From: Mark Haverkamp Date: Tue, 17 May 2005 01:28:42 +0000 (-0700) Subject: [SCSI] 2.6 aacraid: Variable FIB size (updated patch) X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7c00ffa314bf0fb0e23858bbebad33b48b6abbb9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git [SCSI] 2.6 aacraid: Variable FIB size (updated patch) New code from the Adaptec driver. Performance enhancement for newer adapters. I hope that this isn't too big for a single patch. I believe that other than the few small cleanups mentioned, that the changes are all related. - Added Variable FIB size negotiation for new adapters. - Added support to maximize scatter gather tables and thus permit requests larger than 64KB/each. - Limit Scatter Gather to 34 elements for ROMB platforms. - aac_printf is only enabled with AAC_QUIRK_34SG - Large FIB ioctl support - some minor cleanup Passes sparse check. I have tested it on x86 and ppc64 machines.
