Hello Thomas,

I'm preparing patches to add proper memory-region requests across legacy fbdev drivers (use of request_mem_region/pci_request_region/devm_request_mem_region where appropriate) to avoid conflicts between fbdev and DRM drivers. I’ve started making changes (examples: pvr2fb.c, macfb.c, cyber2000fb.c, xilinxfb.c).

Before I prepare a patch series, could you please advise:

Preferred format: a single combined patch or a series of smaller patches? If a series, do you prefer one patch per driver file, per driver family, or grouped another way?
Any drivers or areas to exclude or treat specially (e.g., vga16fb or VGA-exclusive ranges)?
Any tests or checks you expect before posting (build, boot smoke tests, Kconfig options to verify)?
I can prepare an initial series and send it for review; I’ll follow your preferred format. Thanks for guidance.

Please send one patch per driver. The rest is up to you.

Best regards
Thomas


Thank you,
Chintan Patel
