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
Those:
CONFIG_PCIEPORTBUS=y
CONFIG_PHY_MTK_TPHY=y
are set, this:
CONFIG_PCIE_MEDIATEK=y
I cannot find in .config
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
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
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=yadded 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)
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
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?
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
Okay then try
git fetch linux
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.
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://[email protected]/frank-w/BPI-R2-4.14.git (fetch)

here i use git fetch stable
Working. I have produced RC3 kernel. Will try it at home

Both drives are mounted. Frank, I’m you big FAN !!!
Have you tried without the above patch?
Yes. Only your kernel + Linux 4.18 RC3 patch
Unfortunately, there are a lot of I/O errors. I will check another kernel tomorrow
Then try the patch above 
So far so good. With this patch is much better. None errors so far.
sorry, still errors.
This is my dmesg included
