3 dayskernel/amd64: isa: Add initial i8237 driver implIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
4 dayskernel/amd64: bus: Add bus resource interfaceIan Moffett
This commit introduces a bus resource abstraction. A bus resource encapsulates bus specific information and semantics. Along with abstracting away bus specific details and providing an overall smoother interface, this additionally provides flexibility, access control and security by keeping track of permissions and allowing things to be turned on or off.

2024-12-20kernel/amd64: proc: Protect SWAPGS with LFENCEIan Moffett
Ensure all loads preceding SWAPGS are serialized using LFENCE. This mitigates the possibility of SWAPGS being speculatively bypassed which would lead to security issues. Signed-off-by: Ian Moffett <ian@osmora.org>

Maintain naming consistency between public machine-dependent and machine-independent functions. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2024-07-29kernel/amd64: cpu: Write cpu_info to IA32_GS_BASEIan Moffett
Instead of writing cpu_info to IA32_KERNEL_GS_BASE then using SWAPGS, write the cpu_info pointer directly to IA32_GS_BASE Signed-off-by: Ian Moffett <ian@osmora.org>

2024-07-10kernel/amd64: reboot: Halt all with REBOOT_HALTIan Moffett

2024-07-02kernel/amd64: Handle the user GS segment registerIan Moffett
This commit introduces usage of swapgs to switch out the GS register with the user GS register. An md_td_kick() function is also introduced to start up user threads. The this_cpu() function uses the GS register to read the current CPU structure using a new "self" field. Signed-off-by: Ian Moffett <ian@osmora.org>
2024-07-02kernel/amd64: Add INTRENTRY() and TRAPENTRY()Ian Moffett
Add macros that perform certain operations before invoking the actual handler. This will be useful in the future for more complicated operations that need to be done before the handler is ran. Signed-off-by: Ian Moffett <ian@osmora.org>
