stand: Recognize SHT_INIT_ARRAY sections as constructor sections

2026-07-15T14:58:32Z

Pass such a section to the kernel using modinfo, otherwise link_elf.c won't execute constructors for the file. This is required for KASAN, otherwise redzones for global buffers are not poisoned during boot.

stand: Fix shadow buffer offset handling

2026-06-30T19:52:55Z

The shadow buffer is addressed relative to `tg_origin`, which includes the padding offset, whereas `gfxfb_blt` operates on coordinates without that offset. To make `gfx_fb_copy_area` emulate the behavior of `gfxfb_blt`, the source coordinates must include the padding offset, while the destination coordinates must not. The original implementation omitted the offset from the source coordinates; this change corrects that. Additionally, `gfx_fb_cons_display` already applies the padding offset, so the redundant adjustment is removed.

stand: Bulk operations on each gfxfb_blt if shadow buffer enabled

2026-06-18T20:43:24Z

Previously, gfxfb_blt flushed the framebuffer on every call. Since a single drawing operation may invoke gfxfb_blt multiple times, this can result in unnecessary flushes. Instead, write updates to the shadow buffer (when present) and mark the affected area as dirty. Flushing is deferred so multiple gfxfb_blt calls can be coalesced into a single update. As before, only the dirty region is flushed. This fixes the slow bootloader problem in some platforms.

stand/common/load_elf: Do kernel module relocations for PPC

2026-04-18T12:07:10Z

reloc_ptr() skips relocations for the kernel module, because on most platforms the kernel is ET_EXEC and this is not required. On PPC, the kernel is ET_DYN and we need to relocate here, otherwise the module metadata will not be loaded properly and the kernel module will have an incorrect version, preventing module dependencies from resolving. This fixes loading kernel modules from loader.conf on powerpc.

Pass severity to vectx_open() rather than vectx_close()

2026-04-10T17:46:54Z

file_loadraw() can have a need to load unverified files like "dtrace_dof". Allow severity_guess() to look at the filename but if it returns less than VE_MUST check that the type is not one we insist on verifying. In vectx_open if severity < VE_MUST we can allow it to be unverified. If passed VE_GUESS we call severity_guess(). Regardless, we record severity in ctx so it is available to vectx_close().

loader.efi: only use firmware provided Blt on GOP

2026-01-04T13:15:37Z

gfx_state.tg_private points to a EFI_GRAPHICS_OUTPUT_PROTOCOL only when using GOP. The firmware provided Blt functions on UGA platforms have been observed to not work on old MacBooks, and are likley hit or miss anyways as UGA has been deprecated since 2006.

stand: Cut over to using the EDK2 files

2025-11-16T18:29:03Z

Remove the old EFI SDK files that we've been nursing along for too many years. Replace them with files from EDK2 edk2-stable202502 and tweak the interfaces we need to tweak. Mostly include different things or change the names of the protocols that no longer have old-school compat names. I gave up in the middle of env.c, too damn tedious to find all those new GUIDs. Also, many of the guids were mystery meat, most likely from the EDK2 sources, but just not the Include subdirectory. Need to investigate those. And the memory info? Is it just an oboslete thing, or embedded knowledge of EDK2. Delete the now-redundant copies of things in Guid and Protocol. I debated keeping ZeroGuid.h, but EDK2 has moved on from when I snagged it years ago (or maybe I just invented it out of whole cloth: edk2 does radically different things today and I didn't do the git deep-dive to find out).
