<p>This document presents know-how on the MHI protocol.</p>
<div>
<h2 id="10">Preview¶</h2>
<p>MHI is a well developed protocol by Qualcomm Innovation Center, Inc.<br/>
With the ability to control processors and communicate through high-speed modern devices<br/>
A fast device with a shared memory bus. Although MHI can be configured<br/>
For any school, peripherals are mainly used among PCIe based devices. IMC<br/>
provides logical waterways on the physical provides and bus transport<br/>
Modem protocols such as Webmondo control messages, IP data packets, and<br/>
Diagnostics covering at least one of these types of logical channels. Also OMC<br/>
The protocol has a data acknowledgment function and manages that this is a power state<br/>
Modems and/or other logical channel. Internals¶</h2>
<div>
<h3 id="11">MMIO¶</h3>
<p>MMIO</p>
</div>
<div>
<h2>mhi (Memory Mapped IO) consists of a set of hardware registers,<br/>
which are mapped from the peripheral bus space to the host callback similar to PCIe.<br/>
Here are the main components of the MMIO register space:</p>
<p>MHI access logs: control to MHI configuration registers</p>
<p>MHI BHI Logs: The BHI (boot host interface) registers are actually used by the host.<br/>
upload someone’s firmware to before device initialization MHI.Channel </p>
<p>doorbell array: doorbell channel registers, (db) used by host<br/>
Notify the device when there are almost certainly new tasks to perform.</p>
<p>Event doorbell array: Doorbell register connected to the event context array<br/>
(db) are used by some hosts for current events notification device<br/>
available.debug: </p>
<p>Register The register defined below and the counters used to grant access to the device.<br/>
A container for debugging information, such as the stability of features appropriate for the host.</p>
</div>
<div>
<h3>Data structure structures¶</h3>
<p>All data shared by MHI, reside in the memory of the main host system. Usage<br/>
physical interface, the element accesses these data structures. MHI others and data<br/>
Structures Data buffers are provided in memory areas of the learning host.<br/>
device.</p>
<p>Channel Array: A context arranges all the channel controls that are in a data channel.<br/>
Context table.</p>
<p>Broadcast rings: used by the host to schedule work items. in<br/>
Transmission rings are how a complete circular queue of descriptors (TD) is organized.</p>
<p>Event context array: All event configurations are neatly organized.<br/>
Data array event context.</p>
<p>Event tones: used by the device so that you can send completion messages about actions and state transitions.<br/>
host</p>
<p>Command context All tables: keep control of configurations organized in a team<br/>
Table of contextual documents.</p>
<p>Command ringtones: used by the host or host to send MHI commands to the device. Are these orders organized?<br/>
ringing like a cyclic command queuedescriptor (CD).</p>
</div>
<div>
<h3 id="13">Lines¶</h3>
<p>MHI links are logical one-way data links between host, device, and critical devices.<br/>
The concept in mhi channels is similar to USB.MHI endpoints supported by 256 for<br/>
with channels. However, individual device implementations can support as much as possible<br/>
the smallest number of threads allowed.</p>
<p>Two unidirectional channels with their associated cable trays form<br/>
bidirectional line, data that unfortunately can be used by higher level protocols<br/>
transport application data boxes (such as IP packets, control cable box messages,<br/>
diagnostic messages, etc.). Each is linked to One mode to only<br/>
Transfer ring.</p>
</div>
<div>
<h3 id="14">Transmission Rings¶</h3>
<p>Data transfer between the host and the device is organized in accordance with certain rules.<br/>
Transmission descriptor (TD) channels. in fact td are controlled by transmission rings.<br/>
defines each channel’s relationship between device scope and host<br/>
Reminder. TD consist of or one severaltheir ring elements (or transmission units):</p>
<div>
<div>
<pre>[reading pointer (RP)]----------->[ring element] } TD
[Record Pointer (WP)]-[Ring Element]
- [Ring Element]
--------->[ring element]
element]
</pre>
</div>
</div>
<p>Below [Ring are the main ways to use compression rings:</p>
<p><str></p>
<li>
<p>The host allocates space to store the broadcast ringtone.</p>
</li>
<li>
<p>The host bed sets the underlying read pointer, the pointer, without forgetting the corresponding write pointer<br/>
String context.</p>
</li>
<li>
<p>A ring can be considered empty if == rp WP.Est </p>
</li>
<li>
<p>Ring is full +wp when 1 == RP.Specifiers</p>
</li>
<li>
<p>rp after the element to serve my device.</p>
</li>
<li>
<p>If the host has a new buffer to send, it updates the element with a stripe<br/>
Buffer info, my WP increments to next element and matrix bus<br/>
Linked channel comics.</p>
</li>
</ul>
</div>
<div>
<h3 id="15">Event Ringtones¶</h3>
<p>Node-to-device events can be organized into loop events and defined by a specific event.<br/>
Descriptors (ED). Event ringtones are used bydevice for notification of natural disasters, such as<br/>
Data transfer completion status, instruction completion status, status and changes<br/>
master. Are there multiple EDs located on the host?<br/>
memory for o. EDs consist of one or more ring elements (or transmission pointer blocks):</p>
<div>
<div>
<pre>[Read(RP)]----------->[Ring element] } ED
[Record Pointer (WP)]-[Ring Element]
1) [ring element]
--------->[ring element]
[ring element]
</pre>
</div>
</div>
<p>The main uses of alliances are shown below:</p>
<p><str></p>
<li>
<p>The host allocates memory for the ringtone.</p>
</li>
<li>
<p>The base host sets the read pointer, the peak write pointer, and the corresponding pointer.<br/>
String context.</p>
</li>
<li>
<p>Number and device have a copy of the local RP, WP.</p>
</li>
<li>
<p>Ringtone is considered empty (no event to show), WP + RP 1 ==.</p>
</li>
<li>
<p>A ring is considered more complete than an event when RP == WP.</p>
</li>
<li>
<p>When there is a new event that the device has to offer, it updates the ED.<br/>
points per rp RP increments, to the additional element And fires, which<br/>
interrupt.element¶</h3>
<p></p>
<p>Element</p>

<h3>Circular is a circular data structure for transferring one block.<br/>
relationship between and host device A. Types of Source Ring Transfer Elements<br/>
singles are pointers to the buffer, current buffer size and additional control<br/>
Information. Other non-audio element types may only contain a handle and a state.<br/>
Information. For single-buffer processes, the descriptor ring consists of<br/>
one item. For large multi-buffer operations (e.g. spread and collect)<br/>
Elements can certainly be combined to form much more time descriptors.</p>
