From 1c98b4871cca4b7ce07e19f92f934d47cf7210b0 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Mon, 13 May 2013 18:12:25 -0300 Subject: [PATCH 01/22] drm/i915: Adding more reserved PCI IDs for Haswell. At DDX commit Chris mentioned the tendency we have of finding out more PCI IDs only when users report. So Let's add all new reserved Haswell IDs. This patch also fix GT3 names. I'no not sending in separated patche because names are only in few comments and not in variable names. v2: Fix some mobile ids (by Paulo) References: http://bugs.freedesktop.org/show_bug.cgi?id=63701 Cc: Chris Wilson Cc: Paulo Zanoni Signed-off-by: Rodrigo Vivi Cc: stable@vger.kernel.org Reviewed-by: Paulo Zanoni Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.c | 46 +++++++++++++++++++++++++-------- 1 file changed, 35 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 9ebe895c17d6b..a2e4953b8e8d5 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -364,40 +364,64 @@ static const struct pci_device_id pciidlist[] = { /* aka */ INTEL_VGA_DEVICE(0x016a, &intel_ivybridge_d_info), /* GT2 server */ INTEL_VGA_DEVICE(0x0402, &intel_haswell_d_info), /* GT1 desktop */ INTEL_VGA_DEVICE(0x0412, &intel_haswell_d_info), /* GT2 desktop */ -

This wasn't enforced though if only the FB changed, everything else (format, connector etc.) remaining the same. In this case we only set the new FB base and left the connector in the old power save mode. Fix this by forcing a full modeset whenever there is an attached FB and any affected connector is in a power save mode. V_2: Run the test for encoders in power save mode outside the the test for fb change: user space may have just disabled the encoders but left everything else in place. Make sure the connector list is not empty before running this test.
