Linux kernel EGP_PGT_DUMP build option

Sai Praneeth Prakhya of Intel submitted V2 of an Intel UEFI diagnostic patch for the Linux kernel, the new version adds x86 support.

[PATCH V2] x86/efi: Add EFI_PGT_DUMP support for x86_32, kexec
EFI_PGT_DUMP, as the name suggests dumps efi page tables to dmesg during kernel boot. This feature is very useful while debugging page faults/null pointer dereferences to efi related addresses. Presently, this feature is limited only to x86_64, so let’s extend it to other efi configurations like kexec kernel, efi=old_map and to x86_32 as well. This doesn’t effect normal boot path because this config option should be used only for debug purposes.

Changes since v1:
1. Call efi_dump_pagetable() only once from efi_enter_virtual_mode() – as suggested by Boris

For more info, see the patch on the linux-(kernel,efi) lists.

Debian Live images now include UEFI support

Steve McIntyre gave an update on Debian official images to the debian-(cd, devel-announce,live,cloud) mailing lists. There’s a UEFI update on Debian Live images:
Live images – now including UEFI support

After a hiatus, weekly builds of live images for testing are now happening again. These cover amd64 and i386, and there is a separate image for each of the common desktop environments. Thanks to great work by Neil Williams, Iain Learmonth and Ana Custura on new tools (vmdebootstrap and live-wraper), these also include support for UEFI booting as a new feature. Please help test the images and give feedback:
