    <title>topic PCI device not map correctly for using as passthrough on Z490 chipset in ESXi Discussions</title>

    <description>&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;I have a problem with the configuration of the TBS TV tuner after switching to a new server configuration.&lt;/P&gt;&lt;P&gt;So far I've been using the configuration for several years:&lt;/P&gt;&lt;P&gt;Esxi 6.7.0&lt;BR /&gt;Processor: i7-4770S CPU&lt;BR /&gt;motherboard: Asrcok Z87 Extreme3&lt;BR /&gt;tuner: TBS 6982&lt;/P&gt;&lt;P&gt;Everything works fine, the card is easily configured after passthru and added to the linux machine.&lt;BR /&gt;Everything has been working fine and stable for years.&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;However, it's time to change the server to a newer configuration:&lt;/P&gt;&lt;P&gt;Esxi 8.0.1&lt;BR /&gt;processor: i7-10700&lt;BR /&gt;Motherboard: MSI Z490 A PRO&lt;BR /&gt;tuner: tuner: TBS 6982&lt;/P&gt;&lt;P&gt;Unfortunately, after configuring the system, it turned out that there is a problem with configuring the tuner via passthru.&lt;BR /&gt;Unfortunately, it does not appear in the device list. Other cards, e.g. LSI controller, can be configured as passthru.&lt;BR /&gt;The problem is only with this card.&lt;BR /&gt;I checked the Esx versions 6.0 6.5 6.7 7.0 8.0 and all the same - so I assume it's rather a problem with the chipset and the motherboard.&lt;/P&gt;&lt;P&gt;I also managed to make a test on another board with a processor:&lt;/P&gt;&lt;P&gt;processor: i7-8700&lt;BR /&gt;Motherboard: Asrock Z370 PRO4&lt;BR /&gt;tuner: tuner: TBS 6982&lt;/P&gt;&lt;P&gt;and unfortunately the problem also occurs!!.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Below are screenshots of what it looks like on the "old" server and the "new" one&lt;/P&gt;&lt;P&gt;In the list of devices after inserting the card, the device 1c:0 and 1c:6 appear as in the picture:&lt;/P&gt;&lt;P&gt;This is "new" server z490 chipset:&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="z490-with_TBS.jpg" style="width: 999px;"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/101762i0AAC4AD8EAC10BAC/image-size/large/is-moderation-mode/true?v=v2&amp;amp;px=999" role="button" title="z490-with_TBS.jpg" alt="z490-with_TBS.jpg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This is old "server" with Z87 chipset:&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="z87-with_TBS.jpg" style="width: 999px;"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/101763i16D4FE093BC52593/image-size/large/is-moderation-mode/true?v=v2&amp;amp;px=999" role="button" title="z87-with_TBS.jpg" alt="z87-with_TBS.jpg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;From the console it looks like this:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This is "new" server z490 chipset:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;LI-CODE lang="markup"&gt;[root@localhost:~] lspci

      <title>PCI device not map correctly for using as passthrough on Z490 chipset</title>
      <link>https://communities.vmware.com/t5/ESXi-Discussions/PCI-device-not-map-correctly-for-using-as-passthrough-on-Z490/m-p/2970601#M288396</link>
      <description>&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;I have a problem with the configuration of the TBS TV tuner after switching to a new server configuration.&lt;/P&gt;&lt;P&gt;So far I've been using the configuration for several years:&lt;/P&gt;&lt;P&gt;Esxi 6.7.0&lt;BR /&gt;Processor: i7-4770S CPU&lt;BR /&gt;motherboard: Asrcok Z87 Extreme3&lt;BR /&gt;tuner: TBS 6982&lt;/P&gt;&lt;P&gt;Everything works fine, the card is easily configured after passthru and added to the linux machine.&lt;BR /&gt;Everything has been working fine and stable for years.&lt;/P&gt;&lt;P&gt;&lt;BR /&gt;However, it's time to change the server to a newer configuration:&lt;/P&gt;&lt;P&gt;Esxi 8.0.1&lt;BR /&gt;processor: i7-10700&lt;BR /&gt;Motherboard: MSI Z490 A PRO&lt;BR /&gt;tuner: tuner: TBS 6982&lt;/P&gt;&lt;P&gt;Unfortunately, after configuring the system, it turned out that there is a problem with configuring the tuner via passthru.&lt;BR /&gt;Unfortunately, it does not appear in the device list. Other cards, e.g. LSI controller, can be configured as passthru.&lt;BR /&gt;The problem is only with this card.&lt;BR /&gt;I checked the Esx versions 6.0 6.5 6.7 7.0 8.0 and all the same - so I assume it's rather a problem with the chipset and the motherboard.&lt;/P&gt;&lt;P&gt;I also managed to make a test on another board with a processor:&lt;/P&gt;&lt;P&gt;processor: i7-8700&lt;BR /&gt;Motherboard: Asrock Z370 PRO4&lt;BR /&gt;tuner: tuner: TBS 6982&lt;/P&gt;&lt;P&gt;and unfortunately the problem also occurs!!.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Below are screenshots of what it looks like on the "old" server and the "new" one&lt;/P&gt;&lt;P&gt;In the list of devices after inserting the card, the device 1c:0 and 1c:6 appear as in the picture:&lt;/P&gt;&lt;P&gt;This is "new" server z490 chipset:&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="z490-with_TBS.jpg" style="width: 999px;"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/101762i0AAC4AD8EAC10BAC/image-size/large/is-moderation-mode/true?v=v2&amp;amp;px=999" role="button" title="z490-with_TBS.jpg" alt="z490-with_TBS.jpg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This is old "server" with Z87 chipset:&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="z87-with_TBS.jpg" style="width: 999px;"&gt;&lt;img src="https://communities.vmware.com/t5/image/serverpage/image-id/101763i16D4FE093BC52593/image-size/large/is-moderation-mode/true?v=v2&amp;amp;px=999" role="button" title="z87-with_TBS.jpg" alt="z87-with_TBS.jpg" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;From the console it looks like this:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This is "new" server z490 chipset:&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;LI-CODE lang="markup"&gt;[root@localhost:~] lspci
