I think ldo7 and ldo6 are related with hdmi from schematic. Thanks.

I think ldo7 and ldo6 are related with hdmi > from schematic. Nice catch. I followed hardkernels dts here, which refers to ldo10 & ldo8, however double-checking the schematics indeed indicate that ldo7 and ldo6 are used the HDMI supplies. I'll do some testing and follow-up
Hi Sjoerd, I am using 3.18.0 kernel on my odroidxu3 board. Using exynos_defconfig I am able to boot the board. Are you able to get all the 8 core CPU up and running ? Only 4 core cpu's are on my board. Also CpuFreq is not working. Can you share some point on this. root@odroid-xu3:/usr/src/odroidxu3-3.18.y-debug# cat /proc/cpuinfo | grep processor processor : 0 processor : 5 processor : 6 processor : 7 Below are the logs of the board.

I followed hardkernels dts here, which refers to ldo10 & ldo8, however double-checking the schematics indeed indicate that ldo7 and ldo6 are used the HDMI supplies. I'll do some testing and follow-up

That configuration is appropriate for the 5420, which allegedly has a hardware bug in the cache-coherence between the Cortex-A7 block and the Cortex-A15 block. Newer Exynos 5 SoCs -- 5422/5800, 5620, etc -- don't have that bug. The scheduler should configured to do HMP on all 8 (or 6) cores. I don't have a 5410, but I assume it has the same bug as the 5420. The XU3 kernel supplied by HardKernel shows all 8 cores, and does HMP scheduling across all 8. I tried v1.0 of the Odroid-XU3 DTB patch, applied to linux-next 20150107. I'm only seeing 1 core running on my Odroid-XU3. The USB 3.0 port works (great!) but I'm not getting any HDMI output. I didn't try DisplayPort. I'll gladly try v2 of the patch on an XU3; is there a better base to apply the patch to?

Yes the kernel/scheduler could be configured like that, but exynos_defconfig turns on bL rather then HMP. Now it's not unthinkable to add code/dts properties to select the right/preferred scheduling strategy depending on the board (HMP vs. bL). But proper HMP scheduling is still a work in progress in mainline and iirc specifically on the XU3 there are open issue wrt. MCPM and its secure firmware. I've added Kevin to the CC as he's been working on this topic so should know the status a lot better then i do. > The XU3 kernel supplied by HardKernel shows all 8 cores, and does HMP scheduling across all 8. Yes, that's independant of the dts though as mentioned above. Also there are still opne issues to booting up all cores on an XU3 afaik.

HDMI output is broken on all exynos boards in mainline atm. For exynos 5, see the thread here: http://www.spinics.net/lists/linux-samsung-soc/msg40708.html As far as a i know with the DTS as posted (just posted v3 with a small improvement), all base functionality that can work on mainline (MMC/SD, network, USB2, USB3) works. Some less important bits (fan control & power sensors) are outstanding, but that really shouldn't block the merge of the DTS. -- Sjoerd Simons <sjoerd.simons@collabora.co.uk> Collabora Ltd.

Yes the kernel/scheduler could be configured like that, but exynos_defconfig turns on bL rather then HMP. Now it's not unthinkable to add code/dts properties to select the right/preferred scheduling strategy depending on the board (HMP vs. bL). But proper HMP scheduling is still a work in progress in mainline and iirc specifically on the XU3 there are open issue wrt. MCPM and its secure firmware.

Yes, that's independant of the dts though as mentioned above. Also there are still opne issues to booting up all cores on an XU3 afaik.

HDMI output is broken on all exynos boards in mainline atm. For exynos 5, see the thread here: http://www.spinics.net/lists/linux-samsung-soc/msg40708.html As far as a i know with the DTS as posted (just posted v3 with a small improvement), all base functionality that can work on mainline (MMC/SD, network, USB2, USB3) works. Some less important bits (fan control & power sensors) are outstanding, but that really shouldn't block the merge of the DTS. -- Sjoerd Simons <sjoerd.simons@collabora.co.uk> Collabora Ltd.

If you turn the switcher off, you will indeed get all 8 cores, but you may get some rather strange and sub-optimal results with performance since from the scheduler perspective, it will balance tasks across all 8 CPUs as if they were identical. > and iirc specifically on the XU3 there are open issue wrt.

The broken firmware issues don't affect scheduling directly, but affect the low-power states that are available to the kernel. Since the firwmware doesn't allow proper access to CCI, low-power states that require MCPM are not available, which, among other things, means the clusters can not be powered down. >> The XU3 kernel supplied by HardKernel shows all 8 cores, and does HMP scheduling across all 8. > > Yes, that's independant of the dts though as mentioned above.

See > http://www.spinics.net/lists/linux-samsung-soc/msg39523.html I haven't looked closely at the hardkernel tree to see what HMP scheduling patches they're using, but it must be something out of tree.

Add DTS for the Hardkernel Odroid XU3. The name of the DTS file is kept the same as the vendors naming, which means it's prefixed with exynos5422 instead of exynos5800 as the SoC name even though it includes the exyno5800 dtsi. Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> --- Changes since v1: * Add chosen/linux,stdout-path to point the serial console device * Change memory start offset to 0x40000000 to match the vendors DTS (pointed out by Heesub Shin) * Declare base address & size for the memory banks to be used by the MFC Kevin, Tyler, even though the changes are small i didn't want to just stick your Tested-By on. Could you both be so kind to retest this on your XU3's ? Heesub, I would still love to know the reason for having the memory start address at 0x40000000 for this board? arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/exynos5422-odroidxu3.dts | 332 +++++++++++++++++++++++++++++ 2 files changed, 333 insertions(+) create mode 100644 arch/arm/boot/dts/exynos5422-odroidxu3.dts
