU's ROM may begin with an Init-from-ROM (IFR) header that precedes the PCI Expansion ROM images (VBIOS). When present, the PROM shadow method must parse this header to determine the offset where the PCI ROM images actually begin, and adjust all subsequent reads accordingly. On most GPUs this is not needed because the IFR microcode has already applied the ROM offset so that PROM reads transparently skip the header. On GA100, for whatever reason, the IFR offset is not applied to PROM reads. Therefore, the search for the PCI expansion must skip the IFR header, if found.

2026-04-29gpu: nova-core: add FbHal::frts_size() for GA100 supportTimur Tabi
Introduce FbHal method frts_size() to return the size of the FRTS window. GA100 is a special case in that although there is an FRTS, its size must arbitrarily be set to 0. Note that we cannot use supports_display() to determine the FRTS size because there are other GPUs (e.g. GA102GL) that have display disabled (and so supports_display() returns False), but the FRTS window size still needs to be 1MB.

Nvidia GPUs have some PCI expansion ROM sections that have an Nvidia- specific signature instead of 0xAA55.

With the SizeConstants trait in scope, u64::SZ_1M replaces usize_as_u64(SZ_1M) and similar.

2026-04-28drm/xe: Don't use UTS_RELEASE directlyUwe Kleine-König (The Capable Hub)
UTS_RELEASE evaluates to a static string and changes quite easily (e.g. uncommitted changes in the source tree or new commits). So when checking if a patch introduces changes to the resulting binary each usage of UTS_RELEASE is source of annoyance. Instead of using UTS_RELEASE directly use init_utsname()->release which evaluates to the same string but with that a change of UTS_RELEASE doesn't affect xe_devcoredump.o.

2026-04-28drm/amdgpu: Move VM PTE MTYPE override to per-PTE granularityPhilip Yang
Refactor the NUMA-aware MTYPE override for VM page table entries: Move the override_vm_pte_flags call from the centralized amdgpu_vm_pte_update_flags() into the individual CPU and SDMA update backends, enabling per-PTE MTYPE override including for scattered pages (pages_addr path). Move APU, IP version, and direct-mapped eligibility checks from runtime (gmc_v9_0_override_vm_pte_flags) to init time (gmc_v9_0_set_gmc_funcs), to avoid repeated runtime checks on every PTE update.
