After the end of the loop PollingCnt should be -1 but because it's an unsigned char, it's actually 255 and the timeout code never runs.

Also got some reference register setting from silicon guys for different baud rates, which tries to keep the pre-scalar register value to 16.

During this section tty_lock is held. However tty_lock is temporarily dropped in the middle of the function by tty_ldisc_hangup. The fix is to introduce a new flag which we set during the unlocked window and check it in tty_reopen too. The flag is TTY_HUPPING and is cleared after TTY_HUPPED is set. While at it, remove duplicate TTY_HUPPED set_bit. The one after calling ops->hangup seems to be more correct. But anyway, we hold tty_lock, so there should be no difference. Also document the function it does that kind of crap. Nicely reproducible with two forked children: static void do_work(const char *tty) { if (signal(SIGHUP, SIG_IGN) == SIG_ERR) exit(1); setsid(); while (1) { int fd = open(tty, O_RDWR|O_NOCTTY); if (fd < 0) continue; if (ioctl(fd, TIOCSCTTY)) continue; if (vhangup()) continue; close(fd); } exit(0); } Signed-off-by: Jiri Slaby <jslaby@suse.cz> Reported-by: <Valdis.Kletnieks@vt.edu> Reported-by: Kyle McMartin <kyle@mcmartin.ca> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This means tty_reopen is called without TTY_LDISC set. For further considerations, note tty_lock is held in tty_open. TTY_LDISC is cleared in: 1) __tty_hangup from tty_ldisc_hangup to tty_ldisc_enable. During this section tty_lock is held. However tty_lock is temporarily dropped in the middle of the function by tty_ldisc_hangup. 2) tty_release via tty_ldisc_release till the end of tty existence. If tty->count <= 1, tty_lock is taken, TTY_CLOSING bit set and then tty_ldisc_release called. tty_reopen checks TTY_CLOSING before checking TTY_LDISC. 3) tty_set_ldisc from tty_ldisc_halt to tty_ldisc_enable. We: * take tty_lock, set TTY_LDISC_CHANGING, put tty_lock * call tty_ldisc_halt (clear TTY_LDISC), tty_lock is _not_ held * do some other work * take tty_lock, call tty_ldisc_enable (set TTY_LDISC), put tty_lock I cannot see how 2) can be a problem, as there I see no race. OTOH, 1) and 3) can happen without problems. This patch the case 3) by checking TTY_LDISC_CHANGING along with TTY_CLOSING in tty_reopen. 1) will be fixed in the following patch. Nicely reproducible with two processes: while (1) { fd = open("/dev/ttyS1", O_RDWR); if (fd < 0) { warn("open"); continue; } close(fd); } -------- while (1) { fd = open("/dev/ttyS1", O_RDWR); ld1 = 0; ld2 = 2; while (1) { ioctl(fd, TIOCSETD, &ld1); ioctl(fd, TIOCSETD, &ld2); } close(fd); } Signed-off-by: Jiri Slaby <jslaby@suse.cz> Reported-by: <Valdis.Kletnieks@vt.edu> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

The USB core maps urbs for DMA if hcd->self.uses_dma is true. (hcd->self.uses_dma is true for MUSB as well). Split the uses_dma flag into two - one that says if the controller needs to use PIO for control transfers, and another which says if the controller uses DMA (for all other transfers). Also, populate this flag for all MUSB by default. (Tested on OMAP3 and OMAP4 boards, with EHCI and MUSB HCDs simultaneously in use).

The patch does fix the g_ether issue below: - use fifo_mode 3 to enable double buffer - 'ping -s 1024 IP_OF_BEAGLE_XM' - one usb packet of 512 byte is lost, so ping failed, which can be observed by wireshark note: Beagle xm takes musb rtl1.8 and may fallback to pio mode for unaligned buffer.

If, for some reason, dma channel programming fails, musb code will fallback to PIO mode to transfer that request. In that case, we need to unmap the buffer back to CPU. MUSB RTL1.8 and above cannot handle buffers which are not 32bit aligned. That happens to every request sent by g_ether gadget driver. Since the buffer sent was unaligned, we need to fallback to PIO. Because of that, g_ether was failing due to missing buffer unmapping. With this patch and [1] g_ether works fine with all MUSB revisions. Verified with OMAP3630 board, which has MUSB RTL1.8 using g_ether and g_zero.

It disables SuperSpeed terminations, which means that devices will never connect at SuperSpeed on that port. For USB 2.0/1.1 ports, disabling the port meant that the USB core could always get a connect status change later. That's not true with USB 3.0 ports. Do not let the USB core disable SuperSpeed ports. We can't rely on the device speed in the port status registers, since that isn't valid until there's a USB device connected to the port. Instead, we use the port speed array that's created from the Extended Capabilities registers.

We cannot read the port speed bits in the PORTSC registers at init time to determine the port speed, since those bits are only valid when a USB device is plugged into the port. Instead, we read the "Supported Protocol Capability" registers in the xHC Extended Capabilities space. Those describe the protocol, port offset in the PORTSC registers, and port count. We use those registers to create two arrays of pointers to the PORTSC registers, one for USB 3.0 ports, and another for USB 2.0 ports. A third array keeps track of the port protocol major revision, and is indexed with the internal xHCI port number. This commit is a bit big, but it should be queued for stable because the "Don't let the USB core disable SuperSpeed ports" patch depends on it. There is no other way to determine which ports are SuperSpeed ports without this patch.

I have seen that the reset-device and configure-endpoint commands, which are invoked from xhci_discover_or_reset_device() and xhci_configure_endpoint(), will sometimes time out. After much debugging, I determined that the commands themselves do not actually time out, but rather their completion events do not get delivered to the right place. This happens when the command ring has just wrapped around, and it's enqueue pointer is left pointing to the link TRB. xhci_discover_or_reset_device() and xhci_configure_endpoint() use the enqueue pointer directly as their command TRB pointer, without checking whether it's pointing to the link TRB. When the completion event arrives, if the command TRB is pointing to the link TRB, the check against the command ring dequeue pointer in handle_cmd_in_cmd_wait_list() fails, so the completion inside the command does not get signaled. The patch below fixes the timeout problem for me. This should be queued for the 2.6.35 and 2.6.36 stable trees.

If it does not, we use 8 registers per page. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
