From 190a43783f2c43186180c827444d4eac901b4bcf Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Thu, 17 Jun 2010 12:42:14 +0200 Subject: [PATCH] drm/nouveau: Don't clear AGPCMD completely on INIT_RESET. We just need to clear the SBA and ENABLE bits to reset the AGP controller: If the AGP bridge was configured to use "fast writes", clearing the FW bit would break the subsequent MMIO writes and eventually end with a lockup. Note that all the BIOSes I've seen do the same as we did (it works for them because they don't use MMIO), OTOH the blob leaves FW untouched.
