Hi All,

I released the RC5 of kernel 5.4 for the X1000 and X5000 today.

New:


Download: linux-image-5.4-rc5-X1000_X5000.tar.gz

BTW, I upgraded from a Radeon HD4870 to a HD6870 in my X5000/40 today. The HD6870 is a little bit faster but also a little bit louder. The interesting thing is, that the CPU temperature has decreased. With the HD4870 I had 80 degrees Celsius and with the HD6870 I have about 50 degrees Celsius CPU temperature. I think the Radeon HD4870 dissipated heat in the direction to the CPU.

Screenshot of the RC5 on a X5000/40 with a Radeon HD6870 (Barts XT):

Please test the kernels.

Thanks,
Christian

Many thanks! I added me to the CC List.

Link to the bug report: Bug 205201 - Booting halts if Dawicontrol DC-2976 UW SCSI board installed, unless RAM size limited to 3500M


Hi Roland,

I have the same problem with my analog PCI TV card Typhoon TView RDS + FM Stereo (BT878 chip) in my AmigaOne X5000. It only works with reducing the mem size to 3500MB (mem=3500M). I updated the bug report today.

Cheers,
Christian


Error message without limitation to 3.5G RAM:

Code: Select all

The kernel configured the bttv card for DMA in the upper region of RAM but the device believes that it only supports 32-bit addressing.

Hi All,

Here is the RC6 of kernel 5.4 for testing.

New:


Download: linux-image-5.4-rc6-X1000_X5000.tar.gz

Screenshot of Fedora 27 PPC64 with the RC6 of kernel 5.4 on an A-EON AmigaOne X5000/40:

Please test the kernels.

Thanks,
Christian

Kernel 5.4 RC6 running fine on the AmigaOne X5000

Also running Spiderweb with ViewTube plugin for HD video.

Network improvements... I managed to get around 170MB flowing through the DPAA X5000 onboard ethernet adapter before all traffic died... (which is much better than the previous kernels, but it is still broken)

FYI because of the issue with some PCI cards (SCSI, TV cards etc):

Subject: dma-direct: check for overflows on 32 bit DMA addresses

As seen on the new Raspberry Pi 4 and sta2x11's DMA implementation it is
possible for a device configured with 32 bit DMA addresses and a partial
DMA mapping located at the end of the address space to overflow. It
happens when a higher physical address, not DMAable, is translated to
it's DMA counterpart.

For example the Raspberry Pi 4, configurable up to 4 GB of memory, has
an interconnect capable of addressing the lower 1 GB of physical memory
with a DMA offset of 0xc0000000. It transpires that, any attempt to
translate physical addresses higher than the first GB will result in an
overflow which dma_capable() can't detect as it only checks for
addresses bigger then the maximum allowed DMA address.

Fix this by verifying in dma_capable() if the DMA address range provided
is at any point lower than the minimum possible DMA address on the bus.

Unfortunately this patch doesn't solve the issue. :-(
