This should bring the same functionality when the bootp/dhcp work is done by loader(8) as r297150 does for the in-kernel BOOTP case. 2016-02-29T09:03:07Z Stanislav Galabov sgalabov@FreeBSD.org 2016-02-29T09:03:07Z urn:sha1:55d11ce3bd8b04287e8a569e94a579568c29efe9 Approved by: adrian (mentor) 2016-02-29T07:27:49Z Stanislav Galabov sgalabov@FreeBSD.org 2016-02-29T07:27:49Z urn:sha1:b981b8bd869140a572e5cfa713d4c6f67d1534ab ubldr. The changes are mostly dealing with removing unnecessary casts from the U-Boot API (we're passing only pointers, no obvious reason to cast them to uint32_t), cleaning up some compiler warnings and using the proper printf format specifiers in order to be able to compile cleanly for both 32-bit and 64-bit MIPS targets.

The code which splits a serverip:/rootpath string into rootip and a plain pathname is now a separate net_parse_rootpath() function that can be called by others. The code that sets the kernel env vars needed for nfs_diskless is moved into net_open() so that the variables get set no matter where the params came from. There was already code in net_open() that allowed for the possibility that some other entity has set up the network-related global variables. It uses the rootip variable as the key, assuming that if it is set all the other required variables are set too. These changes don't alter the existing behavior, they just make it easier to actually write some new code to get the params from another source (such as the U-Boot environment). 2010-01-09T21:23:39Z Marius Strobl marius@FreeBSD.org 2010-01-09T21:23:39Z urn:sha1:ccb1921ee03062ec2bcde59bc7a77cfacc36ad3d by keeping it opened after the first open and closing it via the cleanup handler when NETIF_OPEN_CLOSE_ONCE is defined in order to avoid the open-close-dance on every file access which with firmware that for example performs an auto-negotiation on every open causes netbooting to take horribly long. Basically the behavior with this knob enabled resembles the one employed between r60506 and r177108 (and for sparc64 also again since r182919) with the addition that the network device now is closed eventually before entering the kernel and before rebooting. Actually I think this should be the desired MI behavior, however the U-Boot loader actually requires net_close() to be called after every transaction in order for some local shutdown operations to be performed (and which I think thus will break on concurrent opens, i.e. when netdev_opens is > 1, like the loader does at least for disks when LOADER_GZIP_SUPPORT is enabled). - Use NETIF_OPEN_CLOSE_ONCE to replace the hack, which artificially increased netdev_opens for sparc64 in order to keep the network device opened forever, as at least some firmware versions require the network device to be closed eventually before entering the kernel or otherwise will DMA received packets to stale memory. The powerpc OFW loader probably wants NETIF_OPEN_CLOSE_ONCE to be set as well for the same reasons. 2010-01-09T17:09:57Z Marius Strobl marius@FreeBSD.org 2010-01-09T17:09:57Z urn:sha1:989bac19ead202eca7b234054dcb3e75b5a531fa license FreeBSD had in sys/boot).

Certain firmwares (U-Boot) need local shutdown operations to be performed on a network controller upon transaction end: such platform-specific hooks are supposed to be called via netif_close() (from within net_close()). This change effectively reverts the following CVS commit: sys/boot/common/dev_net.c revision 1.7 date: 2000/05/13 15:40:46; author: dfr; state: Exp; lines: +2 -1 Only probe network settings on the first open of the network device. The alpha firmware takes a seriously long time to open the network device the first time. Also suppress excessive output while netbooting via loader, unless debugging. While there, make sys/boot/uboot more style(9) compliant. Reviewed by: imp Approved by: cognet (mentor)
