coreboot has ACPI while 2 others don't. *BSD need ACPI and have trouble
without it. Don't even attempt to boot *BSD on multiboot or qemu targets.
On coreboot boot all *BSD except 32-bit NetBSD which apparently does some
early BIOS calls.
efiemu is supposed to be disabled when compiling through exe format.
Unfortunately format was determined only after efiemu check. Reorder to fix the
problem
On emu some checks can be laxer like check for relocation range. Additionally
module loading in emu is rarely used. So skip this check rather than making
it laxer for all platforms. In ideal we may want to have slightly different
check for emu but for now this is good enough.
This argument disables generation of calls to __chkstk_ms. Those calls are
useless on GRUB as function is dummy. Yet they increase module size and
use limited-range relocations which may not work under some memory layouts.
We currently don't use such layouts on concerned platforms but lt's correct
this.
This section is generated by clang and is useful only for debugging.
It contains exotic relocations, so strip them to avoid them interferring
with module loading.
Currently only Windows gets distinguished icons, everything else is displayed
using the same generic one. Add additional --class based on os-prober returned
label, which usually is expected to match primary distribution name.
Also use it for Windows as well - chainloader prober may actually return
different strings (Windows, MS-DOS, Windows9xME).
This was lost when code was refactored. Patch restores previous behavior.
It is still not clear whether this is the right one. Due to the way we
detect DM abstraction, partitions on DM are skipped, we fall through to
generic detection which ends up in assuming parent device is BIOS disk.
It is useful to install GRUB on VM disk from the host. But it also means
that GRUB will mistakenly allow install on real system as well.
For now let's fix regression; future behavior needs to be discussed.
Closes: 45163
GRUB keeps partition offset and size in units of 512B sectors. Media paths
are defined in terms of LBA which are presumed to match HDD sector size.
This is probably cosmetic (EFI requires that partition is searched by GUID)
and still incorrect if GPT was created using different logical block size.
But current code is obviously wrong and new has better chances to be correct.
Otherwise it causes subsequent file open to fail, because grub_file_open
misinterprets set grub_errno for grub_file_get_device_name failure.
Closes: 46540
Define
* GRUB_EFI_PERSISTENT_MEMORY (UEFI memory map type 14) per UEFI 2.5
* GRUB_MEMORY_PERSISTENT (E820 type 7) per ACPI 3.0
* GRUB_MEMORY_PERSISTENT_LEGACY (E820 unofficial type 12) per ACPI 3.0
and translate GRUB_EFI_PERSISTENT_MEMORY to GRUB_MEMORY_PERSISTENT in
grub_efi_mmap_iterate().
Includes
* adding the E820 names to lsmmap
* handling the E820 types in make_efi_memtype()

While adding tcp window scaling support I was finding that I'd get some packet
loss or reordering when transferring from large distances and grub would just
timeout. This is because we weren't ack'ing when we got our OOO packet, so the
sender didn't know it needed to retransmit anything, so eventually it would fill
the window and stop transmitting, and we'd time out. Fix this by ACK'ing when
we don't find our next sequence numbered packet. With this fix I no longer time
out. Thanks,

Condition was accidentally reversed, so PIT calibration always failed
when PIT was present and always succeeded when PIT was missing, but in
the latter case resulted in absurdly fast clock.
Reported and tested by Vitaly Kuznetsov <vkuznets@redhat.com>
gnulib files are already handled by recursive make distdir invocation.
Including all generated headers (after make completed) causes build
failure if target system is different (different compile version etc).
Macports add extra information after version itself:
$flex --version
flex 2.5.35 Apple(flex-31)
We require at least felx 2.5.35 so do not need to care about prehistoric
"flex version n.n.n"; just use second field always.
Reported by Peter Cheung <mcheung63@hotmail.com>
PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.
Based on patch by Michael Chang.
