2017-03-27drm: bochs: Prevent double-free of fb helperGabriel Krisman Bertazi1-1/+3
If fbdev registration fails for whatever reason, the error path of bochs_fbdev_init() will call bochs_fbdev_fini(), but since an fbdev initialization error is not fatal to the probe function, a subsequent device removal will try to call bochs_fbdev_fini() again, hitting the Oops below. This was detected by 0-day with a failing framebuffer registration and CONFIG_DEBUG_TEST_DRIVER_REMOVE=y. This reproduces the scenario I mentioned above at insmod time, because the test attempts to remove the device right after probing. root@debian:~# insmod bochs-drm.ko [ 17.609635] [drm] Found bochs VGA, ID 0xb0c0.

2017-03-27drm/atomic: Introduce drm_atomic_helper_shutdownDaniel Vetter6-25/+57
The trouble here is that it does multiple atomic commits under one drm_modeset_lock_all, which breaks the behind-the-scenes acquire context magic that function pulls off. It's much better to have one overall atomic commit. That we still have multiple atomic commits prevents us from adding some pretty useful debug checks to the atomic machinery. Hence it is really a bad idea to call the legacy drm_crtc_force_disable_all() function. There's 2 atomic drivers using this still, nouveau and tinydrm. To fix this, introduce a new drm_atomic_helper_shutdown() by extracting the code from i915. While at it improve kernel-doc and catch future offenders by sprinkling a WARN_ON into the legacy function. We should probably move those into the legacy modeset helpers, too ... v2: Make it compile on arm drivers too (Noralf). v3: Correct kerneldoc to point at _disable_all().

2017-03-27drm: dw_hdmi: Don't rely on the status of the bridge for updating HPDRomain Perier1-1/+1
Currently, the irq handler that monitors changes for HPD and RX_SENSE relies on the status of the bridge for updating the status of the HPD. The update is done only when the bridge is enabled. However, on Rockchip platforms we have found use cases where it could be a problem. When HDMI is being used, turning off/on the screen or unplugging/re-plugging the cable, the following simplified code path will happen: - dw_hdmi_irq() will be triggered by an HPD event, as the bridge is on hdmi->disabled is false, then the handler will update the rxsense flag accordingly. - dw_hdmi_update_power() will be invoked with the mode DRM_FORCE_UNSPECIFIED and rxsense == 1, so dw_hdmi_poweroff() will be called and the PHY will be desactivated (its pixel clocks and TMDS) [...] - dw_hdmi_bridge_disable() will be invoked, the bridge will be marked as disabled. - dw_hdmi_irq() will be triggered by an HPD event, as the bridge is currently disabled the HPD status won't be updated, so hdmi->rxsense won't be changed. Even if the data part of the PHY is disabled, this information coming from the HDMI Transmitter is correct and should be saved. [...] - dw_hdmi_bridge_enable() will be invoked, the bridge will be marked as enabled. - dw_hdmi_update_power() will be called. When hdmi->force is equal to DRM_FORCE_UNSPECIFIED the function will rely on hdmi->rxsense. If this field has not been updated by the irq handler, it will be false and DRM_FORCE_ON won't be put to hdmi->force. Consequently, most of the time dw_hdmi_poweron() won't be called in this use case, TMDS won't be re-enabled the PHY won't be re-initialized, resulting in a "Signal not found". This commit fixes the issue by removing the check for "!hdmi->disabled". As already explained, even if the PHY is partially disabled, information coming from HDMI Transmitter about HPD should be saved for a later use.

2017-03-22drm/dp: Split drm_dp_mst_allocate_vcpiPandiyan, Dhinakaran5-16/+19
drm_dp_mst_allocate_vcpi() apart from setting up the vcpi structure, also finds if there are enough slots available. This check is a duplicate of that implemented in drm_dp_mst_find_vcpi_slots(). Let's move this check out and reuse the existing drm_dp_mst_find_vcpi_slots() function to check if there are enough vcpi slots before allocating them. This brings the check to one place. Additionally drivers that will use MST state tracking for atomic modesets can use the atomic version of find_vcpi_slots() and reuse drm_dp_mst_allocate_vcpi() Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1489648231-30700-4-git-send-email-dhinakaran.pandiyan@intel.com
