* libata: fix probe time irq printoutsOlof Johansson2007-06-091-0/+3
| | | | | | | | | | | | | | Most drivers don't seem to fill out the host->irq field, resulting in the wrong (no) irq being reported at probe time. For example, sil24 on my system: ata1: SATA max UDMA/100 cmd 0xd00008009001f000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0 ata2: SATA max UDMA/100 cmd 0xd000080090021000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0 Since they're allocated and set up in ata_host_activate(), just save them away there.

| | | | | | | | | | | | | | | | | | | | | | This patch (as901) fixes an oversight in ohci-hcd. The hub_status_data routine must not try to access the controller's memory-mapped registers if the controller is in a low-power state; such attempts will cause a crash on some architectures (such as PPC).

| * USB: cxacru: ignore error trying to start ADSL in atm_startSimon Arlott2007-06-081-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sysfs adsl_status attribute ignores (aside from returning -EIO to the user) any error sending a START/STOP command to the device and there is at least one firmware which never sends a response but appears to work regardless. Therefore atm_start should also continue if an error is received so that such firmware is usable. The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond. Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.

| * USB: cxacru: create sysfs attributes in atm_start instead of bindSimon Arlott2007-06-081-20/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since usbatm doesn't set the usb_interface driver data until after calling bind and heavy_init, it would be NULL when the sysfs attributes are read. Reading the MAC address from atm_dev before atm_dev exists would have been be possible too. Calling create_device_file in atm_start will avoid this problem, and the data is useless until the first status poll runs. However, it must be ready before a status poll does a printk on line status change otherwise userspace could react before the files exist. For completeness I've moved remove_device_file to atm_stop so it's not called in unbind when it's not needed. There's no point starting ADSL if atm_start could still fail either.

| * USB: usb gadgets avoid le{16,32}_to_cpup()David Brownell2007-06-085-24/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that le16_to_cpup() and le32_to_cpup() aren't always safe to call with pointers into packed structures, since those are inlined functions and GCC may lose the "packed" attribute. So those references can become unaligned kernel accesses, which are evil on some hardware. This patch updates uses of those routines in the gadget stack. The references into packed structures can just use leXX_to_cpu(*x), which in most cases is more natural. Some other uses in RNDIS, mostly in debug code, were wrong in the first place; those use get_unaligned().

* | sata_promise: use TF interface for polling NODATA commandsTejun Heo2007-06-081-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sata_promise uses two different command modes - packet and TF. Packet mode is intelligent low-overhead mode while TF is the same old taskfile interface. As with other advanced interface (ahci/sil24), ATA_TFLAG_POLLING has no effect in packet mode. However, PIO commands are issued using TF interface in polling mode, so pdc_interrupt() considers interrupts spurious if ATA_TFLAG_POLLING is set. This is broken for polling NODATA commands because command is issued using packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING. Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued using TF interface if ATA_TFLAG_POLLING is set. This patch fixes detection failure introduced by polling SETXFERMODE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The statistics block DMA on 5708 can be messed up occasionally on the average of about once per hour. If the user is reading the counters within one second after the corruption, the counters will be all messed up. One second later, the counters will be ok again until the next corruption occurs. The workaround is to disable the periodic statistics DMA. Instead, we manually trigger the DMA once a second in bnx2_timer(). This manual trigger of the DMA avoids the problem. As a consequence, we can only allow 0 or 1 second settings for ethtool -C statistics block. Thanks to Jean-Daniel Pauget <jd@disjunkt.com> and CaT <cat@zip.com.au> for reporting this rare problem.

Also, I feel like this is a policy decision that shouldnt be in the kernel in the first place. People who have been lazy and boot with uclinux mtd maps and dont put root= into their commandline can simply add the appropriate root= line either into their bootloader or into the compiled in bootargs.

* | | libata: always use polling SETXFERTejun Heo2007-06-042-15/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several people have reported LITE-ON LTR-48246S detection failed because SETXFER fails. It seems the device raises IRQ too early after SETXFER. This is controller independent. The same problem has been reported for different controllers. So, now we have pata_via where the controller raises IRQ before it's ready after SETXFER and a device which does similar thing. This patch makes libata always execute SETXFER via polling. As this only happens during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is also moved from issue hot path to ata_dev_set_xfermode() - the only place where SETXFER can be issued. Note that ATA_TFLAG_POLLING applies only to drivers which implement SFF TF interface and use libata HSM. More advanced controllers ignore the flag. This doesn't matter for this fix as SFF TF controllers are the problematic ones. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Moves quiesce, thread and interrupt shutdown into aacraid drivers' .shutdown handler. This fix to the aac_shutdown handler will remove the superfluous reset of the adapter during a (clean) kexec. This fix may mitigate the active investigation 'kexec and aacraid broken' but it is unlikely to affect the root cause (issue likely present in both kexec and kdump). This patch reduces the chance the problem will occur with a kexec. The fix for root cause is currently expected to be the minimum value check to the aacraid.startup_timeout driver variable after an adapter reset within aacraid_commit_reset.patch submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.
