130 /* We have to use 4 textures here.
131 *
132 * 1. iDrawTex - the texture clients can draw to and then submit it for contents acquisition via crServerRpwEntrySubmit
133 * 2. iSubmittedTex - the texture submitted to the worker for processing and, whose processing has not start yet,
134 * i.e. it is being in the queue and can be safely removed/replaced [from] there
135 * 3. iWorkerTex - the texture being prepared & passed by the worker to the GPU (stage 1 of a worker contents acquisition process)
136 * 4. iGpuTex - the texture passed/processed to/by the GPU, whose data is then acquired by the server (stage 2 of a worker contents acquisition process)
137 *
138 * - There can be valid distinct iGpuTex, iWorkerTex, iSubmittedTex and iDrawTex present simultaneously.
139 * - Either or both of iSubmittedTex and iFreeTex are always valid
140 *
141 * Detail:
142 *
143 * - iSubmittedTex and iFreeTex modifications are performed under CR_SERVER_RPW::CritSect lock.
144 *
145 * - iDrawTex can only be changed by client side (i.e. the crServerRpwEntrySubmit caller), this is why client thread can access it w/o a lock
146 * - iSubmittedTex and iFreeTex can be modified by both client and worker, so lock is always required
147 *
148 * - iDrawTex can be accessed by client code only
149 * - iWorkerTex and iGpuTex can be accessed by worker code only
150 * - iSubmittedTex and iFreeTex can be accessed under CR_SERVER_RPW::CritSect lock only
151 * - either or both of iSubmittedTex and iFreeTex are always valid (see below for more explanation),
152 * this is why client can easily determine the new iDrawTex value on Submit, i.e. :
153 *
154 * (if initial iSubmittedTex was valid)
155 * ---------------
156 * | ^
157 * > |
158 * Submit-> iDrawTex -> iSubmittedTex
159 * ^
160 * | (if initial iSubmittedTex was NOT valid)
161 * iFreeTex
162 *
163 * - The worker can invalidate the iSubmittedTex (i.e. do iSubmittedTex -> iWorkerTex) only after it is done
164 * with the last iWorkerTex -> iGpuTex transformation freeing the previously used iGpuTex to iFreeTex.
165 *
166 * - A simplified worker iXxxTex transformation logic is:
167 * 1. iFreeTex is initially valid
168 * 2. iSubmittedTex -> iWorkerTex;
169 * 3. submit iWorkerTex acquire request to the GPU
170 * 4. complete current iGpuTex
171 * 5. iGpuTex -> iFreeTex
172 * 6. iWorkerTex -> iGpuTex
173 * 7. goto 1

566/* We moved all CrHgsmi command processing to crserverlib to keep the logic of dealing with CrHgsmi commands in one place.
567 *
568 * For now we need the notion of CrHgdmi commands in the crserver_lib to be able to complete it asynchronously once it is really processed.
569 * This help avoiding the "blocked-client" issues. The client is blocked if another client is doing begin-end stuff.
570 * For now we eliminated polling that could occur on block, which caused a higher-priority thread (in guest) polling for the blocked command complition
571 * to block the lower-priority thread trying to complete the blocking command.
572 * And removed extra memcpy done on blocked command arrival.
573 *
574 * In the future we will extend CrHgsmi functionality to maintain texture data directly in CrHgsmi allocation to avoid extra memcpy-ing with PBO,
575 * implement command completion and stuff necessary for GPU scheduling to work properly for WDDM Windows guests, etc.
576 *
577 * NOTE: it is ALWAYS responsibility of the crVBoxServerCrHgsmiCmd to complete the command!
