From 8f50614910c40366d94964fe2c5da5772aff2f96 Mon Sep 17 00:00:00 2001 From: Axel Davy Date: Sat, 10 Jan 2015 18:49:16 +0100 Subject: [PATCH] gallium/targets/d3dadapter9: Fix device detection for render-nodes When on a render node the unique ioctl doesn't work. This patch drops the code to detect the device, which relied on an ioctl, and replaces it by the mesa loader function. The mesa loader function is more complete and won't fail for render-nodes. Alternatively we could also have used the pipe cap to determine the vendor and device id from the driver.
