This series performs some light refactoring required to be able to initialize members of the `Gpu` struct from GSP commands, and makes use of that refactoring to obtain and store the amount of VRAM on the device.
This is useful as probe-time information to be displayed, but will also become a parameter that can be queried from user-space once the nova-drm to nova-core bridge is established. This revision is just a rebase on top of the latest `drm-rust-next`, as the newly pushed patches introduced some non-trivial conflicts. Signed-off-by: Alexandre Courbot <[email protected]> --- Changes in v3: - Rebase against latest `drm-rust-next`. - Link to v2: https://patch.msgid.link/[email protected] Changes in v2: - Move `sysmem_flush` after `gsp_resources` to avoid use-after-drop. (Eliot and Sashiko) - Rename `usable_fb_regions_iter` to `usable_fb_regions`. - Return all usable regions as a `KVec`. - Let the caller compute the usable VRAM size instead of storing it as a `GetGspStaticInfoReply` property. - Dropped `Reviewed-by` tags on patch 3 as code has changed considerably. - Link to v1: https://patch.msgid.link/[email protected] To: Danilo Krummrich <[email protected]> To: Alice Ryhl <[email protected]> To: Alexandre Courbot <[email protected]> To: David Airlie <[email protected]> To: Simona Vetter <[email protected]> To: Benno Lossin <[email protected]> To: Gary Guo <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] --- Alexandre Courbot (2): gpu: nova-core: move GSP unload state to a pinned Gpu subobject gpu: nova-core: move GPU static information acquisition to a GSP method Joel Fernandes (1): gpu: nova-core: gsp: Extract and display usable FB regions from GSP drivers/gpu/nova-core/gpu.rs | 136 +++++++++++++++++++++---------- drivers/gpu/nova-core/gsp.rs | 14 +++- drivers/gpu/nova-core/gsp/boot.rs | 7 -- drivers/gpu/nova-core/gsp/commands.rs | 13 ++- drivers/gpu/nova-core/gsp/fw/commands.rs | 40 ++++++++- 5 files changed, 151 insertions(+), 59 deletions(-) --- base-commit: e655873885063245fd7f49f81cebfdfdef66a59d change-id: 20260609-boot-vram-00d5057102d5 Best regards, -- Alexandre Courbot <[email protected]>
