efi/runtime-wrappers: Remove duplicated macro for service returning void

2023-08-22T08:39:26+00:00

__efi_call_virt() exists as an alternative for efi_call_virt() for the sole reason that ResetSystem() returns void, and so we cannot use a call to it in the RHS of an assignment. Given that there is only a single user, let's drop the macro, and expand it into the caller. That way, the remaining macro can be tightened somewhat in terms of type safety too. Note that the use of typeof() on the runtime service invocation does not result in an actual call being made, but it does require a few pointer types to be fixed up and converted into the proper function pointer prototypes.

x86/platform/uv: UV support for sub-NUMA clustering

2023-05-31T16:34:59+00:00

Sub-NUMA clustering (SNC) invalidates previous assumptions of a 1:1 relationship between blades, sockets, and nodes. Fix these assumptions and build tables correctly when SNC is enabled.

x86/platform/uv: Introduce helper function uv_pnode_to_socket.

Add and use uv_pnode_to_socket() function, which parallels other helper functions in here, and will enable avoiding duplicate code in an upcoming patch. Signed-off-by: Steve Wahl Signed-off-by: Dave Hansen Link: https://lore.kernel.org/all/20230519190752.3297140-3-steve.wahl%40hpe.com

x86/platform/uv: Add platform resolving #defines for misc GAM_MMIOH_REDIRECT*

2023-05-31T16:34:59+00:00

Upcoming changes will require use of new #defines UVH_RH_GAM_MMIOH_REDIRECT_CONFIG0_NASID_MASK and UVH_RH_GAM_MMIOH_REDIRECT_CONFIG1_NASID_MASK, which provide the appropriate values on different uv platforms. Also, fix typo that defined a couple of "*_CONFIG0_*" values twice where "*_CONFIG1_*" was intended.

x86/platform/uv: Drop last traces of uv_flush_tlb_others

2020-11-11T12:16:51+00:00

Commit 39297dde7390 ("x86/platform/uv: Remove UV BAU TLB Shootdown Handler") removed uv_flush_tlb_others. Its declaration was removed also from asm/uv/uv.h. But only for the CONFIG_X86_UV=y case. The inline definition (!X86_UV case) is still in place. So remove this implementation with everything what was added to support uv_flush_tlb_others: * include of asm/tlbflush.h * forward declarations of struct cpumask, mm_struct, and flush_tlb_info Signed-off-by: Jiri Slaby Signed-off-by: Thomas Gleixner Acked-by: Mike Travis Acked-by: Steve Wahl Link: https://lore.kernel.org/r/20201109093653.2042-1-jslaby@suse.cz
