111e3475e3 Raise MEM_E820_ENTRIES_NUM to 256, remove memmap entry count max check in zealbooter at suggestion of mintsuki. 2022-09-12 04:26:10 -04:00

8297c769e6 Fix zealbooter memmap kernel header buffer-overflow. 
Previously the zealbooter memmap e820 assignment loop used the entry count value passed via limine, without checking if it was over MEM_E820_ENTRIES_NUM, the #define constant value limit of entries that are stored in the kernel header's e820 region. This commit bumps up the constant entry count to 64 from 48, and also adds a small check in zealbooter to ensure that the entry count value used in the memmap loop caps off at the constant value.

7d31064b6a Abstract out VBE vars from most of OS, revise dev uefi temp vm build system. 
Misc UEFI build scripts have been removed/revised/condensed into one script with multiple rebuild steps. The order of the steps is as follows: Auto-install into temp VM with custom AUTO-VM iso, merge kernel headers into VM, rebuild kernel, merge Kernel/ code, rebuild kernel, merge all src/ code, deploy limine and zealbooter, rebuild kernel (as well as test), then test UEFI and BIOS mode.
