Hi,
(please cc me on replies)
We have a user that tried out b43, but got this in the logs:
--- cut ---
65858:Feb 9 22:05:16 elmo kernel: b43-phy2 ERROR: This device does not
support DMA on your system. Please use PIO instead. 65859:Feb 9
22:05:16 elmo kernel: b43-phy2 ERROR: CONFIG_B43_FORCE_PIO must
be set in your kernel configuration.
65860:Feb 9 22:05:16 elmo kernel: b43-phy2 debug: Adding Interface type 2

--- cut ---
But reading the Kconfig help, it states:
--- cut ---
config B43_FORCE_PIO
bool "Force usage of PIO instead of DMA"
depends on B43 && B43_DEBUG
---help---
This will disable DMA and always enable PIO instead.
Say N!
This is only for debugging the PIO engine code. You do
_NOT_ want to enable this.
--- cut ---
So,
wich one is it ?
Do I belive the dmesg output, or the Kconfig ?
Note,
the b43 works for the user if he enable the CONFIG_B43_FORCE_PIO.
But I'm thinking of this problem from a distro point of view.
Will it break for others if I enable it ?
