<h2 id="products">Products</h2> <h3>Linux</h3> <p>May 12, 2009, MontaVista announced MontaVista Linux 6 (MVL6) comprising Market Specific Distributions, MontaVista Integration Platform, Software Development Kit, MontaVista Zone Content Server, and support and services. There are several differences between MVL6 and prior MontaVista Linux products. The main ones are: </p> <ul><li>Market Specific Distributions (MSD) – Linux operating systems (<a href="/facts/Kernel_(operating_system)/uEj4U3Rz">kernel</a> + <a href="/facts/Userland_(computing)/0yIzMY8t">userland</a>) optimized for each specific semiconductor vendor's hardware.</li> <li>MontaVista Integration Platform – based on <a href="/facts/BitBake/bhvczl11">BitBake</a>, analogous to <i><a href="/facts/Make_(software)/5q1DQ4ot">make</a></i>, which analyzes a set of directives and then builds a task dependency tree to satisfy a user command. BitBake then executes the defined tasks to completion.</li> <li>MontaVista Zone Content Server – accessed from behind a <a href="/facts/Proxy_server/ArhwQE74">proxy server</a>, or local <a href="/facts/Web_mirror/n9mBsW8j">web mirror</a> for offline operations, to fetch software and updates. Rather than depending on a mix of public <a href="/facts/HTTP/TWtvf7JD">HTTP</a>, <a href="/facts/Concurrent_Versions_System/PKnqSra2">Concurrent Versions System</a> (CVS), <a href="/facts/Git_(software)/U5Ty9QmQ">Git</a>, and <a href="/facts/Subversion_(software)/b5j9wAbt">Subversion</a> servers across the Internet, there is one source for each original source <a href="/facts/File_archiver/ER6mjCCy">archive</a> and <a href="/facts/Patch_(computing)/sIHVBPls">patch</a>.</li></ul> <p><i>MontaVista Linux</i> (formerly named <i>Hard Hat Linux</i>) is a <a href="/facts/Linux_distribution/0vVl4N4f">Linux distribution</a> that has been enhanced to become a full <a href="/facts/Real-time_operating_system/IvUCFwCL">real-time operating system</a>. The work on real-time performance has since continued to a point where MontaVista claims to support <a href="/facts/Hard_real-time/p9HxgL4L">hard real-time</a> tasks on embedded Linux as of MontaVista Linux 4.0, with response times as fast as other real-time operating systems.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p><p>MontaVista sells <i>subscriptions</i>, which consist of software, <a href="/facts/Software_documentation/cSXDUPPg">documentation</a>, and <a href="/facts/Technical_support/8xL4yzMY">technical support</a>. The software includes a <a href="/facts/Linux_kernel/dlkduHuA">Linux kernel</a> and <a href="/facts/Toolchain/SmlWCJhY">toolchain</a> aimed at a specific hardware configuration, collectively called a <a href="/facts/Board_support_package/dgKtK8DP">Linux Support Package</a> (LSP), and other integrated tools including the <a href="/facts/Eclipse_(software)/YoqHVjas">Eclipse</a>-based DevRocket <a href="/facts/Integrated_development_environment/jbEINSQf">integrated development environment</a> (IDE).<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> The distribution is available in three editions, each aimed at different <a href="/facts/Market_segments/pRcCvKyU">market segments</a>: <i>Professional Edition</i>, <i>Carrier Grade Edition</i>, and <i>Mobilinux</i>.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> The MontaVista Linux toolkit includes specific code libraries to easily migrate from <a href="/facts/Wind_River_Systems/7unqIjwq">Wind River Systems</a>' <a href="/facts/VxWorks/DCajjp0d">VxWorks</a> and the <a href="/facts/PSOS_(real-time_operating_system)/MCX2b8KC">pSOS</a> operating systems. </p> <h4>OpenCGX</h4> <p>Project OpenCGX is an open and free to use embedded <a href="/facts/Linux/9FvCKSTq">Linux</a> distribution from MontaVista Software LLC.

