* [ACPI] Bind PCI devices with ACPI devicesDavid Shaohua Li2005-07-123-3/+365
| | | | | | | | | | | | | | | | | | | | | | Implement the framework for binding physical devices with ACPI devices. A physical bus like PCI bus should create a 'acpi_bus_type', with: .find_device: For device which has parent such as normal PCI devices. .find_bridge: It's for special devices, such as PCI root bridge or IDE controller. Such devices generally haven't a parent or ->bus. We use the special method to get an ACPI handle.

| * When cfq I/O scheduler is selected, get_request() in __make_request() callsKiyoshi Ueda2005-06-171-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct cfq_queue) of the current process for the device and returns it. If it's not found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that get_request() fails) if no __GFP_WAIT flag. On the other hand, in __make_request(), get_request() is called without __GFP_WAIT flag at the first time. Thus, the get_request() fails when there is no existing queue, typically when it's called for the first I/O request of the process to the device. Though it will be followed by get_request_wait() for general case, __make_request() will just end the I/O with an error (EWOULDBLOCK) when the request was for read-ahead.

* | [PATCH] sbp2 slab corruption fixAlexandre Oliva2005-06-161-1/+2
|/ | | | | | | | | | | | | | | | | | This fixed a problem that showed up in the Fedora development tree a few weeks before the Fedora Core 4 release, initially as slab corruption, later as hard crashes on boot up, when slab debugging was disabled for the release. More details on the history at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=158424 The problem is caused by sbp2's use of scsi_host->hostdata[0] to hold a scsi_id, without explicitly requesting space for it. Since hostdata is declared as a zero-sized array, we don't get any such space by default, so it must be explicitly requested. The patch below implements just that.

* [PATCH] Fix PCI BAR size interpretation on 64-bit archesOlof Johansson2005-06-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | On 64-bit machines, PCI_BASE_ADDRESS_MEM_MASK and other mask constants passed to pci_size() are 64-bit (for example ~0x0fUL). However, pci_size does comparisons between the u32 arguments and the mask, which will fail even though any result from pci_size is still just 32-bit. Changing the mask argument to u32 seems the obvious thing to do, since all arithmetic in the function is 32-bit and having a larger mask makes no sense. This triggered on a PPC64 system here where an adapter (VGA, as it happened) had a memory region base of 0xfe000000 and a sz of the same, matching the if (max == maxbase ...) test at the bottom of pci_size but failing the mask comparison. Quite a corner case which I guess explains why we haven't seen it until now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Despite all the care lately in making the powermac sleep/wakeup as robust as possible, there is still a nasty related to the use of cpufreq on PMU based machines. Unfortunately, it affects paulus old powerbook so I have to fix it :) We didn't manage to understand what is precisely going on, it leads to memory corruption and might have to do with RAM not beeing properly refreshed when a cpufreq transition is done right before the sleep. The best workaround (and less intrusive at this point) we could come up with is included in this patch. We basically do _not_ force a switch to high speed on suspend anymore (that is what is causing the problem) on those machines. We still force a speed switch on wakeup (since we don't know what speed we are coming back from sleep at, and that seems to work fine). Since, during this short interval, the actual CPU speed might be incorrect, we also hack around by multiplying loops_per_jiffy by 2 (max speed factor on those machines) during early wakeup stage to make sure udelay's during that time aren't too short. For after 2.6.12, we'll change udelay implementation to use the CPU timebase (which is always constant) instead like we do on ppc64 and thus get rid of all those problems.

* | [PATCH] iseries_veth: Supress spurious WARN_ON() at module unloadMichael Ellerman2005-06-101-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My patch from a few weeks back (now in mainline), called "Cleanup skbs to prevent unregister_netdevice() hanging", can cause our TX timeout code to fire on machines with lots of VLANs (because it takes > 2 seconds between when we stop the queues and when we're finished stopping the connections). When that happens the TX timeout code freaks out and does a WARN_ON() because as far as it's concerned there shouldn't be a TX timeout happening, which is fair enough. I have a "proper" fix for this, which is to a) do refcounting on connections and b) implement a proper ack timer so we don't keep unacked skbs lying around for ever. But for 2.6.12 I propose just supressing the WARN_ON(). Users will still see the "NETDEV WATCHDOG" warning, but that's not nearly as bad as a WARN_ON() which users interpret as an Oops.

This patch was originally developed by Daniel Smertnig. I (Ian Abbott) made a few changes. It has been tested by both Daniel and I, at least for raw, non-canonical receive data processing. Here is Daniel's original description of the patch: === During a project in which I was using a FTDI 232BM to transmit data at relative high speeds (625kBit/s), I noticed a problem where data was lost even if flow control was enabled: The FTDI-Driver receives 512 Bytes of data over USB at a time, which consists of 8 64-Byte packets. Subtracting the 2 bytes of status information included in each packet this gives 496 "real" data bytes per read. This data is passed (indirectly, via the flip buffers) to the tty line discipline which takes care of throttling when there the free buffer space reaches TTY_THRESHOLD_THROTTLE (128). Because the FTDI driver processes up to 496 bytes at a time, throttling won't happen in time and the line discipline will discard the remaining bytes. To avoid this the patch passes data in 62-byte blocks to the tty layer and checks the available space in the ldisc-buffers. If there isn't enough free space, processing the rest of the data is delayed using a workqueue. Note: The original problem should be easily reproducible with a userspace program which does slow & small reads. === Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Daniel Smertnig <daniel.smertnig@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

As mentioned earlier, the current check_bridge_mode() code assumes that AGP bridges are PCI devices. This isn't always true. Definitely not for HP zx1 chipset and the same seems to be the case for SGI's AGP bridge. The patch below fixes the problem by picking up the AGP_MODE_3_0 bit from bridge->mode. I feel like I may be missing something, since I can't see any reason why check_bridge_mode() wasn't doing that in the first place. According to the AGP 3.0 specs, the AGP_MODE_3_0 bit is determined during the hardware reset and cannot be changed, so it seems to me it should be safe to pick it up from bridge->mode. With the patch applied, I can definitely use AGP acceleration both with AGP 2.0 and AGP 3.0 (one with an Nvidia card, the other with an ATI FireGL card). Unless someone spots a problem, please apply this patch so 3d acceleration can work on zx1 boxes again. This makes AGP work again on machines with an AGP bridge that isn't a PCI device.

| * | | [PATCH] AGP fix for Xen VMMKeir Fraser2005-06-0713-35/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Linux is running on the Xen virtual machine monitor, physical addresses are virtualised and cannot be directly referenced by the AGP GART. This patch fixes the GART driver for Xen by adding a layer of abstraction between physical addresses and 'GART addresses'. Architecture-specific functions are also defined for allocating and freeing the GATT. Xen requires this to ensure that table really is contiguous from the point of view of the GART. These extra interface functions are defined as 'no-ops' for all existing architectures that use the GART driver.
