From 3f22c0966dcc26b3a8310afd8baa238ab857b611 Mon Sep 17 00:00:00 2001 From: Nicolai Haehnle Date: Fri, 18 Feb 2005 18:57:38 +0000 Subject: [PATCH] r300RefillCurrentDmaRegion: Retry buffer acquisition only once, after waiting for the engine to idle. There's no way for another buffer to become free anyway once the engine is idle. --- src/mesa/drivers/dri/r300/r300_ioctl.c | 19 ++++++++++++------- 1 file changed, 12 insertions(+), 7 deletions(-) diff --git a/src/mesa/drivers/dri/r300/r300_ioctl.c b/src/mesa/drivers/dri/r300/r300_ioctl.c index e8e044e..de21bfc 100644 --- a/src/mesa/drivers/dri/r300/r300_ioctl.c +++ b/src/mesa/drivers/dri/r300/r300_ioctl.c @@ -403,19 +403,24 @@ void r300RefillCurrentDmaRegion(r300ContextPtr rmesa) LOCK_HARDWARE(&rmesa->radeon); /* no need to validate */ - while (1) { - ret = drmDMA(fd, &dma); - if (ret == 0) - break; + ret = drmDMA(fd, &dma); + if (ret != 0) { + /* Try to release some buffers and wait until we can't get any more */ if (rmesa->dma.nr_released_bufs) { r300FlushCmdBufLocked(rmesa, __FUNCTION__); } - if (rmesa->radeon.do_usleeps) { + if (RADEON_DEBUG & DEBUG_DMA) + fprintf(stderr, "Waiting for buffers\n"); + + radeonWaitForIdleLocked(&rmesa->radeon); + ret = drmDMA(fd, &dma); + + if (ret != 0) { UNLOCK_HARDWARE(&rmesa->radeon); - DO_USLEEP(1); - LOCK_HARDWARE(&rmesa->radeon); + fprintf(stderr, "Error: Could not get dma buffer... exiting\n"); + exit(-1); } } -- 2.7.4
