XGBE:

1. [XGBE]: Force mode(Auto negotiation disabled) is not supported in RJ45.
2. Sporadically 2.5G Network is established after a delay of more than 20 sec for SFP 2.5 on Port 0/1.
3. 10G SFP Hot plug(FC) is not working with NetGear switch(XS724EM model)
4. Can’t concurrently enable SFP+ and RJ45 interfaces.
5. No IEEE 1588 Timestamp support.
6. No receive Split header support.
7. Following features should be functional but have not been fully validated: Priority and VLAN (VLAN Priority Control), RMON Counter, VLAN support and Receive-Side scaling, 2.5G TCP/IP offload (duplex) and 2.5G jumbo frames (duplex).

Below is the type of SFP/RJ45 modules used in the XGBE validation of this release.

FreeSync:

1. Only one monitor should be attached to system.
2. The game should be running in fullscreen mode.
3. In case of mGPU, Xorg should be configured for multiscreen mode with only one monitor attached to the GPU where freesync is to be enabled. Please note that window managers should also have good support for multiscreen mode.
4. Supported only on DP.

MultiGPU:

1. Maximum framebuffer / viewport size supported by the GFX engine is 16K. When more than 8 2K monitors are arranged horizontally, we hit this limitation and corruption is observed on a few monitors. To overcome this limitation, the monitors must be re-arranged in a way that 16K limit is not exceeded. Xrandr can be used for this.
2. Beyond 8 monitors, the display doesn’t come up. Xrandr via ssh needs to be used to achieve the goal of not exceeding 16k limit.

Third Party Issues/Limitations:

1. Terminal switching results in hard hang randomly. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
2. Switching to console mode upon hotplug results in soft hang. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
3. Mpv overnight test fails with loopback option.
   Workaround: Use script for continuous playback.
4. Stutter can be observed when stream framerate and monitor refresh rate are different. This is expected phenomenon. Stutter cab be minimized with interpolation option in mpv. But it can introduce corruption and other side effects.

XGBE:

1. [XGBE]: Force mode(Auto negotiation disabled) is not supported in RJ45.
2. Sporadically 2.5G Network is established after a delay of more than 20 sec for SFP 2.5 on Port 0/1.
3. 10G SFP Hot plug(FC) is not working with NetGear switch(XS724EM model)
4. Can’t concurrently enable SFP+ and RJ45 interfaces.
5. No IEEE 1588 Timestamp support.
6. No receive Split header support.
7. Following features should be functional but have not been fully validated: Priority and VLAN (VLAN Priority Control), RMON Counter, VLAN support and Receive-Side scaling, 2.5G TCP/IP offload (duplex) and 2.5G jumbo frames (duplex).

Below is the type of SFP/RJ45 modules used in the XGBE validation of this release.

FreeSync:

1. Only one monitor should be attached to system.
2. The game should be running in fullscreen mode.
3. In case of mGPU, Xorg should be configured for multiscreen mode with only one monitor attached to the GPU where freesync is to be enabled. Please note that window managers should also have good support for multiscreen mode.
4. Supported only on DP.

MultiGPU:

1. Maximum framebuffer / viewport size supported by the GFX engine is 16K. When more than 8 2K monitors are arranged horizontally, we hit this limitation and corruption is observed on a few monitors. To overcome this limitation, the monitors must be re-arranged in a way that 16K limit is not exceeded. Xrandr can be used for this.
2. Beyond 8 monitors, the display doesn’t come up. Xrandr via ssh needs to be used to achieve the goal of not exceeding 16k limit.

Third Party Issues/Limitations:

1. Terminal switching results in hard hang randomly. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
2. Switching to console mode upon hotplug results in soft hang. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
3. Mpv overnight test fails with loopback option.
   Workaround: Use script for continuous playback.
4. Stutter can be observed when stream framerate and monitor refresh rate are different. This is expected phenomenon. Stutter cab be minimized with interpolation option in mpv. But it can introduce corruption and other side effects.

3. 10G SFP Hot plug(FC) is not working with NetGear switch(XS724EM model)
4. Can’t concurrently enable SFP+ and RJ45 interfaces.
5. No IEEE 1588 Timestamp support.
6. No receive Split header support.
7. Following features should be functional but have not been fully validated: Priority and VLAN (VLAN Priority Control), RMON Counter, VLAN support and Receive-Side scaling, 2.5G TCP/IP offload (duplex) and 2.5G jumbo frames (duplex).

Below is the type of SFP/RJ45 modules used in the XGBE validation of this release.

FreeSync:

1. Only one monitor should be attached to system.
2. The game should be running in fullscreen mode.
3. In case of mGPU, Xorg should be configured for multiscreen mode with only one monitor attached to the GPU where freesync is to be enabled. Please note that window managers should also have good support for multiscreen mode.
4. Supported only on DP.

MultiGPU:

1. Maximum framebuffer / viewport size supported by the GFX engine is 16K. When more than 8 2K monitors are arranged horizontally, we hit this limitation and corruption is observed on a few monitors. To overcome this limitation, the monitors must be re-arranged in a way that 16K limit is not exceeded. Xrandr can be used for this.
2. Beyond 8 monitors, the display doesn’t come up. Xrandr via ssh needs to be used to achieve the goal of not exceeding 16k limit.

