Laszlo Ersek c63bcc2e4b OvmfPkg/LoadLinuxLib: list "LoadLinuxLib.h" in the INF file
The header file declares the InitLinuxDescriptorTables() and
SetLinuxDescriptorTables() functions, which are called from "Linux.c" and
implemented in "LinuxGdt.c".

The header file also declares the JumpToKernel() and JumpToUefiKernel()
functions, which are similarly called from "Linux.c". They are implemented
(dependent on architecture) in "Ia32/JumpToKernel.nasm" and
"X64/JumpToKernel.nasm".

Matt Fleming b1362258ef OvmfPkg: EFI handover flags are in Bp->hdr.xloadflags
LoadLinux() is looking at the wrong field for the kernel's EFI handover
protocol flags. It's not currently possible for JumpToUefiKernel() to
ever be called (even accidentally) because BIT2 and BIT3 of
Bp->hdr.load_flags are never set in modern kernels, which means that
control is always transferred to the kernel via the legacy entry point.

Look at the correct field so that the EFI handover protocol is used
whenever it's available.

Laszlo Ersek 4388b0ee0c OvmfPkg: allocate the EFI memory map for Linux as Loader Data
In Linux, efi_memblock_x86_reserve_range() and efi_reserve_boot_services()
expect that whoever allocates the EFI memmap allocates it in Loader Data
type memory. Linux's own exit_boot()-->low_alloc() complies, but
SetupLinuxMemmap() in LoadLinuxLib doesn't.

The memory type discrepancy leads to efi_memblock_x86_reserve_range() and
efi_reserve_boot_services() both trying to reserve the range backing the
memmap, resulting in memmap entry truncation in
efi_reserve_boot_services().

This fix also makes this allocation consistent with all other persistent
allocations in  "OvmfPkg/Library/LoadLinuxLib/Linux.c".

linker is not a fan of relocations so it is better to us IP
relative code, but at least it removes a relocation entry.

We're supposed to zero everything in the kernel bootparams that we don't

for a precisely defined length, which is copied from the bzImage.

We're *not* supposed to just pass the garbage that we happened to find
in the bzImage file surrounding the setup_header.

jljusten 61a114ba46 OvmfPkg: LoadLinuxLib: Fix kernel entry for 64-bit OVMF
We currently just jump to offset 0x200 in the kernel image, in 64-bit
mode. This is completely broken. If it's a 32-bit kernel, we'll be
jumping into the compressed data payload.

If it's a 64-bit kernel, it'll work... but the 0x200 offset is
explicitly marked as 'may change in the future', has already changed
from 0x100 to 0x200 in the past with no fanfare, and bootloaders are
instructed that they should look at the ELF header to find the offset.
So although it does actually work today, it's still broken in the
"someone needs to whipped for doing it this way" sense of the word.

In fact, the same bug exists in other bootloaders so the 0x200 offset
probably *is* now set in stone. But still it's only valid to use it if
we *know* it's a 64-bit kernel. And we don't. There *is* no ELF header
that we can look at when we're booting a bzImage, and we can't rely on
it having a PE/COFF header either.

The 32-bit entry point is always guaranteed to work, and we need to
support it anyway. So let's just *always* use it, in 32-bit mode, and
then we don't have to make up some horrible heuristics for detecting
32-bit vs. 64-bit kernels.
