2023-12-11kernel: init: Fixup call orderIan Moffett
Some virtual memory routines are called by processor_init()... This is a temporary workaround until these calls are moved to processor_init() Signed-off-by: Ian Moffett <ian@osmora.org>
2023-12-11kernel/amd64: Update arch(9)Ian Moffett
This commit cleans up arch(9) as a few things were noticed. First, it would make sense to identify cores (described by the cpu_info structure) in every arch ported, thus the lapic_id has been changed to id so it can be shared. Some annotations have also been added for the sake of clarity. The manpage for arch(9) has also been cleaned up. Signed-off-by: Ian Moffett <ian@osmora.org>

2023-11-12kernel/amd64: lapic: Remove ESR supportsigsegv7

Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-10-06kernel/docs: Add new conventionsigsegv7
This commit adds a new convention that requires devs to write a comment for headers that have a manpage tied to them that shows which manpage it is tied to. Signed-off-by: sigsegv7 <ian@vegaa.systems>

Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-10-04kernel/amd64: Initialize IDT and GDT firstsigsegv7
This commit moves the interrupts_init() and gdt_load() calls to the top so interrupts are set up first in case something goes wrong so we can get information from exception handlers. Signed-off-by: sigsegv7 <ian@vegaa.systems>

2023-10-04kernel/amd64: Add AMD64 CPU abstractionssigsegv7

2023-09-28kernel: cdefs: Wrap assembly within conditionalsigsegv7
This commit wraps __KERNEL_META for .S files within a conditional. Only makes it easier to trace if on a different architecture and it is not implemented for it; however, this macro could perhaps be placed in a better header (XXX)? This should work for now. Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-28kernel/amd64: Add __KERNEL_META for .S filessigsegv7
Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-28kernel: mmio: Add memory barriers to helperssigsegv7
This commit introduces memory barriers to MMIO read/write helpers to ensure the compiler does not re-order these critical memory accesses which would in turn result in very strange behaviour if it were to be re-ordered. Signed-off-by: sigsegv7 <ian@vegaa.systems>

2023-09-26kernel: Fix spinlock_acquire() flawsigsegv7
This commit fixes a spinlock_acquire() flaw and corrects a [quite an implausible] mistake, in which we do not even spin. It would have been fine how it was before in Vega's contemporary state; however, not a good idea to keep. Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-25kernel/amd64: Add spectre mitigation supportsigsegv7
Add spectre mitigation support for AMD64 hosts which may be enabled via the --enable-spectre-mitigation configure flag. This commit currently only adds IBRS support but more techniques may be added later on. Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-25kernel: cdefs: Add __naked macrosigsegv7
Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-21kernel: cdefs: Add __STATIC_ASSERT macrosigsegv7
This commit adds a __STATIC_ASSERT which wraps over _Static_assert() to be more consistent with Vega style. Signed-off-by: sigsegv7 <ian@vegaa.systems>

2023-09-20kernel: dev: Use errno.h error codessigsegv7
This commit makes the hpet_sleep() function return either EXIT_SUCCESS or EXIT_FAILURE instead of hardcoded constants. Signed-off-by: sigsegv7 <ian@vegaa.systems>

Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-20kernel: Update timer routine return typessigsegv7
This commit makes msleep(), usleep(), etc, return an error code of either EXIT_SUCCESS or EXIT_FAILURE for error handling. This commit also makes the calibrate() routine return a frequency (ideally in Hz), however, it is optional and can return 0 as a way of saying it doesn't return one. Signed-off-by: sigsegv7 <ian@vegaa.systems>
2023-09-20kernel: Add timer abstractionsigsegv7
This commit introduces a new timer abstraction that is architecture-independent. It enables the registration and request of timers in a consistent and uniform manner abstracting away architectural details. Signed-off-by: sigsegv7 <ian@vegaa.systems>
