gpu: nova-core: remove `io::` qualifier to register macro invocations

2026-03-26T06:10:29+00:00

The kernel's `register` macro would clash with nova-core's own version if it was imported directly, so it was accessed through its `io` module during the conversion phase. Now that nova-core's `register` macro doesn't exist anymore, we can import and use it directly without risk of name collision.

gpu: nova-core: convert falcon registers to kernel register macro

2026-03-26T06:09:44+00:00

Convert all PFALCON, PFALCON2 and PRISCV registers to use the kernel's register macro and update the code accordingly. Because they rely on the same types to implement relative registers, they need to be updated in lockstep. nova-core's local register macro is now unused, so remove it.

Convert all PFB registers to use the kernel's register macro and update the code accordingly. NV_PGSP_QUEUE_HEAD was somehow caught in the PFB section, so move it to its own section and convert it as well.
