From feccc30d90155bcbc937f87643182a43d25873eb Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 3 Mar 2008 15:15:59 -0500 Subject: USB: remove CONFIG_USB_PERSIST setting This patch (as1047) removes the USB_PERSIST Kconfig option, enabling it permanently. It also prevents the power/persist attribute from being created for hub devices; there's no point in having it since USB-PERSIST is always turned on for hubs.

It defines a new "L1 Suspend" state which resembles the current (L2) suspend state, except that it can be entered and exited much more quickly. It should thus be more useful for runtime PM, even though it doesn't mandate reduced power draw from VBUS. This patch provides the relevant #defines for usbcore. Actually implementing these mechanisms requires host silicon that can generate new USB packets, plus hubs handling some new requests and peripherals which understand the new packets.

My controller support a way to send raw ATA command to the disk with something call atacb (see http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf). Atacb support can be added for each application, but there is some disadvantages : - all application need to be patched - A race is possible if there other accesses, because the emulation can be split in 2 atacb scsi transactions. One for sending the command, one for reading the register (if ck_cond is set). I have implemented the emulation in usb-storage with a special proto_handler, and an unsual entry.

The URB_NO_INTERRUPT flag is now exported (this is the only behavioral change). USBDEVFS_URB_* macros are added for URB_NO_FSBR, URB_ZERO_PACKET, and URB_NO_INTERRUPT, making explicit the fact that the kernel accepts them. The flag matching takes into account that the URB_* values may change as the kernel evolves, whereas the USBDEVFS_URB_* values must remain fixed since they are a user API.
