9 dayskernel: 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>
9 dayskernel: 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>
9 dayskernel: 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.

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>

2024-12-15kernel: vm: Add objects, page struct and pagersIan Moffett
This commit expands the virtual memory subsystem by providing the initial implementation of virtual memory objects, pager descriptors and pagers. This change currently implemenents a minimal vnode pager. Signed-off-by: Ian Moffett <ian@osmora.org>

2024-12-07kernel: vcache: Add impl of "local" vcachesIan Moffett
This commit implements local vcaches and lazy vcache migration (LZVM) for on the fly vcache type switching. Signed-off-by: Ian Moffett <ian@osmora.org>
2024-12-07kernel: vcache: Improve vcache add/pull interfaceIan Moffett
Require internal add/pull routines to be passed a pointer to the vcache to be operated on. This makes it easier to support for per-process vcaches and LZVM. Signed-off-by: Ian Moffett <ian@osmora.org>
2024-11-13kernel: vfs: Recycle vnodes before allocatingIan Moffett
This commit makes changes to how vnodes are allocated and released. When we want to allocate a new vnode, we check if there is something we can recycle before calling dynalloc(). Instead of calling dynfree() on a vnode, enter it into the vnode cache. Signed-off-by: Ian Moffett <ian@osmora.org>

2024-11-04kernel: descrip: Add support for fd duplicationIan Moffett
Sometimes we may need to duplicate a file descriptor and create a new fdno that refers to the same vnode. The fd_dup() function enables us to do this when needed. Signed-off-by: Ian Moffett <ian@osmora.org>
