BPI-R2-Kernel 4.18


(Frank W.) #21

i’m currently not at home, can you look if in config (./build.sh config) these options are set:

CONFIG_PCIEPORTBUS=y
CONFIG_PCIE_MEDIATEK=y
CONFIG_PHY_MTK_TPHY=y

? the new folder is always included by makefile in drivers/pci and option for PCIe-Mediatek is not changed as far as i see


(Maciek Szelągowski) #22

Those:

CONFIG_PCIEPORTBUS=y

CONFIG_PHY_MTK_TPHY=y

are set, this:

CONFIG_PCIE_MEDIATEK=y

I cannot find in .config


(Frank W.) #23

maybe it depends on another…make

./build.sh config

and press / to search for it… you get the option and there is a depends on-line

any error on importconfig?

from Kconfig:

depends on ARCH_MEDIATEK || COMPILE_TEST  <<< ARCH_MEDIATEK should be set
depends on OF <<< maybe not
depends on PCI_MSI_IRQ_DOMAIN <<<maybe not

try searching for the last 2 options and try to set…

for comparision 4.16-main (same in 4.17-main):

depends on (ARM || ARM64) && (ARCH_MEDIATEK || COMPILE_TEST)
depends on OF
depends on PCI
select PCIEPORTBUS

so i assume OF is set (imho also needed for wifi)…PCI_MSI_IRQ_DOMAIN is not needed here, so this can be missing


(Maciek Szelągowski) #24

OF is set

but I cannot find PCI_MSI_IRQ_DOMAIN even if I grep through .config file

but it’s when I use /find in config


(Frank W.) #25

so we have the right configuration, you can try it setting before the PCIE_MEDIATEK in arch/arm/configs/*fwu_defconfig and make importconfig again

CONFIG_PCI_MSI_IRQ_DOMAIN=y
CONFIG_PCIE_MEDIATEK=y

if you find it in menuconfig (./build.sh config) you can post ne the infos (Kconfig-Path), so i can find it in source

drivers/pci/Kconfig:

config PCI_MSI
	bool "Message Signaled Interrupts (MSI and MSI-X)"
	depends on PCI
	select GENERIC_MSI_IRQ
...
config PCI_MSI_IRQ_DOMAIN
	def_bool ARC || ARM || ARM64 || X86  //what is def_bool?
	depends on PCI_MSI
	select GENERIC_MSI_IRQ_DOMAIN

so wen need this block in defconfig:

CONFIG_PCI_MSI=y
CONFIG_PCI_MSI_IRQ_DOMAIN=y //maybe this is set by PCI_MSI by default
CONFIG_PCIE_MEDIATEK=y

(Frank W.) #26

added PCI_MSI for PCIE_MEDIATEK in 4.18-rc and 4.18-wlan

after “./build.sh importconfig” PCIE_MEDIATEK is set to y

hope this solves your issue

can you also try without the patch above? (this is currently not in my repo)


(Maciek Szelągowski) #27

can you please explain me how to merge current 4.18-rc3 from Linus to your repo which I cloned localy 4.18-wlan?

I found I should do it like:

git checkout master

git merge origin/aRemoteBranch

or course should replace:

git checkout 4.18-wlan

but what to replace here?:

git merge origin/aRemoteBranch


(Frank W.) #28

i have only included stable-tree, but this should work

git fetch torvalds/master #maybe torvalds:master
git merge v4.18-rc3 #merge the tag not the branch

my repo also contains a master-branch at rc1 so merging “master” will not lead to expected results

have you tried sata with my last changes?


(Maciek Szelągowski) #29

msze@dvig0472:~/BPI-R2-4.14$ git fetch torvalds/master

fatal: ‘torvalds/master’ does not appear to be a git repository

fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

same for torvalds:master

msze@dvig0472:~/BPI-R2-4.14$ git remote -v

linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git (fetch)

SATA I will try this afternoon


(Frank W.) #30

Okay then try

git fetch linux


(Maciek Szelągowski) #31

msze@dvig0472:~/BPI-R2-4.14$ git fetch linux

fatal: ‘linux’ does not appear to be a git repository

fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.


(Frank W.) #32
git fetch linus

First value in git remote -v should be name of remote repo.this depends on how you’ve added the remote repo.

for comparision here my git remote-config

$ git remote -v
origin	https://frank-w@github.com/frank-w/BPI-R2-4.14.git (fetch)
origin	https://frank-w@github.com/frank-w/BPI-R2-4.14.git (push)
stable	https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git (fetch)
stable	https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git (push)

here i use git fetch stable


(Maciek Szelągowski) #33

Working. I have produced RC3 kernel. Will try it at home

(Frank W.) #35

Have you tried without the above patch?


(Maciek Szelągowski) #36

Yes. Only your kernel + Linux 4.18 RC3 patch


(Maciek Szelągowski) #37

Unfortunately, there are a lot of I/O errors. I will check another kernel tomorrow


(Frank W.) #38

Then try the patch above :slight_smile:


(Maciek Szelągowski) #39

So far so good. With this patch is much better. None errors so far.


(Maciek Szelągowski) #40

sorry, still errors.

This is my dmesg included
