+ * In the olden days the SET/DROP_MASTER ioctls used to return EACCES when
+ * CAP_SYS_ADMIN was not set. This was used to prevent rogue applications
+ * from becoming master and/or failing to release it.
+ *
+ * At the same time, the first client (for a given VT) is _always_ master.
+ * Thus in order for the ioctls to succeed, one had to _explicitly_ run the
+ * application as root or flip the setuid bit.
+ *
+ * If the CAP_SYS_ADMIN was missing, no other client could become master...
+ * EVER :-( Leading to a) the graphics session dying badly or b) a completely
+ * locked session.
+ *
+ *
+ * As some point systemd-logind was introduced to orchestrate and delegate
+ * master as applicable. It does so by opening the fd and passing it to users
+ * while in itself logind a) does the set/drop master per users' request and
+ * b) * implicitly drops master on VT switch.
+ *
+ * Even though logind looks like the future, there are a few issues:
+ * - some platforms don't have equivalent (Android, CrOS, some BSDs) so
+ * root is required _solely_ for SET/DROP MASTER.
+ * - applications may not be updated to use it,
+ * - any client which fails to drop master* can DoS the application using
+ * logind, to a varying degree.
+ *
+ * * Either due missing CAP_SYS_ADMIN or simply not calling DROP_MASTER.
+ *
+ *
+ * Here we implement the next best thing:
+ * - ensure the logind style of fd passing works unchanged, and
+ * - allow a client to drop/set master, iff it is/was master at a given point
+ * in time.
+ *
+ * Note: DROP_MASTER cannot be free for all, as an arbitrator user could:
+ * - DoS/crash the arbitrator - details would be implementation specific
+ * - open the node, become master implicitly and cause issues
+ *
+ * As a result this fixes the following when using root-less build w/o logind
+ * - startx
+ * - weston
+ * - various compositors based on wlroots

- * This library provides a GEM buffer object that is backed by video RAM
- * (VRAM). It can be used for framebuffer devices with dedicated memory.
+ * This library provides &struct drm_gem_vram_object (GEM VRAM), a GEM
+ * buffer object that is backed by video RAM (VRAM). It can be used for
+ * framebuffer devices with dedicated memory.
*
* The data structure &struct drm_vram_mm and its helpers implement a memory
- * manager for simple framebuffer devices with dedicated video memory. Buffer
- * objects are either placed in video RAM or evicted to system memory. The rsp.
- * buffer object is provided by &struct drm_gem_vram_object.
+ * manager for simple framebuffer devices with dedicated video memory. GEM
+ * VRAM buffer objects are either placed in the video memory or remain evicted
+ * to system memory.
+ *
+ * With the GEM interface userspace applications create, manage and destroy
+ * graphics buffers, such as an on-screen framebuffer. GEM does not provide
+ * an implementation of these interfaces. It's up to the DRM driver to
+ * provide an implementation that suits the hardware. If the hardware device
+ * contains dedicated video memory, the DRM driver can use the VRAM helper
+ * library. Each active buffer object is stored in video RAM. Active
+ * buffer are used for drawing the current frame, typically something like
+ * the frame's scanout buffer or the cursor image. If there's no more space
+ * left in VRAM, inactive GEM objects can be moved to system memory.
+ *
+ * The easiest way to use the VRAM helper library is to call
+ * drm_vram_helper_alloc_mm(). The function allocates and initializes an
+ * instance of &struct drm_vram_mm in &struct drm_device.vram_mm . Use
+ * &DRM_GEM_VRAM_DRIVER to initialize &struct drm_driver and
+ * &DRM_VRAM_MM_FILE_OPERATIONS to initialize &struct file_operations;
+ * as illustrated below.
+ *
+ * .. code-block:: c
+ *
+ * struct file_operations fops ={
+ * .owner = THIS_MODULE,
+ * DRM_VRAM_MM_FILE_OPERATION
+ * };
+ * struct drm_driver drv = {
+ * .driver_feature = DRM_ ... ,
+ * .fops = &fops,
+ * DRM_GEM_VRAM_DRIVER
+ * };
+ *
+ * int init_drm_driver()
+ * {
+ * struct drm_device *dev;
+ * uint64_t vram_base;
+ * unsigned long vram_size;
+ * int ret;
+ *
+ * // setup device, vram base and size
+ * // ...
+ *
+ * ret = drm_vram_helper_alloc_mm(dev, vram_base, vram_size);
+ * if (ret)
+ * return ret;
+ * return 0;
+ * }
+ *
+ * This creates an instance of &struct drm_vram_mm, exports DRM userspace
+ * interfaces for GEM buffer management and initializes file operations to
+ * allow for accessing created GEM buffers. With this setup, the DRM driver
+ * manages an area of video RAM with VRAM MM and provides GEM VRAM objects
+ * to userspace.
+ *
+ * To clean up the VRAM memory management, call drm_vram_helper_release_mm()
+ * in the driver's clean-up code.
+ *
+ * .. code-block:: c
+ *
+ * void fini_drm_driver()
+ * {
+ * struct drm_device *dev = ...;
+ *
+ * drm_vram_helper_release_mm(dev);
+ * }
+ *
+ * For drawing or scanout operations, buffer object have to be pinned in video
+ * RAM. Call drm_gem_vram_pin() with &DRM_GEM_VRAM_PL_FLAG_VRAM or
+ * &DRM_GEM_VRAM_PL_FLAG_SYSTEM to pin a buffer object in video RAM or system
+ * memory. Call drm_gem_vram_unpin() to release the pinned object afterwards.
+ *
+ * A buffer object that is pinned in video RAM has a fixed address within that
+ * memory region. Call drm_gem_vram_offset() to retrieve this value. Typically
+ * it's used to program the hardware's scanout engine for framebuffers, set
+ * the cursor overlay's image for a mouse cursor, or use it as input to the
+ * hardware's draing engine.
+ *
+ * To access a buffer object's memory from the DRM driver, call
+ * drm_gem_vram_kmap(). It (optionally) maps the buffer into kernel address
+ * space and returns the memory address. Use drm_gem_vram_kunmap() to
+ * release the mapping.

