Hi,
This patch works fine with my Loongson 3A5000M laptop (L71), which
has a 7A1000 chipset without VRAM.
Can you give more details about the hardware configuration about this
laptop?
For example, by using 'lspci | grep VGA' command. I want to make sure
if the
integrated display controller are there.
Normally, the integrated graphics should not be used if there is no
dedicated
VRAM equipped. And the platform BIOS should disable it.
Here's my result of lspci:
$ sudo lspci -k | grep VGA
00:06.1 VGA compatible controller: Loongson Technology LLC DC (Display
Controller) (rev 01)
07:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] Oland [Radeon HD 8570 / R5 430 OEM / R7 240/340 / Radeon 520
OEM] (rev 87)
Thanks a lot for feedback, please feed this back to Loongson UEFI firmware team.
Update the firmware, as this is not the right way to fix a bug.
When Loongson laptop or notebook is equipped with a Radeon GPU,
the integrated graphics will not be used. Besides don't has a
dedicated VRAM, it also don't has a external video transmitters.
Therefore, the integrate graphics are completely not usable.
Please disable it on such cases.
