<b>Subject:</b> Re: [PATCH] drm/i915: Discard large BIOS framebuffers causing display corruption.</font>

<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">I haven't observed "display corruption", but on my MacBookPro16,1 the bottom<br>
and right edges of the TTY are not on the screen, so a few lines of text<br>
cannot be seen.<br>
<br>
This also occurs on the internal displays of all (as far as I know) other<br>
2018-2020 Intel Macbooks when using the Intel GPU (The 15" and 16" ones<br>
also have an AMDGPU, but this issue occurs when they have the Intel GPU<br>
set as the boot gpu).<br>
<br>
There's a similar patch that hasn't been sent upstream that people with these<br>
Macbooks have been using:<br>
