Hi,
i have tried to kexec a 32 bit kernel on a Freescale P2020 dual core CPU
(e500v2, revison 5.1 - pvr 8021 1051), but Kexec will hang after the
"Bye!".
The host and the kexec kernel are the same, based on the current kernel
version 3.10.
I have tried it with kexec-tools 2.0.4.git released 30 June 2013.
Invoking kexec with
kexec --command-line "1 maxcpus=1 noirqdistrib reset_devices $(cat /proc/cmdline)" -t elf-ppc --dtb=rs2020.dtb \
--reuse-node="/cpus/PowerPC,P2020@0/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/cpu-release-addr" \
--reuse-node="/cpus/PowerPC,P2020@1/enable-method" \
--reuse-node="/soc@ffe00000/bus-frequency" \
--reuse-node="/soc@ffe00000/serial@4500/clock-frequency" \
--reuse-node="/soc@ffe00000/ethernet@24000/local-mac-address" \
-d -l -x vmlinux
kexec -e
This will be the result output of the run:

Kexec is still working on a Freescale 834x PowerPC CPU and the output
of kexec looks similary.
Any ideas?

No, I think this is not interdicted.
I suspect you probably don't pass a proper dtb, so you can take a further test
to figure out this problem.
For example, in the u-boot prompt, you can use the fdt command to get last dtb
after that board setup from u-boot, then pass that directly to try.

Great, this works.
I did more test and the issue for the fail is the passing of the device
tree. But the device tree is exact the same as the previous used one.
Is passing a new device tree not allowed?

* BUG: 32 Bit Kernel kexec hangs on P2020

Hi,
i have tried to kexec a 32 bit kernel on a Freescale P2020 dual core CPU
(e500v2, revison 5.1 - pvr 8021 1051), but Kexec will hang after the
"Bye!".
The host and the kexec kernel are the same, based on the current kernel
version 3.10.
I have tried it with kexec-tools 2.0.4.git released 30 June 2013.
Invoking kexec with
kexec --command-line "1 maxcpus=1 noirqdistrib reset_devices $(cat /proc/cmdline)" -t elf-ppc --dtb=rs2020.dtb \
--reuse-node="/cpus/PowerPC,P2020@0/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/cpu-release-addr" \
--reuse-node="/cpus/PowerPC,P2020@1/enable-method" \
--reuse-node="/soc@ffe00000/bus-frequency" \
--reuse-node="/soc@ffe00000/serial@4500/clock-frequency" \
--reuse-node="/soc@ffe00000/ethernet@24000/local-mac-address" \
-d -l -x vmlinux
kexec -e
This will be the result output of the run:

[ 46.506211] Bye!
Kexec is still working on a Freescale 834x PowerPC CPU and the output
of kexec looks similary.
Any ideas?

* BUG: 32 Bit Kernel kexec hangs on P2020

Hi,
i have tried to kexec a 32 bit kernel on a Freescale P2020 dual core CPU
(e500v2, revison 5.1 - pvr 8021 1051), but Kexec will hang after the
"Bye!".
The host and the kexec kernel are the same, based on the current kernel
version 3.10.
I have tried it with kexec-tools 2.0.4.git released 30 June 2013.
Invoking kexec with
kexec --command-line "1 maxcpus=1 noirqdistrib reset_devices $(cat /proc/cmdline)" -t elf-ppc --dtb=rs2020.dtb \
--reuse-node="/cpus/PowerPC,P2020@0/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@0/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/timebase-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/bus-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/clock-frequency" \
--reuse-node="/cpus/PowerPC,P2020@1/next-level-cache" \
--reuse-node="/cpus/PowerPC,P2020@1/cpu-release-addr" \
--reuse-node="/cpus/PowerPC,P2020@1/enable-method" \
--reuse-node="/soc@ffe00000/bus-frequency" \
--reuse-node="/soc@ffe00000/serial@4500/clock-frequency" \
--reuse-node="/soc@ffe00000/ethernet@24000/local-mac-address" \
-d -l -x vmlinux
kexec -e
This will be the result output of the run:
