Operating Systems and Porting / Re: [NEWS] Linux 5.10 LTS
« Last post by MauryG5 on January 20, 2021, 06:43:41 am »
Hi TLE, yes, you too try to do the same thing.  I have changed only 2 options of all those that are available in the Kernel that is, CPU used, the Kernels of various distributions must leave Power 8 because they must maintain compatibility with it, we can put Power 9 without problems, then in the Kernel settings  , where it says page size, I change the 64K which is default to 4K.  I don't do anything else and I got both Fedora and Ubuntu working and Pocock started Debian.  So it is evident that the real problem is the size of the pages, evidently the new drivers of these graphics cards have as a feature the change from 64K to 4K and that's why there are these continuous problems ... They leave the page size at 64K,  I also looked at all the settings of the latest Fedora Kernels made by them ...

Intriguing! Okay I'll give 4k page size a go this weekend and see if that would address the regression issue I am having with my R9 Nano card

Guys, I also compiled the Kernel for Ubuntu and as you can see, I can use perfectly and finally I would say also, the Navi 10 GPU. I put the new and just released 5.10.8, it seems that it works well, I am very happy with the results obtained , Pocock was absolutely right, just use the pages in 4K and all distros start working perfectly on Navi 10!

Talos II / Is the Intel "8-Port PCIe Gen3 x8 Switch AIC" HBA controller compatible?
« Last post by ullbeking on January 18, 2021, 09:48:27 am »
Hello,

There has been a LOT of discussion in various forums, especically https://forums.servethehome.com/index.php, about which combinations of PLX-switched HBA controllers and U.2 SSD drive cages (1x 5.25" slot for 4x 2.5" SSD's; 2x 5.25" slots for 8x 2.5" SSD's) are compatible.  There is still no definitive answer, but I would like to find one for my use case...

Is the Intel AXXP3SWX08080 ("8-Port PCIe Gen3 x8 Switch AIC") (https://ark.intel.com/content/www/us/en/ark/products/124459/8-port-pcie-gen3-x8-switch-aic-axxp3swx08080.html) compatible with a Talos II (x8) PCI-e slot?

I didn't see any mention of this in the wiki.  Could somebody please shed some light?  Thanks!!

Applications and Porting / Re: Chromium and Ungoogled Chromium DNF Repository

Sorry guys but what happened to Chromium on Power? How come we are stuck at version 84.0.4147.125 and it doesn't update anymore? Has something happened or you have to run some new repository installation that I don't know?

Grrr, that sounds like kvm_pr got broken again. I'll take a look.

Applications and Porting / QEMU accel=kvm not able to boot guest Mac OS X
« Last post by Logout on January 16, 2021, 06:09:26 am »
Hello everyone!

I wonder if anyone else ever had the same problem as I do: I'm not able to boot any Mac OS X version with KVM accelerator enabled.
More details:

Machine: 8-core Blackbird, 32G RAM
Kernel&host OS: right now 5.10.6 under Riscy Slack, but before that whatever was current in Void Linux during last months, kvm and kvm_pr both present and loaded
QEMU: 5.2.0, but also 4.1.1 and 5.0.0
Mac OS X: 10.3, 10.4, 10.5, 10.5.2

What happens? MacOS X starts booting, after a while it reaches the point where it reports BSD root: disk0s3, major 14, minor 2 and hangs there. I discovered how to make qemu report errors, this is what happens:

The commandline is: taskset -a -c 0-3 ./qemu-system-ppc -cpu nitro -M mac99,accel=kvm,via=pmu -m 512 -prom-env boot-args=-v -boot c -drive file=leopard.img,format=qcow2,l2-cache-size=4M -usb -device usb-tablet -g 1280x1024x32  -d unimp,guest_errors

The tcg accelerator works, I installed the system from DVD through it as with KVM not even that boots. Thanks for any advice!

Kernel 5.10.7, compiled and just tested. Compared to 5.9.16, it automatically switches to the video output of the AMD Navi 10 GPU and appears not to suffer from the fatal freeze bug when it goes to black screen to switch video output.
Also in this case I chose the solution of the pages in 4K and I left Wayland active.

Firmware / Re: talos-openbmc: build failure
« Last post by resonant on January 15, 2021, 11:18:36 am »
holy brittle build toolchain, batman!

the fix here ended up being to determine which bitbake recipes were responsible for the missing files, then forcing a clean and install on those specific recipes:

bitbake -f -b /home/user/talos-openbmc/meta-rcs/recipes-phosphor/binary-block-editor/binary-block-editor.bb -c clean
bitbake -f -b /home/user/talos-openbmc/meta-rcs/recipes-phosphor/binary-block-editor/binary-block-editor.bb -c install

i also had to do the same for meta-aspeed/recipes-bsp/u-boot/u-boot-fw-utils-aspeed_2016.07.bb. after this, you can restart the build with the usual bitbake obmc-phosphor-image command.

this really should be documented in the wiki so anyone else having the same issues doesn't have to figure out how bitbake works.
