2014-03-07gpt-auto-generator: automatically find the root disk of the systemLennart Poettering
When run in an initrd and no root= argument is set (or is set to root=gpt-auto) we will automatically look for the root partition on the same disk the EFI ESP is located on. Since we look for swap, /home and /srv on the disk the root partition is located on, we hence have a fully discoverable chain: Firmware discovers the EFI ESP partition → the initrd discovers the root partition → the host OS discovers swap, /home, and /srv. Note that this requires an EFI boot loader that sets the LoaderDevicePartUUID EFI variable, such as Gummiboot.
2014-02-19make gcc shut upLennart Poettering
If -flto is used then gcc will generate a lot more warnings than before, among them a number of use-without-initialization warnings. Most of them without are false positives, but let's make them go away, because it doesn't really matter.

Fixes minor leak in error path in device.c.
2013-10-13Never call qsort on potentially NULL arraysZbigniew Jędrzejewski-Szmek
This extends 62678ded 'efi: never call qsort on potentially NULL arrays' to all other places where qsort is used and it is not obvious that the count is non-zero.

2013-09-24support acpi firmware performance data (FPDT)Kay Sievers
Prefer firmware-provided performance data over loader-exported ones; if ACPI data is available, always use it, otherwise try to read the loader data. The firmware-provided variables start at the time the first EFI image is executed and end when the operating system exits the boot services; the (loader) time calculated in systemd-analyze increases.

2013-02-13efi: efi_get_boot_options() should already sort the entries, the random ↵Lennart Poettering
order in the efivars fs is probably not useful This also introduces a new FOREACH_DIRENT macro and makes use of it.

2013-01-19core: if the bootloader supports it, determine firmware and boot loader delayLennart Poettering
This allows us to print simple performance data of all parts of the boot now: - firmware - boot loader - kernel - initrd - userspace This only works for bootloaders which support passing TSC data via EFI variables. As of now that's only gummiboot.
