* stand: Bulk operations on each gfxfb_blt if shadow buffer enabledShengYi Hung2026-06-181-1/+2
| | | | | | | | | | | | | | | | | | | 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.

* loader: provide a features table for binary compatibility advertisementKyle Evans2023-12-081-0/+48
| | | | | | | | | | | | | | | | | | | | | | liblua now provides a loader.has_feature() function to probe the loader binary for features advertised. name => desc mappings are provided in loader.features to get a list of all of the features loader *can* support. core.hasFeature is provided as a shim to loader.has_feature so that individual consumers don't need to think about the logic of the loader module not providing has_feature; we know that means the feature isn't enabled. The first consumer of this will be EARLY_ACPI to advertise that the loader binary probes for ACPI presence before the interpreter has started, so that we know whether we can trust the presence of acpi.rsdp as relatively authoritative. In general, it's intended to be used to avoid breaking new scripts on older loaders within reason. This will be used in lua as `core.hasFeature("EARLY_ACPI")`, while the C bits of loader will `feature_enable(FEATURE_EARLY_ACPI)`.

In addition, it switches around how we flavor liblua for the boot loader and flua.

* veloader use vectx API for kernel and modulesSimon J. Gerraty2020-03-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vectx API, computes the hash for verifying a file as it is read. This avoids the overhead of reading files twice - once to verify, then again to load. For doing an install via loader, avoiding the need to rewind large files is critical. This API is only used for modules, kernel and mdimage as these are the biggest files read by the loader. The reduction in boot time depends on how expensive the I/O is on any given platform. On a fast VM we see 6% improvement. For install via loader the first file to be verified is likely to be the kernel, so some of the prep work (finding manifest etc) done by verify_file() needs to be factored so it can be reused for vectx_open(). For missing or unrecognized fingerprint entries, we fail in vectx_open() unless verifying is disabled. Otherwise fingerprint check happens in vectx_close() and since this API is only used for files which must be verified (VE_MUST) we panic if we get an incorrect hash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever extensions we need for base system operations. We currently support a subset of lfs and lposix that are used in the rewrite of makesyscall.sh into lua, added in r354786. flua is intentionally written such that one can install standard lua and some set of lua modules from ports and achieve the same effect. linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added in. This is similar to what we do in stand/. linit.c has been renamed to make it clear that this has flua-specific bits. luaconf has been slightly obfuscated to make extensions more difficult. Part of the problem is that flua is already hard enough to use as a bootstrap tool because it's not in PATH- attempting to do extension loading would require a special bootstrap version of flua with paths changed to protect the innocent. src.lua.mk has been added to make it easy for in-tree stuff to find flua, whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.

| | | | | | | | | | | | | | | | | | | | | | An integrity check such as a check-hash or a cross-correlation failed. The integrity error falls between EINVAL that identifies errors in parameters to a system call and EIO that identifies errors with the underlying storage media. EINTEGRITY is typically raised by intermediate kernel layers such as a filesystem or an in-kernel GEOM subsystem when they detect inconsistencies. Uses include allowing the mount(8) command to return a different exit value to automate the running of fsck(8) during a system boot. These changes make no use of the new error, they just add it.