DevRocket <a href="/facts/Integrated_development_environment/jbEINSQf">integrated development environment</a> (IDE) runs on Linux, <a href="/facts/Solaris_(operating_system)/KPfT98EJ">Solaris</a> and <a href="/facts/Microsoft_Windows/bwhAhuSL">Windows</a>. It uses the Eclipse <a href="/facts/C%2B%2B/Et0F2qn9">C++</a> Development Toolkit (CDT). Starting with DevRocket 5.0, users can add MontaVista's plug-ins into an existing Eclipse installation, or install Eclipse with the plugins already loaded.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p> <h2 id="services">Services</h2> <h3>Custom Hardware Enablement</h3> <h3>RTOS/Legacy Migration</h3> <h3>System Certification</h3> <p>MontaVista Linux is being used in applications within IT and telecom that need to be certified according to <a href="/facts/Common_Criteria/6Tln3R2k">Common Criteria</a>, up to <a href="/facts/EAL4%2B/RjUeSsjR">EAL4+</a> level. Evaluation Assurance Level 4+ (EAL4+) is commonly used to secure connectivity in critical environments, such as fire and police departments, or aviation and industry control systems. With the help of EAL4+ these critical environments can, for example, ensure secure and safe phone calls, control communication in-flight and for the assembly line, and achieve secure internet access. </p> <h2 id="legacy-products">Legacy products</h2> <h3>Mobilinux</h3> <p>MontaVista <a href="/facts/Mobilinux/4MFS109t">Mobilinux</a> is for wireless handsets and other mobile devices such as <a href="/facts/Global_Positioning_System/DKVLnzF3">Global Positioning System</a> (GPS) devices, portable medical devices, and wireless <a href="/facts/POS_terminal/DwUHVn2v">POS terminals</a>.

From the start, Jim Ready said he wanted to make it "100% pure Linux" under the GPL.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> The core changes to make MontaVista Linux into a real-time operating system were made by Nigel Gamble and later updated by <a href="/facts/Robert_Love/oIKDRzCx">Robert Love</a>.<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> Robert Love submitted the changes to the Linux kernel in 2001. The Linux 2.6 stable kernel series is the first to include similar features, such as priority-based <a href="/facts/Preemption_(computing)/wjgIbWel">preemption</a>. As of 2008, MontaVista had contributed 1.2% of the Linux kernel, making it the 9th-largest corporate contributor to the Linux kernel, according to a survey by the Linux Foundation.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p><p>MontaVista has also spun off independent open source projects based on several of its features, including dynamic <a href="/facts/Power_management/fWv2k2sP">power management</a>, high resolution <a href="/facts/POSIX/mQkSt234">POSIX</a> timers, the <a href="/facts/List_of_file_systems/GMUaz18t">pramfs file system</a>,<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> and the <i>openais</i> implementation of the <a href="/facts/Service_Availability_Forum/kgPXlLTM">Service Availability Forum</a>'s (SA Forum) Application Interface Specification.<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> </p> <h2 id="distribution">Distribution</h2> <p class="note">Main article: <a href="/facts/List_of_devices_that_run_MontaVista_Linux/Jyo5k2yQ">List of devices that run MontaVista Linux</a></p> <p>Other versions of MontaVista Linux are used in devices made by a number of partners, including <a href="/facts/Sony_Bravia/YH7chAL3">Sony Bravia</a> TVs, <a href="/facts/NEC/YnlUsMBA">NEC</a> routers, and others, especially in <a href="/facts/Japan/U5mz0SRT">Japan</a>.<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> A version of MontaVista Linux OS is used in <a href="/facts/Dell_Latitude/UdB8hyat">Dell Latitude</a> E4200 and E4300 notebooks<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a><a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a> to provide the <a href="/facts/Latitude_ON/AFbNB0LI">Latitude ON</a> feature.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> </p><p><a href="/facts/Cisco_NX-OS/PU2fVKXt">Cisco NX-OS</a> is based on HardHat Linux.<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a> </p> <h3>Mobile phones</h3> <p><a href="/facts/Motorola/ztqczx68">Motorola</a> became the first company to use Linux on a mobile phone when it released the <a href="/facts/Motorola_A760/9TlR6jfu">Motorola A760</a> to the <a href="/facts/China/lTjIXY5p">Chinese</a> market on February 16, 2003.
