CardBus troubles with old BIOS went away with version 1.10 but heating probs now

DRI Works now after once AmiloA's BIOS is fixed see ACPI's DSDT & PCMCIA

Moving [[IRQ]]s in order to avoid conflicts when [[DRI]] is enabled

Thomas' irq assigning is OK, but concerning the DRI problem, it can be solved with less irq mixing.

It's strange, but I found that the BIG IRQ PROBLEM we all encountered when we wanted to start X with DRI is not what we thought it was.

Let me explain : we thought that the Radeon module tried to get IRQ #11, and that all modules present on the irq were disabled. That's not true.

The Radeon module takes the irq #10 by default.

But, IRQ #11 gets disabled because of the PCMCIA which is at LNKA

I don't know why but it's true

  • Test 1 : LNKA to irq #11 and Radeon (LNKC) to irq #10
  • Result : Start XWindow and IRQ #11 is disabled
  • Test 2 : LNKA to irq #3 and Radeon to irq #11
  • Result : Radeon should be happy, from what we knew… But it's not the case : irq #3 gets disabled ==========
  • Test 3 : LNKA to irq #11 and Radeon to irq #11, and also ALI on irq#11, and USB, and eth0 also ==========
  • Result : no IRQ problem at all === Everything works ===========
  • Test 3 : LNKA to irq #3 and Radeon to irq #3
  • Result : no problem === It works.===

Sam's conclusion :

Radeon goes where you want it to go ( IRQ #3, #5, #10, #11) without problems, as long as LNKA gets the same irq.

For instance :

Device (LNKA)  // @ http://rzr.online.fr/q/PCMCIA
...
// orig : IRQ (Level, ActiveLow, Shared) {11} // - ===rzr===
IRQ (Level, ActiveLow, Shared) {3} // + ===rzr===
Device (LNKC) // @ http://rzr.online.fr/q/Radeon , FireWire
...
// orig: //IRQ (Level, ActiveLow, Shared) {10} //- ===rzr===
IRQ (Level, ActiveLow, Shared) {3} //+ ===rzr===

<Slack_The_Skater>

i have a cirrus logic cl pcmcia bridge

and i need the i82365 module acoording to many forms and sites but when it try to load it, it dosen't load

says i might have incorrect irq paramters and such although the i82065 or w/e module loads

i am not sure of numbers all i know it has a 0 in it heh
