Steve, Were you trying to patch the Beta kernel with patches from "patch level 14 release"? You may have missed the LSP 1.20 GA release. The patches from "Patch level 14 release" cleanly apply to the LSP 1.20 GA kernel. The default series file picks patches 1, 9 - 14. The patches 2 - 8 are for the custom MMC/SD stack.
LSP 1.20, with patch level 14, we have reported the following - USB MSC Host Read: 6.4 MBytes/sec USB MSC Host Write: 6.3 MBytes/sec The procedure followed to measure the performance is documented in the datasheet - http://focus.ti.com/lit/an/sprs496a/sprs496a.pdf BTW, we also have a LSP 2.00 Beta release, which is based on MV Pro 5.0.0 (2.6.18) on the software update advisor site. USB MSC Host performance has improved with this release: USB MSC Host Read: 13.4 MBytes/sec USB MSC Host Write: 7.3 MBytes/sec Thanks Sneha ________________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stephen Berry Sent: Tuesday, November 11, 2008 4:14 PM To: [email protected]; Subbrathnam, Swaminathan Subject: USB patches (patch level 14) for LSP 1_20 I'm running into a performance issue with using USB memory sticks - namely very low write performance. I've recently ported to LSP 1_20 (from the beta) and after searching the mailing list there seemed to be some mention of a patch level 45 on the 6446 that would fix this issue... But of course for the Dm355 distribution on the Ti update site, patch level 14 is the current one. And to top it off, they don't apply cleanly with quilt. So before I go through each patch individually I'd like to make sure that these patches will help with my problem. Most of the comments seem to be relating to OTG functionality - but the patch labeled lsp_1_20_usb_intr_schedule_fix_014.patch - sounds like it could be helpful. Any help is appreciated, Steve _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
