Subject: CFT - patch to fix ehci hang on shutdown
To: current@freebsd.org


I've got an AMD 64 X2 machine that uses the recent NVIDIA GeForce 7050 /
nForce 630a chipset that hangs on shutdown.  It hangs with both UP and
SMP kernels, and with both FreeBSD 6.2-STABLE and 7.0-CURRENT.  The
problem appears to be that a delay is needed between the the call

        EOWRITE4(sc, EHCI_USBCMD, EHCI_CMD_HCRESET);

in ehci_shutdown(), and the call

        cparams = EREAD4(sc, EHCI_HCCPARAMS);

in ehci_pci_givecontroller().


There are three instances of a code sequence that does a controller
reset in ehci.c, one of which, in ehci_init(), inserts some delays and
periodically polls the controller to look for the completion of the
reset.  It seems to make sense to encapsulate the latter version of the
sequence in a separate function, and then call that function from
ehci_reset(), ehci_detach(), and ehci_shutdown().  I implemented this in
the attached patch, and it fixes shutdown problem for me on both
7.0-CURRENT and 6.2-STABLE (with some minor tweaks for the latter).

I've tested this patch on this system with both i386 and amd64 kernels,
and I also tested it on my Pentium-M laptop.  The shutdown problems are
gone and everything else looks normal, but I don't have any USB 2.0
peripherals to do further testing.  I'd appreciate any testing that can
be done in the next serveral days before I ask re@ for approval to
commit this to -CURRENT.
