The interrupts for EDID_READY or DDC_ERROR were never enabled in this driver, so reading EDID always timed out when chip was powered down and interrupts were used. Fix this and also remove clearing the interrupt flags, they are cleared in POWER_DOWN mode anyhow (unlike the interrupt enable flags) according to docs and my tests. Signed-off-by:

The drm_fbdev_cma_init function always calls the drm_helper_disable_unused_functions. Since it's part of the usual probe process, all the drivers using that helper will end up having their encoder and CRTC disable functions called at probe if their device has not been reported as enabled. This could be fixed by reading out from the registers the current state of the device if it is enabled, but even that will not handle the case where the device is actually disabled. Moreover, the drivers using the atomic modesetting expect that their enable and disable callback to be called when the device is already enabled or disabled (respectively). We can however fix this issue by moving the call to drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the drivers needing it (all the drivers calling drm_fbdev_cma_init and not using the atomic modesetting) explicitly call it.

When the framebuffer is a vmwgfx dma buffer and a proxy surface is created, the vmw_kms_update_proxy() function requires that the proxy surface width and the framebuffer pitch are compatible, otherwise display corruption occurs as seen in gnome-shell/native with software 3D. Since the framebuffer pitch is determined by user-space, allocate a proxy surface the width of which is based on the framebuffer pitch rather than on the framebuffer width.

An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.

According to documentation, A32 accesses are based on General State Base Address and bound checking is in place. Because size field (instruction State Base Address) limitation, it is not possible to address full 4GB memory region. A32 Stateless Model is used by some libraries and without this patch, the last page of 4GB address space is not accessible in 32bit processes. Reported-by:

This fixes reprobing of display connectors on resume. After some talking with danvet on IRC, I learned that calling drm_helper_hpd_irq_event() does actually trigger a full reprobe of each connector's status. It turns out this is the actual reason reprobing on resume hasn't been working (this was observed on a T440s): - We call hpd_init() - We check each connector for a couple of things before marking connector->polled with DRM_CONNECTOR_POLL_HPD, one of which is an active encoder. Of course, a disconnected port won't have an active encoder, so we don't add the flag to any of the connectors. - We call drm_helper_hpd_irq_event() - drm_helper_irq_event() checks each connector for the DRM_CONNECTOR_POLL_HPD flag. The only one that has it is eDP-1, so we skip reprobing each connector except that one. In addition, we also now avoid setting connector->polled to DRM_CONNECTOR_POLL_HPD for MST connectors, since their reprobing is handled by the mst helpers. This is probably what was originally intended to happen here. Changes since V1: * Use the explanation of the issue as the commit message instead * Change the title of the commit, since this does more then just stop a check for an encoder now * Add "Fixes" line for the patch that introduced this regression * Don't enable DRM_CONNECTOR_POLL_HPD for mst connectors Changes since V2: * Put patch changelog above Signed-off-by * Follow Daniel Vetter's suggestion for making the code here a bit more legible Fixes: 0e32b39c ("drm/i915: add DP 1.2 MST support (v0.7)") Cc: stable@vger.kernel.org Signed-off-by:

Following a GPU reset, we may leave the context in a poorly defined state, and reloading from that context will leave the GPU flummoxed. For secondary contexts, this will lead to that context being banned - but currently it is also causing the default context to become banned, leading to turmoil in the shared state.

This patch fixes a kernel panic issue which happened when drm driver is closed while modetest. This issue could be reproduced easily by launching modetest with page flip repeatedly. The reason is that invalid drm_file object could be accessed by send_vblank_event function when finishing page flip if the drm_file object was removed by drm_release and there was a pended page flip event which was already committed to hardware. So this patch makes the pended page flip event to be cancelled by preclose callback which is called at front of drm_release function. Changelog v2: - free vblank event objects belonging to the request process, increment event space and decrease pending_update when cancelling the event Signed-off-by:
