But this bit only controls the routing of card functional interrupts, not the CSC interrupts which are used for interrupt probing. A bad side effect of messing with this register in yenta_probe_irq() is that it can lead to irq storms if a card is inserted and already powered by the BIOS. Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them. The problem is, once they are created, the driver will not be able to access the devices correctly without this patch.

In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

Associated with this, aac_insert_entry can be removed, SavedIrql can be removed & padding variable can be removed. With the movement of SavedIrql out & replaced with an automatic variable qflags, the locking can be refined somewhat. The sparse warnings did not catch the need for byte swapping in the 'dprintk' debugging print macros, so fixed this up when this code was moved outside of the now refined locking.

MAC_RX_MODE reset must be done before setting up the MAC_MODE register on 5705_PLUS chips or the chip will stop receiving after a while. The MAC_RX_MODE reset is needed to prevent intermittently losing the first receive packet on serdes chips. 2. Skip MAC loopback test on 5780 because of hardware errata. Normal traffic including PHY loopback is not affected by the errata. 3. PHY loopback fails intermittently on 5708S and this is fixed by putting the PHY in loopback mode first before programming the MAC mode register. A MAC_RX_MODE reset is also added. 4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow nway_reset if 5780S is in parallel detect mode. 5. Add missing PHY IDs in KNOWN_PHY_ID() macro.

While the queue_if_no_path variable is correctly set to 1, the saved_queue_if_no_path gets set to 0. When the device is subsequently made live (resumed), the saved value (0) always overwrites the live value (1) so the option *always* gets turned off. The fix adds a parameter to the queue_if_no_path() function to indicate whether the previous value should be preserved or not - if not, as when the device is being set up, the saved value is set to the new value (1).

This error message is bogus for two reasons. First, it can never occur given that current code takes care to initialize IOC4 in such a way that these "unknown" interrupts could never occur. Second, this code fails to take into account that other drivers can share the IOC4 interrupt mechanism through SA_SHIRQ, and thus this driver is not in-fact "all-knowing". Finally, this error message triggers every time some "unknown" interrupt occurs -- it's not rate limited or repetition limited in any way, thereby effectively denying use of the console device. Given its bogosity in the first place, it's best to just get rid of it entirely.

I don't know if the new 14" iBooks also have that chip, so they might also be supported. The chip identifies itself as "RV350 NV" (pci id 0x4e56), revision 0x80. Apple calls it "Snowy", xfree86 names it "ATI FireGL Mobility T2 (M11) NV (AGP)". So, we seem to be lucky here: The suspend-code for the M10 (which also is a "RV350 NV") works flawless for that chip.

Test for VIA K8T800 north bridge instead of AMD K8 HyperTransport bridge based on new information from Andi Kleen. The AMD HyperTransport interface is not responsible for PCI transactions and so the re-ordering is more likely done by the VIA north bridge. This code is subject to change if we get more information from AMD or VIA. PCI Express devices are excluded from doing the read flush since all chipsets in the write_reorder list are PCI chipsets.

There is one exception in net/ipv4/route.c which is in fact a pre-existing race condition. I've marked it as such so that we remember to fix it.

It turns out that the problem is one of padding (the firmware cksum engine works only on 32-bit chunks, yuck), so the special casing for length == 1 wasn't sufficient anyway. This patch addresses the issue, as well the other issue of i386 + CONFIG_HIGHMEM being broken. It is pretty much the same workaround that Adaptec themselves used in their Windows driver. I have yet to check if it fixes the problem when the skb is non-linear, but this patch _will_ solve the problem for 99% of the users out there (those not using sendfile).

This leads me to believe that this framebuffer would have problems in X, but since there hasn't been a weitek driver for X in several millennia, this isn't something that I can confirm or deny.

It may "forget" to service one in some circumstances, including when one of the drive is suspended (it will eventually fail to service the slave when the master is suspended for example). This prevents the wakeup requests that gets queued on wakeup from sleep from beeing serviced in some cases when 2 drives are sharing an IDE bus. The problem is deep enough in the way this code works (and there are probably a few other problematic but rare corner cases) and fixing it would require some major rethinking of the way IDE decides which channel to service. This is not 2.6.14 material. However, in the meantime, Bart has accepted this simple workaround that will fix the crash on wakeup from sleep since this specific corner case is actually hitting users to get into 2.6.14.

This is because the urb saves a pointer to "current" when it is posted to the device, but there's no guarantee that this pointer is still valid afterwards. In fact, there are three separate issues: 1) the pointer to "current" can become invalid, since the task could be completely gone when the URB completion comes back from the device. 2) Even if the saved task pointer is still pointing to a valid task_struct, task_struct->sighand could have gone meanwhile. 3) Even if the process is perfectly fine, permissions may have changed, and we can no longer send it a signal. So what we do instead, is to save the PID and uid's of the process, and introduce a new kill_proc_info_as_uid() function.

