It is sort of a combination. You have to copy some files and then apply the main patch.
You git clone the repo and find the patch itself under "/target/linux/oxnas/patches-3.14".
Under "/target/linux/oxnas/files" you find the missing files or rather the directory structure that you need to copy directly into your kernel source tree.
And if I remember correctly that should be it.
Copy the files and then apply the patch.
@Daniel:
Anything else that needs to be done?
I am of course talking solely about compiling the kernel. Ignoring any other openwrt related stuff, as me personally, I am only interested in running Debian on my Pogos.
Of course I still HIGHLY value the work that kref and now you as a member of the openwrt community are doing and/or have been doing. ;-)

shv,
Have you tried this instruction ? also in the working thread at ALARM site, I recall some have succesfully prepared and booted with SATA.

bodhi,
I didn't try that yet. ALARM strategy was to put stage1 and uboot on specific sector location on the hard drive. Maybe I can just replace the uboot with the new one while using the old stage1 primary loader. I want to prevent a Fat32 partition just for boot files.
Another strategy could be to make a uboot_spl.bin primary loader for SATA which loads the uboot and uboot env from flash. Do you think that I can use your uboot.spl.bin for that strategy? What clock frequency set with your primary loader?

Shv,
I dont think my spl image works in SATA mode. But you could try. NAND and SATA versions are built differently. I'd doubt that it would work.

I've just found the same thing. There's compilation problem with FAT. I'm not sure yet but I think #define's has some problem when I use ox820_fat_config.

@shv,
I found an inconsistency between NAND and FAT compilation options. That was why the LED flashing code that I've added compiled for NAND but not for FAT. U-Boot has built OK now. Would you like to test it?

@shv,
I did not want to commit to GitHub before testing. I'm having problem booting with the SATA spl. It did not get loaded by ROM during powered up. I don't know if my eSata enclosure is the culprit or not (I don't have a 22 pin-eSATA+power cable to try a direct connect right now).
Here attached is the updated board/ox820/ox820.c file. You could try to rebuild with it. If you have any problem rebuilding, I could upload binaries to Dropbox.

I will try to get my mini pcie sata and/or USB3.0 controllers working with my Pogo V3 Pro the next few days. I am really interested in seeing how these will perform with the new kernel. Or first if they will work at all.
@shv:
Still very interesting to see that the old kernel performs best, when it comes to SATA..

@ingmar_k,
at least with ext4. Navym wrote somewhere that the performance of ext2 is much better.
you can find my performance tests on navyms kernel within some messages in the following thread: http://archlinuxarm.org/forum/viewtopic.php?f=55&t=6193&start=20#p35077
@bodhi,
the write perfomance compared with the older kernel form navym seams to be the same but the read performance seams to be a bit worse.

@shv,
Nice works! interesting to see the hard numbers. Have you tried Ext2 to see if read performance is back to normal?
@ingmar_k,
Indeed! I'm wondering could the OXNAS SATA driver be improved somehow.

Agree. That sounds very probable to me too. Too bad if we have to go back to Ext2 to get the performance back.

If I remember correctly, the old implementation also used some sort of caching mechanism.
Something maybe like CMA. That could account for the Performance difference.
@shv:
MAC-Address correctly set in /etc/network/Interfaces?
The error message reads a bit like the MAC address could not be determined and/or set. But I am just guessing.

@bodhi,
Yes, the MAC address is set in /etc/network/interfaces. I have one Squeeze rootfs where the folloing where the problem occurs if the MAC address in the boot environment and /etc/network/interfaces are the same. If I use certain values values it works.
With another Squeeze rootfs this "workaround" does not work.
There is no problem if I use my old kernel within both rootfs if "ethaddr" = "hwaddress ether".

@shv,
I do have both ethaddr and /etc/network/interfaces set to the same value. No problem on kernel 3.15.3. And it is the same rootfs that I have since squeeze.
I think if you look at serial console output closely, it might give out some hints.

I decided to play around with my other Pogoplug - this one is a non-PCI Pro model. I noticed that when I run fw_printenv, I get an ominous error message:
I don't have a serial cable, so I'm nervous about running fw_setenv and rendering the unit unbootable. Any tips?
Warning: Bad CRC, using default environment
bootcmd=bootp; setenv bootargs root=/dev/nfs nfsroot=${serverip}:${rootpath} ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}::off; bootm
bootdelay=5

Pls describe what are you trying to do, preferably with the full log. The CRC error usually indicates that the envs area in NAND has not been saved, therefore has no checksum.

Which uboot and which kernel are currently on the device? With the old uboot the netconsole doesn't work. With the old kernel you must use blparam instead of fw_setenv! If you have the old ALARM uboot and kernel image in the flash you could use my Wheezy rootfs: http://pogoplug.cwsurf.de/forum/viewtopic.php?f=5&t=114

agiorgio,
Did you follow a procedure, instruction …? which u-boot is currently on your Pogo? if not, which system were you running before, and what exactly did you do before seeing CRC error with fw_printenv?
There is not enough information, so a wrong advice could mess up your u-boot envs and brick your box!

The SATA performance issues come down to this:
The manufacturers kernel had hacked SATA transfers through the SRAM instead of DMA because the DMA is not directly hooked to the oxsemi SATA controller on the SoC. It was an ugly hack, but it made it work at a much better performance. Only problem, was it hit SO many inner workings of the kernel that it was a total PITA to port forward. I mean it hit A LOT.

The plug was running Debian Squeeze, and I replaced the root filesystem on the USB hard disk with shv's Wheezy one. That seemed to work perfectly. It's been a while since I hacked that plug to run Debian, and I don't remember exactly what I did. I'll probably end up just leaving it alone, since I'm just using it as a remote backup device.
