This is wrong; there are other devices that are used on Tegra that
require the noncached memory pool, e.g. the r8169 device.
Isn't r8169 PCI device ? Shouldn't the r8169 driver be fixed instead ?
IIRC, the r8169 hardware doesn't have the same descriptor stride
capability that the EQoS hardware does, so it isn't possible to fix that
driver. Thierry Reding may remember more details since IIRC he worked on
adding the noncached support to the r8169 driver; see d58acdcbfb33 "net:
rtl8169: Use non-cached memory if available".
But rtl8169 is PCI device, should that even be affected at all ?
I'll try and test this patch with the EQoS driver later today.
The testing passed:-)
Thank you
