2025-02-19kernel/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.

2025-02-15project: Hyra Release v1.3Ian Moffett
What's new? - Add new defines in sys/cdefs.h. - Clean up Kernel synchronization API (sys/kern/kern_synch.c). - Added queue(3) and tree(3) to the man page directory. - Added extra security measures around interrupt entry code to prevent potentially nasty speculative execution issues (see commit 817d1ad). - Default to Clang/LLVM during builds. - Significant console optimizations (see commit d8fd1be) - Significant boot latency reductions due to PCI bus scan optimizations (see commit e7cf7a9) Signed-off-by: Ian Moffett <ian@osmora.org>

2025-02-15kernel: amd64: Add more defines to UART driverQuinn Stephens
Added more defines and comments to the UART driver, based on the 16550 chip datasheet, to make it more clear how each operation works. Signed-off-by: Quinn Stephens <quinn@osmora.org> Signed-off-by: Ian Moffett <ian@osmora.org>
2025-02-15kernel: pci: Optimize PCI bus scanningQuinn Stephens
Uses recursive bus/bridge scanning, skips nonexistent devices, and only scans for multiple functions on multifunction devices. This may result in PCI scanning being up to 100x as fast. Signed-off-by: Quinn Stephens <quinn@osmora.org> Signed-off-by: Ian Moffett <ian@osmora.org>
2025-02-15kernel: cons: Optimize console drawingQuinn Stephens
Prevents the cursor from being cleared right before a character is drawn or right after the screen is cleared. Also optimized the cursor drawing routine to just draw a rectangle instead of rendering a space character. Additionally renamed `cons_render_char()` to `cons_draw_char()` and fixed all characters being drawn one pixel too far to the right.
