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>
