| | | | | | | | | | | | | | | | | | | | 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".

* OvmfPkg: EFI handover flags are in Bp->hdr.xloadflagsMatt Fleming2013-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

* OvmfPkg: allocate the EFI memory map for Linux as Loader DataLaszlo Ersek2013-08-181-2/+6
| | | | | | | | | | | | | | | | | | | | | | 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".

* OvmfPkg: LoadLinuxLib: Fix kernel entry for 64-bit OVMFjljusten2013-01-142-6/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
