Hi All,

The RC1 of kernel 5.9 is available for the X1000 and X5000.

New:

• Linux 5.9-rc1 Kernel Released - Line Count Dominated By AMD Radeon Navi 2 Additions -- phoronix.com
• Linux 5.9 Features New GPU Support To Numerous Security + Performance Optimizations -- phoronix.com
• Linux 5.9-rc1 release announcement
• Linux Git log
• Phoronix articles, reviews and news stories covering Linux 5.9

Issues:

• Virtual e5500 QEMU machine with a VirtIO-GPU: The issue with the VirtIO-GPU still exists. Therefore we still need the virtio_gpu patch.
• X5000: We still need the dpaa-v1 patch because of the DPAA issue on Ubuntu 16.04.

Download: linux-image-5.9-rc1-X1000_X5000.tar.gz



Please test the kernels.

Thanks,
Christian

Thank you!

@All
Great news because of the issue with the VirtIO-GPU.

It is fixed in drm-misc-next (commit 51c3b0cc32d2e17581fce5b487ee95bbe9e8270a).

Will cherry-pick into drm-misc-fixes once the branch is 5.9-based, which
in turn should bring it to 5.9-rc2 or -rc3.

take care,
Gerd

Hi All,

I compiled a new kernel with the latest DRM misc updates today.

Code: Select all

git clone git://cgit.freedesktop.org/drm/drm-misc.git a

Our patch is included in these updates.

Download: linux-image-5.9-rc1-2-X5000.tar.gz

This kernel works with the VirtIO-GPU in a virtual e5500 QEMU/KVM HV machine on my X5000.

Unfortunately I can only use the VirtIO-GPU (Monitor: Red Hat, Inc. 8") with a resolution of 640x480. If I set a higher resolution then the guest disables the monitor. I can use higher resolutions with the stable kernel 5.8 and the VirtIO-GPU.

I reported this issue to the kernel developers today. Link: [Virtual ppce500] virtio_gpu virtio0: swiotlb buffer is full

Cheers,
Christian

Hi All,

Gerd released a patch because of the resolution issue with the VirtIO-GPU yesterday.

Hi All,

I compiled a new RC1 with Gerd's and our patch today. With these patches, the VirtIO-GPU works without any problems. I can use higher resolutions again.

Download: linux-image-5.9-rc1-3-X5000.tar.gz