Third Party Issues/Limitations:

1. Terminal switching results in hard hang randomly. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
2. Switching to console mode upon hotplug results in soft hang. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
3. Mpv overnight test fails with loopback option.
   Workaround: Use script for continuous playback.
4. Stutter can be observed when stream framerate and monitor refresh rate are different. This is expected phenomenon. Stutter cab be minimized with interpolation option in mpv. But it can introduce corruption and other side effects.

XGBE:

1. SFP wont work on V1807 platforms after few hours.
2. Ethernet Link is showing always up on RJ45 ports of Bilby platforms.
   Workaround: Disable the port which is not connected the ethernet cable.
3. Hot plug failures and stability issue with longer duration performance test on Bilby platforms with RG45 ports enabled.
   Workaround: Disable the port which is not connected the ethernet cable.
4. Peer to Peer network is unstable with 1/10G SFP (FC).
5. Can’t concurrently enable SFP+ and RJ45 interfaces.
6. No IEEE 1588 Timestamp support.
7. No receive Split header support.
8. Following features should be functional but have not been fully validated: Priority and VLAN (VLAN Priority Control), RMON Counter, VLAN support and Receive-Side scaling, 2.5G TCP/IP offload (duplex) and 2.5G jumbo frames (duplex).

   Below is the type of SFP/RJ45 modules used in the XGBE validation of this release.

   Type	Model
   1G SFP - RJ45	BEL
   1G SFP - RJ45	Finisar
   10G SFP+ passive direct cable	Finisar
   10G SFP optical	Finisar
   10G SFP optical	Intel
   10G SFP optical	Intel

FreeSync:

1. Only one monitor should be attached to system.
2. The game should be running in fullscreen mode.
3. In case of mGPU, Xorg should be configured for multiscreen mode with only one monitor attached to the GPU where freesync is to be enabled. Please note that window managers should also have good support for multiscreen mode.
4. Supported only on DP.

MultiGPU:

1. Maximum framebuffer / viewport size supported by the GFX engine is 16K. When more than 8 2K monitors are arranged horizontally, we hit this limitation and corruption is observed on a few monitors. To overcome this limitation, the monitors must be re-arranged in a way that 16K limit is not exceeded. Xrandr can be used for this.
2. Beyond 8 monitors, the display doesn’t come up. Xrandr via ssh needs to be used to achieve the goal of not exceeding 16k limit.

Third Party Issues/Limitations:

1. Terminal switching results in hard hang randomly. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
2. Switching to console mode upon hotplug results in soft hang. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
3. Mpv overnight test fails with loopback option.
   Workaround: Use script for continuous playback.
4. Stutter can be observed when stream framerate and monitor refresh rate are different. This is expected phenomenon. Stutter cab be minimized with interpolation option in mpv. But it can introduce corruption and other side effects.

XGBE:

1. SFP wont work on V1807 platforms after few hours.
2. Ethernet Link is showing always up on RJ45 ports of Bilby platforms.
   Workaround: Disable the port which is not connected the ethernet cable.
3. Hot plug failures and stability issue with longer duration performance test on Bilby platforms with RG45 ports enabled.
   Workaround: Disable the port which is not connected the ethernet cable.
4. Peer to Peer network is unstable with 1/10G SFP (FC).
5. Can’t concurrently enable SFP+ and RJ45 interfaces.
6. No IEEE 1588 Timestamp support.
7. No receive Split header support.
8. Following features should be functional but have not been fully validated: Priority and VLAN (VLAN Priority Control), RMON Counter, VLAN support and Receive-Side scaling, 2.5G TCP/IP offload (duplex) and 2.5G jumbo frames (duplex).

   Below is the type of SFP/RJ45 modules used in the XGBE validation of this release.

   Type	Model
   1G SFP - RJ45	BEL
   1G SFP - RJ45	Finisar
   10G SFP+ passive direct cable	Finisar
   10G SFP optical	Finisar
   10G SFP optical	Intel
   10G SFP optical	Intel

FreeSync:

1. Only one monitor should be attached to system.
2. The game should be running in fullscreen mode.
3. In case of mGPU, Xorg should be configured for multiscreen mode with only one monitor attached to the GPU where freesync is to be enabled. Please note that window managers should also have good support for multiscreen mode.
4. Supported only on DP.

MultiGPU:

1. Maximum framebuffer / viewport size supported by the GFX engine is 16K. When more than 8 2K monitors are arranged horizontally, we hit this limitation and corruption is observed on a few monitors. To overcome this limitation, the monitors must be re-arranged in a way that 16K limit is not exceeded. Xrandr can be used for this.
2. Beyond 8 monitors, the display doesn’t come up. Xrandr via ssh needs to be used to achieve the goal of not exceeding 16k limit.

Third Party Issues/Limitations:

1. Terminal switching results in hard hang randomly. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
2. Switching to console mode upon hotplug results in soft hang. Issue root caused gnome which is third party component.
   https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1758512
3. Mpv overnight test fails with loopback option.
   Workaround: Use script for continuous playback.
4. Stutter can be observed when stream framerate and monitor refresh rate are different. This is expected phenomenon. Stutter cab be minimized with interpolation option in mpv. But it can introduce corruption and other side effects.
