Could ever GMA 500 work with realtime kernel?

[maddis]

Hi,

I'm having exact same problem with Ubuntu 10.04 with rt-kernel (2.6.31-11). I tried to patch the psb_drv.c as suggested, but changing the line:

dev_priv->irqmask_lock = SPIN_LOCK_UNLOCKED;

to

dev_priv->irqmask_lock=__SPIN_LOCK_UNLOCKED(old_style_spin_int);

Did not solve anything. I still get the same error as before. I looked from spinlock_types.h for the __SPIN_LOCK_UNLOCKED - definition and I cannot see what's the problem.

Has someone been able to compile psb-driver to rt-kernel with spin_locks?

2 yeras since last post, is there any hope for GM500 and realtime kernel?

I've tried this method and all I got is a blank screen after trying boot the RT kernel.

I've got Ubuntu 11.04 on my Acer AO751H with GMA 500, and that may be the last version I ever install on it. 11.04 has a few issues but still works reasonably well. Too bad 11.04 is no longer supported! I'll probably put XP back on it and sell it, because I'm tired of all the hassles I've had with this chipset and Linux. It's an old/slow netbook now anyway - time to buy something else.
