Hi All,
I have seen that I have activated the kernel config option CONFIG_ARCH_DMA_ADDR_T_64BIT. That means the code in the following patch won't work if this kernel option is enabled.
Code: Select all
+#ifndef CONFIG_ARCH_DMA_ADDR_T_64BIT
+ /* Check if DMA address overflowed */
+ if (min(addr, addr + size - 1) <
+ __phys_to_dma(dev, (phys_addr_t)(min_low_pfn << PAGE_SHIFT)))
+ return false;
+#endif
I will delete the lines with ifndef and endif and will try it again.
Cheers,
Christian

Now, I can definitely say that this patch does not solve the issue.

Hi All,
The
RC7 of kernel
5.4 has been released for testing.
New:
Download:
linux-image-5.4-rc7-X1000_X5000.tar.gz
Please note: There are problems with some PCI cards if you have more than 3.5G RAM in your X5000. If you have this problem please reduce the RAM with the boot argument "mem=3500M". The X1000 isn't affected. We created a bug report a month ago. Link to the bug report:
Bug 205201 - Booting halts if Dawicontrol DC-2976 UW SCSI board installed, unless RAM size limited to 3500M
BTW, a new version of ViewTube with new settings is available.
Screenshot of Fienix PowerPC with the kernel 5.4-rc7 and with the new ViewTube:
Please test the kernels.
Thanks,
Christian

Skateman,
Good to know that your PCI cards work (see your screenshot).
Cheers,

I have also had the PCI problems before and changed the PCI Soundblaster card back then...

Hi All,
Great news!
The issue with the BT878 TV cards is solved.
GFP_DMA32 was renamed to GFP_DMA in the PowerPC updates 4.21-1 in December last year.
Some PCI devices still use GFP_DMA32 (grep -r GFP_DMA32 *). I renamed
GFP_DMA32 to
GFP_DMA in the file "
drivers/media/v4l2-core/videobuf-dma-sg.c".
After compiling the RC7 of kernel 5.4, my BT878 TV card works again.
I created a patch for renaming GFP_DMA32 to GFP_DMA.
Code: Select all
--- a/drivers/media/v4l2-core/videobuf-dma-sg.c 2019-11-11 01:17:15.000000000 +0100

- page = alloc_page(GFP_USER | __GFP_DMA32);
+ page = alloc_page(GFP_USER | __GFP_DMA);
if (!page)
return VM_FAULT_OOM;
clear_user_highpage(page, vmf->address);
I compiled the
RC7-2 with this patch for testing today.
