11 dayskernel: cons: Fix newline caused by excessive '\b'Ian Moffett
Before this commit, if you were to write out too many backspace characters, it would result in an integer underflow for the scr->curs_col and scr->ch_col state resulting in the console logic assuming the cursor has gone too far off the screen which would cause behavior similar to as if you wrote out a line-feed character.

12 dayskernel: devfs: Add callback to request block sizeIan Moffett
Add bsize() callback within the bdevsw structure. This returns the number of blocks a block device supports at maximum. This result is *not* in bytes. Signed-off-by: Ian Moffett <ian@osmora.org>

13 daysproject: Build Hyra with ./hyra-install.shIan Moffett
- Deprecate *direct* use of 'make' for building world - Add hyra-build.sh to replace direct use of 'make' - Remove make vars that will no longer be used - Update workflow script for GitHub mirror - Add install media detection define (_INSTALL_MEDIA) - Add install media detection logs - Update build instructions within README.md Signed-off-by: Ian Moffett <ian@osmora.org>
2025-05-22kernel: Optimize console & loggingQuinn Stephens
* Modified draw loops to use `fbdev_get_index()` less often. * Created `cons_fast_putch()`, then used it to implement `cons_putch()` and `cons_putstr()`. This way, when printing an entire string, the lock acquire/release and cursor hide/show will only happen once, instead of once per character. * Modified `syslog_write()` to use `cons_putstr()`.

2025-05-22kernel: ahci: Create a DCDR per HBA deviceIan Moffett
Optimize reading of logical blocks within SATA drives by giving each device descriptor a drive cache descriptor ring. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-05-22kernel: dcdr: Overwrite existing DCDs if requiredIan Moffett
When writing to a drive, existing cached entries must be written through so DCD reads don't give stale data. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-05-22kernel/amd64: Improve GDT implementationQuinn Stephens
* Switched to using macros for the GDT entry bits, to improve clarity and make the code easier to modify. Also got rid of some junk values in a few of the entries. * Shrunk the GDT data array from 256 entries to 7 (GDT_ENTRY_COUNT) since the GDT will only ever use 7 of the entries for now. * Aligned the GDT using __cacheline_aligned, because the GDT entries will be read every time a segment selector is loaded. * Modified code dealing with the GDTR to just use `g_gdtr`, since the same GDT/GDTR is always used. * In `gdt_load()`, changed `eax` -> `ax`, since segment registers are only 16 bits. Also replaced the `gdtr` to just use `g_gdtr`. Additionally, used the inline assembly formatting to supply segment selectors with KERNEL_CS/DS macros.
