25 hoursproject: 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>
3 dayskernel: 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()`.

3 dayskernel: 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>
3 dayskernel: 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>
3 dayskernel/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.

10 dayskernel: proc: Do not introduce fork()Ian Moffett
Simplicity is divine, fork() may be powerful but is no longer simple. It became a thing in the late 70s during the early days of UNIX when computing was simple, when CPUs were only 16-bits, MMUs were not prevalent and RAM was only 512 KB. However it isn't 1971 anymore, process management, CPUs and memory architecture has advanced significantly since. This commit ceases work on the fork() syscall as implementing it would only introduce unnecessary complexity, security issues, hefty processing overhead and would perpetuate what should now be considered legacy. The current best alternative would be providing a form of process spawning as well as a mechanism to wait for the child process to complete. Signed-off-by: Ian Moffett <ian@osmora.org>