This adds in efficiency as every packet update makes the /sys/class/firmware/dell_rbu/loading and data files to disappear and reappear again. Thus the user app needs to wait for the files to reappear to dump another packet. This slows down the packet update tremendously in case of large number of packets. I am submitting a new patch for dell_rbu which will change the way we do packet updates; In the new method the user app will create a new single file which has already packetized the rbu image and all the packets are now staged in this file. This driver also creates a new entry in /sys/devices/platform/dell_rbu/packet_size ; the user needs to echo the packet size here before downloading the packet file. The user should do the following: create one single file which has all the packets stacked together. echo the packet size in to /sys/devices/platform/dell_rbu/packet_size. echo 1 > /sys/class/firmware/dell_rbu/loading cat the packetfile > /sys/class/firmware/dell_rbu/data echo 0 > /sys/class/firmware/dell_rbu/loading The driver takes the file which came through /sys/class/firmware/dell_rbu/data and takes chunks of paket_size data from it and place in contiguous memory. This makes packet update process very efficient and fast. As all the packet update happens in one single operation. The user can still read back the downloaded file from /sys/devices/platform/dell_rbu/data.

I didn't know about messy programs like svgatextmode... Couldn't this be integrated in some linux/drivers/video/console/svgacon.c ?... So because of the existence of the svgatextmode program, the kernel is not supposed to touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ? Disabling the check in vgacon_resize() might help indeed, but I'm really not sure whether it will work for any chipset: in my patch, CRT registers are set at each console switch, since stty rows/cols apply to consoles separately... The attached solution is to keep the test, but if it fails, we assume that the caller knows what it does (i.e. it is svgatextmode) and then disable any further call to vgacon_doresize. Svgatextmode is usually used to _expand_ the display, not to shrink it. And it is harmless in the case of a too big stty rows/cols: the display will just be cropped. I tested it on my laptop, and it works fine with svgatextmode.

What happened? Highspeed HID devices are correctly recognized and enumerated by the kernel. But even if usbhid kernel module is loaded, no HID reports are received by the kernel. The output of the hardware USB analyzer told me that the host doesn't even poll for interrupt IN transfers (even the "interrupt in" USB transfer are polled by the host). After some debugging in hid-core.c I've found the reason. In case of a highspeed device, the endpoint interval is re-calculated in driver/usb/input/hid-core.c: line 1669: /* handle potential highspeed HID correctly */ interval = endpoint->bInterval; if (dev->speed == USB_SPEED_HIGH) interval = 1 << (interval - 1); Basically this calculation is correct (refer to USB 2.0 spec, 9.6.6). This new calculated value of "interval" is used as input for usb_fill_int_urb: line 1685: usb_fill_int_urb(hid->urbin, dev, pipe, hid->inbuf, 0, hid_irq_in, hid, interval); Unfortunately the same calculation as above is done a second time in usb_fill_int_urb in the file include/linux/usb.h: line 933: if (dev->speed == USB_SPEED_HIGH) urb->interval = 1 << (interval - 1); else urb->interval = interval; This means, that if the endpoint descriptor (of a high speed device) specifies e.g. bInterval = 7, the urb->interval gets the value: hid-core.c: interval = 1 << (7-1) = 0x40 = 64 urb->interval = 1 << (interval -1) = 1 << (63) = integer overflow Because of this the value of urb->interval is sometimes negative and is rejected in core/urb.c: line 353: /* too small? */ if (urb->interval <= 0) return -EINVAL; The conclusion is, that the recalculaton of the interval (which is necessary for highspeed) should not be made twice, because this is simply wrong. ;-) Re-calculation in usb_fill_int_urb makes more sense, because it is the most general approach. So it would make sense to remove it from hid-core.c. Because in hid-core.c the interval variable is only used for calling usb_fill_int_urb, it is no problem to remove the highspeed re-calculation in this file.

In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're not accessing host_info_list or host_count, and holding this lock while trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in raw1394.c:receive_iso. Test program attached reliably deadlocks all SMP machines I have been able to test without this patch.

This would only happen when resync/recovery is happening. This patch fixes three vaguely related bugs. 1/ The recent change to use kthreads got the setting of the process name wrong. This fixes it. 2/ The recent change to use kthreads lost the ability for md threads to be signalled with SIG_KILL. This restores that. 3/ There is a long standing bug in that if: - An array needs recovery (onto a hot-spare) and - The recovery is being blocked because some other array being recovered shares a physical device and - The recovery thread is killed with SIG_KILL Then the recovery will appear to have completed with no IO being done, which can cause data corruption. This patch makes sure that incomplete recovery will be treated as incomplete. Note that any kernel affected by bug 2 will not suffer the problem of bug 3, as the signal can never be delivered. Thus the current 2.6.14-rc kernels are not susceptible to data corruption. Note also that if arrays are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't occur.
