Shot in the dark (+ quick look into drivers/char/drm):
drivers/char/drm/radeon_irq.c: [...] irqreturn_t DRM(irq_handler)( DRM_IRQ_ARGS ) { drm_device_t *dev = (drm_device_t *) arg; drm_radeon_private_t *dev_priv = (drm_radeon_private_t *)dev->dev_private; u32 stat;
/* Only consider the bits we're interested in - others could be used * outside the DRM */ > stat = RADEON_READ(RADEON_GEN_INT_STATUS) > & (RADEON_SW_INT_TEST | RADEON_CRTC_VBLANK_STAT); > if (!stat) > return IRQ_NONE;
Can you turn the ">" lines into: stat = RADEON_READ(RADEON_GEN_INT_STATUS); if (!(stat & (RADEON_SW_INT_TEST | RADEON_CRTC_VBLANK_STAT))) { int ret = IRQ_NONE;
if (stat & ~(RADEON_SW_INT_TEST | RADEON_CRTC_VBLANK_STAT)) { DRM_INFO("Bingo !\n"); ret = IRQ_HANDLED; } return ret; }
If it does not work, please send complete dmesg and lspci -vx.
