Subject: Re: [06/12] arch: Declare screen_info in <asm/screen_info.h>
Date: Fri, 18 Aug 2023 22:04:38 +0800 [thread overview]
Message-ID: <924934b8-d2ca-c1ea-b357-202c2f995adc@loongson.cn> (raw)
In-Reply-To: <20230629121952.10559-7-tzimmermann@suse.de>
Hi,
Why this patch get dropped in the end?
Since the global screen_info is an arch-specific thing,
Whenever an arch-neutral module or subsystem references the global screen_info,
There are some complaints from either compile testing robot.
Well, a programmer may handle it by using the CONFIG_SYSFB guard,
but it is not as precise as what this patch provided.
Personally, I think this patch is still valuable.
I suggest either forcing all other architectures to export screen_info,
like the X86 and IA64 arch does, after all the screen_info is a good thing.
or provide the fine-control version like this patch does.
