[Question] Is it safe to use ioremap_cache for EPF' BAR mem?

[Li Chen <lchen.firstlove@xxxxxxxxxxxx>]

Hi all,

Say that I have one controller run under EP-mode and its bar 2 is mapped into a large DRAM area actually.  pci_ioremap and its friends just use ioremap internally and are non-cachable by default, so the speed is really slow(in my case write 28m/s and read 3m/d). I wonder is it safe to use ioremap_cache for this bar?


Regards,
Li
