90 | * @atomic_check: | |
91 | * | |
92 | * This is the only hook to validate an atomic modeset update. This | |
93 | * function must reject any modeset and state changes which the hardware | |
94 | * or driver doesn't support. This includes but is of course not limited | |
95 | * to: | |
96 | * | |
97 | * - Checking that the modes, framebuffers, scaling and placement | |
98 | * requirements and so on are within the limits of the hardware. | |
99 | * | |
100 | * - Checking that any hidden shared resources are not oversubscribed. | |
101 | * This can be shared PLLs, shared lanes, overall memory bandwidth, | |
102 | * display fifo space (where shared between planes or maybe even | |
103 | * CRTCs). | |
104 | * | |
105 | * - Checking that virtualized resources exported to userspace are not | |
106 | * oversubscribed. For various reasons it can make sense to expose | |
107 | * more planes, crtcs or encoders than which are physically there. One | |
108 | * example is dual-pipe operations (which generally should be hidden | |
109 | * from userspace if when lockstepped in hardware, exposed otherwise), | |
110 | * where a plane might need 1 hardware plane (if it's just on one | |
111 | * pipe), 2 hardware planes (when it spans both pipes) or maybe even | |
112 | * shared a hardware plane with a 2nd plane (if there's a compatible | |
113 | * plane requested on the area handled by the other pipe). | |
114 | * | |
115 | * - Check that any transitional state is possible and that if | |
116 | * requested, the update can indeed be done in the vblank period | |
117 | * without temporarily disabling some functions. | |
118 | * | |
119 | * - Check any other constraints the driver or hardware might have. | |
120 | * | |
121 | * - This callback also needs to correctly fill out the &drm_crtc_state | |
122 | * in this update to make sure that drm_atomic_crtc_needs_modeset() | |
123 | * reflects the nature of the possible update and returns true if and | |
124 | * only if the update cannot be applied without tearing within one | |
125 | * vblank on that CRTC. The core uses that information to reject | |
126 | * updates which require a full modeset (i.e. blanking the screen, or | |
127 | * at least pausing updates for a substantial amount of time) if | |
128 | * userspace has disallowed that in its request. | |
129 | * | |
130 | * - The driver also does not need to repeat basic input validation | |
131 | * like done for the corresponding legacy entry points. The core does | |
132 | * that before calling this hook. | |
133 | * | |
134 | * See the documentation of @atomic_commit for an exhaustive list of | |
135 | * error conditions which don't have to be checked at the | |
136 | * ->atomic_check() stage? | |

142 | * drm_atomic_helper_check(), or one of the exported sub-functions of | |
143 | * it. | |
144 | * | |
145 | * RETURNS: | |
146 | * | |
147 | * 0 on success or one of the below negative error codes: | |
148 | * | |
149 | * - -EINVAL, if any of the above constraints are violated. | |

151 | * - -EDEADLK, when returned from an attempt to acquire an additional | |
152 | * &drm_modeset_lock through drm_modeset_lock(). | |
153 | * | |
154 | * - -ENOMEM, if allocating additional state sub-structures failed due | |
155 | * to lack of memory. | |
156 | * | |
157 | * - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted. | |
158 | * This can either be due to a pending signal, or because the driver | |
159 | * needs to completely bail out to recover from an exceptional | |

167 | * @atomic_commit: | |
168 | * | |
169 | * This is the only hook to commit an atomic modeset update. The core | |
170 | * guarantees that @atomic_check has been called successfully before | |
171 | * calling this function, and that nothing has been changed in the | |
172 | * interim. | |
173 | * | |
174 | * See the documentation for struct &drm_atomic_state for how exactly | |
175 | * an atomic modeset update is described. | |
176 | * | |
177 | * Drivers using the atomic helpers can implement this hook using | |
178 | * drm_atomic_helper_commit(), or one of the exported sub-functions of | |
179 | * it. | |
180 | * | |
181 | * Nonblocking commits (as indicated with the nonblock parameter) must | |
182 | * do any preparatory work which might result in an unsuccessful commit | |
183 | * in the context of this callback. The only exceptions are hardware | |
184 | * errors resulting in -EIO. But even in that case the driver must | |
185 | * ensure that the display pipe is at least running, to avoid | |
186 | * compositors crashing when pageflips don't work. Anything else, | |
187 | * specifically committing the update to the hardware, should be done | |
188 | * without blocking the caller. For updates which do not require a | |
189 | * modeset this must be guaranteed. | |
190 | * | |
191 | * The driver must wait for any pending rendering to the new | |
192 | * framebuffers to complete before executing the flip. It should also | |
193 | * wait for any pending rendering from other drivers if the underlying | |
194 | * buffer is a shared dma-buf. Nonblocking commits must not wait for | |
195 | * rendering in the context of this callback. | |
196 | * | |
197 | * An application can request to be notified when the atomic commit has | |
198 | * completed. These events are per-CRTC and can be distinguished by the | |
199 | * CRTC index supplied in &drm_event to userspace. | |
200 | * | |
201 | * The drm core will supply a struct &drm_event in the event | |
202 | * member of each CRTC's &drm_crtc_state structure. See the | |
203 | * documentation for &drm_crtc_state for more details about the precise | |
204 | * semantics of this event. | |
205 | * | |
206 | * NOTE: | |
207 | * | |
208 | * Drivers are not allowed to shut down any display pipe successfully | |
209 | * enabled through an atomic commit on their own. Doing so can result in | |
210 | * compositors crashing if a page flip is suddenly rejected because the | |
211 | * pipe is off. | |
212 | * | |
213 | * RETURNS: | |
214 | * | |
215 | * 0 on success or one of the below negative error codes: | |
216 | * | |
217 | * - -EBUSY, if a nonblocking updated is requested and there is | |
218 | * an earlier updated pending. Drivers are allowed to support a queue | |
219 | * of outstanding updates, but currently no driver supports that. | |
220 | * Note that drivers must wait for preceding updates to complete if a | |
221 | * synchronous update is requested, they are not allowed to fail the | |
222 | * commit in that case. | |
223 | * | |
224 | * - -ENOMEM, if the driver failed to allocate memory. Specifically | |
225 | * this can happen when trying to pin framebuffers, which must only | |
226 | * be done when committing the state. | |
227 | * | |
228 | * - -ENOSPC, as a refinement of the more generic -ENOMEM to indicate | |
229 | * that the driver has run out of vram, iommu space or similar GPU | |
230 | * address space needed for framebuffer. | |
231 | * | |
232 | * - -EIO, if the hardware completely died. | |
233 | * | |
234 | * - -EINTR, -EAGAIN or -ERESTARTSYS, if the IOCTL should be restarted. | |
235 | * This can either be due to a pending signal, or because the driver | |
236 | * needs to completely bail out to recover from an exceptional | |
237 | * situation like a GPU hang. From a userspace point of view all errors are | |
238 | * treated equally. | |
239 | * | |
240 | * This list is exhaustive. Specifically this hook is not allowed to | |
241 | * return -EINVAL (any invalid requests should be caught in | |
