Activating Afterburner (125Mbps) on the recent wl-500g units

[Oleg]

Well, yet another piece of information.

The utility above does not work with bcm4712 based units (wrt54g v2.0), so probably most have just downloaded it, tried to run and thinked this utility is a fake. Very Happy

Further investigation using the info provided by Kaloz (thanks!) showed, that 4712 does not have a srom mapped to the PCI, instead flags showed that 4306 on the silicon backplane bus. But according to broadcom sources it's not possible to access srom this bus. Shocked

With help of Kaloz, I've discovered, that instead boardflags are stored in the nvram.
For his board boardflags == 0x0188, I've suggested him to turn magic afterburner bit with

nvram set boardflags=0x0388
nvram commit

and reload the wl.o module. And magically, wl.o has enabled afterburner on his wrt54g v2.0:

<Kaloz> @OpenWrt:/# wl gmode 6
<Kaloz> eth1: Invalid argument
<Kaloz> gmode   Set the 54g Mode (LegacyB|Auto||GOnly|BDeferred|Performance|LRS|Afterburner)
<Kaloz> but openwrt uses the afterburner drivers anyway :)
<oleg__> ok, try setting boardflags to 0x0388, commit changes and reload wl.o
<Kaloz> lol
<Kaloz> @OpenWrt:/# wl gmode 6
<Kaloz> @OpenWrt:/# wl gmode
<Kaloz> 54g Mode is 54g Afterburner (6)
<oleg__> cool.
<oleg__> afterburner demystified.

No utility required for bcm4712 devices.
