Subject: [PATCH] [PATCH] Implement kexec-hardboot
"Allows hard booting (i.e., with a full hardware reboot) to a kernel
previously loaded in memory by kexec. This works around the problem of
soft-booted kernel hangs due to improper device shutdown and/or
reinitialization."
More info in /arch/arm/Kconfig.
Original author: Mike Kasick <mike@kasick.org>
Vojtech Bocek <vbocek@gmail.com>:
I've ported it to hammerhead, it is based of my mako/grouper port, which is
based of Asus TF201 patch ported by Jens Andersen <jens.andersen@gmail.com>
Hammerhead is the first device I've ported this patch to which uses
device tree binary instead of atags. It is also rather picky - its
bootloader erases first 128MB of RAM on reboot, so following hacks had
to be applied:
* Copy dtb to location passed in r2 before jumping to kexecd' kernel,
the kernel would just freeze when I left dtb above 128MB of RAM.
* Copy kexecd' kernel to location in the first 128MB before jumping to it,
the decompressor operates very slowly if the kernel is above the cached
area, copying it lower and decompressing it afterwards is much faster.
Same as my mako/flo patches, the guest kernel does not require any
modifications, kexec-hardboot is equivalent to standard kexec.
To support dtb, following commit was backported from the mainline:
commit 4cabd1d9625c7d88acd143f4021fbef75394f154

ARM: 7539/1: kexec: scan for dtb magic in segments
This patch allows a dtb to be passed to a new kernel using the kexec
mechinism.
When loading segments from userspace, scan each segment's first four
bytes for the dtb magic. If this is found set the kexec_boot_atags
parameter to the relocate_kernel code to the phyical address of this
segment.

+config KEXEC_HARDBOOT
+ bool "Support hard booting to a kexec kernel"
+ depends on KEXEC
+ help
+ Allows hard booting (i.e., with a full hardware reboot) to a kernel
+ previously loaded in memory by kexec. This works around the problem of
+ soft-booted kernel hangs due to improper device shutdown and/or
+ reinitialization. Support is comprised of two components:
+
+ First, a "hardboot" flag is added to the kexec syscall to force a hard
+ reboot in relocate_new_kernel() (which requires machine-specific assembly
+ code). This also requires the kexec userspace tool to load the kexec'd
+ kernel in memory region left untouched by the bootloader (i.e., not
+ explicitly cleared and not overwritten by the boot kernel). Just prior
+ to reboot, the kexec kernel arguments are stashed in a machine-specific
+ memory page that must also be preserved. Note that this hardboot page
+ need not be reserved during regular kernel execution.
+
+ Second, the zImage decompresor of the boot (bootloader-loaded) kernel is
+ modified to check the hardboot page for fresh kexec arguments, and if
+ present, attempts to jump to the kexec'd kernel preserved in memory.
+
+ Note that hardboot support is only required in the boot kernel and any
+ kernel capable of performing a hardboot kexec. It is _not_ required by a
+ kexec'd kernel.

Should the atags used to boot the kernel be exported in an "atags"
file in procfs. Useful with kexec.
+config KEXEC_HARDBOOT
+ bool "Support hard booting to a kexec kernel"
+ depends on KEXEC
+ help
+ Allows hard booting (i.e., with a full hardware reboot) to a kernel
+ previously loaded in memory by kexec. This works around the problem of
+ soft-booted kernel hangs due to improper device shutdown and/or
+ reinitialization. Support is comprised of two components:
+
+ First, a "hardboot" flag is added to the kexec syscall to force a hard
+ reboot in relocate_new_kernel() (which requires machine-specific assembly
+ code). This also requires the kexec userspace tool to load the kexec'd
+ kernel in memory region left untouched by the bootloader (i.e., not
+ explicitly cleared and not overwritten by the boot kernel). Just prior
+ to reboot, the kexec kernel arguments are stashed in a machine-specific
+ memory page that must also be preserved. Note that this hardboot page
+ need not be reserved during regular kernel execution.
+
+ Second, the zImage decompresor of the boot (bootloader-loaded) kernel is
+ modified to check the hardboot page for fresh kexec arguments, and if
+ present, attempts to jump to the kexec'd kernel preserved in memory.
+
+ Note that hardboot support is only required in the boot kernel and any
+ kernel capable of performing a hardboot kexec. It is _not_ required by a
+ kexec'd kernel.
