Without this, we will get a dmesg-warn when enable_fbc is cleared on a fastset: WARN_ON(!crtc_state->enable_fbc) WARNING: CPU: 0 PID: 1090 at drivers/gpu/drm/i915/intel_fbc.c:1091 intel_fbc_enable+0x2ce/0x580 [i915] RIP: 0010:intel_fbc_enable+0x2ce/0x580 [i915] Call Trace: ? __mutex_unlock_slowpath+0x46/0x2b0 intel_update_crtc+0x6f/0x2b0 [i915] skl_update_crtcs+0x1d1/0x2b0 [i915] intel_atomic_commit_tail+0x1ea/0xdb0 [i915] intel_atomic_commit+0x244/0x330 [i915] drm_mode_atomic_ioctl+0x85d/0x950 ? drm_atomic_set_property+0x970/0x970 drm_ioctl_kernel+0x81/0xf0 drm_ioctl+0x2de/0x390 ? drm_atomic_set_property+0x970/0x970 ? __handle_mm_fault+0x81b/0xfc0 do_vfs_ioctl+0xa0/0x6e0 ? __do_page_fault+0x2a5/0x550 ksys_ioctl+0x35/0x60 __x64_sys_ioctl+0x11/0x20 do_syscall_64+0x55/0x190 entry_SYSCALL_64_after_hwframe+0x49/0xbe Changes since v1: - Move intel_fbc_disable to intel_update_crtc() (Hans) Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181220151719.30586-1-maarten.lankhorst@linux.intel.com Reviewed-by: Hans de Goede <hdegoede@redhat.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
