After quite a lot of CVS bisection, I've identified revision 1.24 of hw/pckbd.c ("QEMU keyboard issue with Gujin-2.2") to be responsible for the regression with the PS/2 mouse for FC4 guests.
With r1.24, I can read in the log of the kernel boot sequence : "PNP: PS/2 Controller [PNP0303:KBD,PNP0f13:MOU@ at 0x60,0x64 irq 1,12" Failed to disable AUX port, but continuing anyway... Is this a Sis? If AUX port is really absent please use the 'i8042.noaux' option. serio: i8042 KBD PORT at 0x60,0x64 irq 1" With r1.23, I only get : "PNP: PS/2 Controller [PNP0303:KBD,PNP0f13:MOU@ at 0x60,0x64 irq 1,12" serio: i8042 KBD PORT at 0x60,0x64 irq 1" Le Sunday 20 January 2008 21:58:05 Even Rouault, vous avez écrit : > Hi, > > I've tried QEMU 0.9.1 and PS/2 mouse support for FC4 guest seems to be > broken.