+ * From the computer's perspective, every time the monitor displays
+ * a new frame the scanout engine has "scanned out" the display image
+ * from top to bottom, one row of pixels at a time. The current row
+ * of pixels is referred to as the current scanline.
+ *
+ * In addition to the display's visible area, there's usually a couple of
+ * extra scanlines which aren't actually displayed on the screen.
+ * These extra scanlines don't contain image data and are occasionally used
+ * for features like audio and infoframes. The region made up of these
+ * scanlines is referred to as the vertical blanking region, or vblank for
+ * short.
+ *
+ * For historical reference, the vertical blanking period was designed to
+ * give the electron gun (on CRTs) enough time to move back to the top of
+ * the screen to start scanning out the next frame. Similar for horizontal
+ * blanking periods. They were designed to give the electron gun enough
+ * time to move back to the other side of the screen to start scanning the
+ * next scanline.

+ * On a lot of display hardware, programming needs to take effect during the

+ * any visual artifacts on the screen. In some unforgiving hardware, some of
+ * this programming has to both start and end in the same vblank. To help
+ * with the timing of the hardware programming, an interrupt is usually
+ * available to notify the driver when it can start the updating of registers.
+ * The interrupt is in this context named the vblank interrupt.
+ *
+ * The vblank interrupt may be fired at different points depending on the
+ * hardware. Some hardware implementations will fire the interrupt when the
+ * new frame start, other implementations will fire the interrupt at different
+ * points in time.

-/**
- * DOC: overview
- *
- * This library provides &struct drm_gem_vram_object (GEM VRAM), a GEM
- * buffer object that is backed by video RAM. It can be used for
- * framebuffer devices with dedicated memory. The video RAM is managed
- * by &struct drm_vram_mm (VRAM MM).
- *
- * With the GEM interface userspace applications create, manage and destroy
- * graphics buffers, such as an on-screen framebuffer. GEM does not provide
- * an implementation of these interfaces. It's up to the DRM driver to
- * provide an implementation that suits the hardware. If the hardware device
- * contains dedicated video memory, the DRM driver can use the VRAM helper
- * library. Each active buffer object is stored in video RAM. Active
- * buffer are used for drawing the current frame, typically something like
- * the frame's scanout buffer or the cursor image. If there's no more space
- * left in VRAM, inactive GEM objects can be moved to system memory.
- *
- * The easiest way to use the VRAM helper library is to call
- * drm_vram_helper_alloc_mm(). The function allocates and initializes an
- * instance of &struct drm_vram_mm in &struct drm_device.vram_mm . Use
- * &DRM_GEM_VRAM_DRIVER to initialize &struct drm_driver and
- * &DRM_VRAM_MM_FILE_OPERATIONS to initialize &struct file_operations;
- * as illustrated below.
- *
- * .. code-block:: c
- *
- * struct file_operations fops ={
- * .owner = THIS_MODULE,
- * DRM_VRAM_MM_FILE_OPERATION
- * };
- * struct drm_driver drv = {
- * .driver_feature = DRM_ ... ,
- * .fops = &fops,
- * DRM_GEM_VRAM_DRIVER
- * };
- *
- * int init_drm_driver()
- * {
- * struct drm_device *dev;
- * uint64_t vram_base;
- * unsigned long vram_size;
- * int ret;
- *
- * // setup device, vram base and size
- * // ...
- *
- * ret = drm_vram_helper_alloc_mm(dev, vram_base, vram_size);
- * if (ret)
- * return ret;
- * return 0;
- * }
- *
- * This creates an instance of &struct drm_vram_mm, exports DRM userspace
- * interfaces for GEM buffer management and initializes file operations to
- * allow for accessing created GEM buffers. With this setup, the DRM driver
- * manages an area of video RAM with VRAM MM and provides GEM VRAM objects
- * to userspace.
- *
- * To clean up the VRAM memory management, call drm_vram_helper_release_mm()
- * in the driver's clean-up code.
- *
- * .. code-block:: c
- *
- * void fini_drm_driver()
- * {
- * struct drm_device *dev = ...;
- *
- * drm_vram_helper_release_mm(dev);
- * }
- *
- * For drawing or scanout operations, buffer object have to be pinned in video
- * RAM. Call drm_gem_vram_pin() with &DRM_GEM_VRAM_PL_FLAG_VRAM or
- * &DRM_GEM_VRAM_PL_FLAG_SYSTEM to pin a buffer object in video RAM or system
- * memory. Call drm_gem_vram_unpin() to release the pinned object afterwards.
- *
- * A buffer object that is pinned in video RAM has a fixed address within that
- * memory region. Call drm_gem_vram_offset() to retrieve this value. Typically
- * it's used to program the hardware's scanout engine for framebuffers, set
- * the cursor overlay's image for a mouse cursor, or use it as input to the
- * hardware's draing engine.
