This is a major change in our platform configuration. At the moment the VExpress_GEM5_V1 and VExpress_GEM5_V2 platforms both instantiate an HDLcd device. As the presence of the device can slow down host performances when the software stack is aware of its presence, we have historically been providing an entry in the hdlcd DTB node to "hide" the entry from the DTB parser: status = "disable"; This default entry in the hdlcd node will in fact prevent the driver from bringing up the device. Unfortunately this is useful for experienced users only which are aware of this knob. In order to make things more transparent, and to avoid any confusion (e.g. having the hdlcd present in the config.ini, but not being able to program it in Linux) we are deprecating this solution; we are removing the HDLcd from the aforementioned platforms. Users not interested on simulating a display controller won't notice the difference. Users interested on including it, will now have to switch to a new VExpress_GEM5_Vx_HLCD platform which will enabled the HDLcd without any further tweaking required JIRA: https://gem5.atlassian.net/browse/GEM5-866 Change-Id: I4b1920efe764080115a57f52d8a3df2e6e2386a0 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/38796 Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>
