* [PATCH] blk: fix tag shrinking (revive real_max_size)Tejun Heo2005-08-051-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My patch in commit fa72b903f75e4f0f0b2c2feed093005167da4023 incorrectly removed blk_queue_tag->real_max_depth. The original resize implementation was incorrect in the following points. * actual allocation size of tag_index was shorter than real_max_size, but assumed to be of the same size, possibly causing memory access beyond the allocated area. * bits in tag_map between max_deptn and real_max_depth were initialized to 1's, making the tags permanently reserved. In an attempt to fix above two bugs, I had removed allocation optimization in init_tag_map and real_max_size. Tag map/index were allocated and freed immediately during resize. Unfortunately, I wasn't considering that tag map/index can be resized dynamically with tags beyond new_depth active. This led to accessing freed area after shrinking tags and led to the following bug reporting thread on linux-scsi. http://marc.theaimsgroup.com/?l=linux-scsi&m=112319898111885&w=2 To fix the problem, I've revived real_max_depth without allocation optimization in init_tag_map, and Andrew Vasquez confirmed that the problem was fixed. As Jens is not going to be available for a week, he asked me to make sure that this patch reaches you. http://marc.theaimsgroup.com/?l=linux-scsi&m=112325778530886&w=2 Also, a comment was added to make sure that real_max_size is needed for dynamic shrinking.

* [PATCH] tpm_infineon: Support for new TPM 1.2 and PNPACPIMarcel Selhorst2005-08-052-44/+113
| | | | | | | | | | | | | | | This patch includes support for the new Infineon Trusted Platform Module SLB 9635 TT 1.2 and does further include ACPI-support for both chip versions (SLD 9630 TT 1.1 and SLB9635 TT 1.2). Since the ioports and configuration registers are not correctly set on some machines, the configuration is now done via PNPACPI, which reads out the correct values out of the DSDT-table. Note that you have to have CONFIG_PNP, CONFIG_ACPI_BUS and CONFIG_PNPACPI enabled to run this driver (assuming that mainboards including a TPM do have the need for ACPI anyway).

* | [PATCH] rtc: msleep() cannot be used from interruptPetr Vandrovec2005-08-051-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the beginning of July my Opteron box was randomly crashing and being rebooted by hardware watchdog. Today it finally did it in front of me, and this patch will hopefully fix it. The problem is that at the end of June (the 28th, to be exact: commit 47f176fdaf8924bc83fddcf9658f2fd3ef60d573, "[PATCH] Using msleep() instead of HZ") rtc_get_rtc_time was converted to use msleep() instead of busy waiting. But rtc_get_rtc_time is used by hpet_rtc_interrupt, and scheduling is not allowed during interrupt. So I'm reverting this part of original change, replacing msleep() back with busy loop. The original code was busy waiting for up to 20ms, but on my hardware in the worst case update-in-progress bit was asserted for at most 363 passes through loop (on 2GHz dual Opteron), much less than even one jiffie, not even talking about 20ms. So I changed code to just wait only as long as necessary. Otherwise when RTC was set to generate 8192Hz timer, it stopped doing anything for 20ms (160 pulses were skipped!) from time to time, and this is rather suboptimal as far as I can tell.

* | [PATCH] USB: ehci: microframe handling fixDavid Brownell2005-08-054-9/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch has a one line oops fix, plus related cleanups. - The bugfix uses microframe scheduling data given to the hardware to test "is this a periodic QH", rather than testing for nonzero period. (Prevents an oops by providing the correct answer.) - The cleanup going along with the patch should make it clearer what's going on whenever those bitfields are accessed. The bug came about when, around January, two new kinds of EHCI interrupt scheduling operation were added, involving both the high speed (24 KBytes per millisec) and low/full speed (1-64 bytes per millisec) microframe scheduling. A driver for the Edirol UA-1000 Audio Capture Unit ran into the oops; it used one of the newly supported high speed modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In yenta_socket, we default to using the resource setting of the CardBus bridge. However, this is a PCI-bus-centric view of resources and thus needs to be converted to generic resources first. Therefore, add a call to pcibios_bus_to_resource() call in between. This function is a mere wrapper on x86 and friends, however on some others it already exists, is added in this patch (alpha, arm, ppc, ppc64) or still needs to be provided (parisc -- where is its pcibios_resource_to_bus() ?).

* | [PATCH] PCI: restore BAR values after D3hot->D0 for devices that need itJohn W. Linville2005-08-052-5/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration (including BARs) when transitioning from D3hot->D0. This leaves such a device in an inaccessible state. The patch below causes the BARs to be restored when enabling such a device, so that its driver will be able to access it. The patch also adds pci_restore_bars as a new global symbol, and adds a correpsonding EXPORT_SYMBOL_GPL for that. Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a (re)boot. Most drivers call pci_enable_device very early, so devices left in D3hot that lose configuration during the D3hot->D0 transition will be inaccessible to their drivers. Drivers could be modified to account for this, but it would be difficult to know which drivers need modification. This is especially true since often many devices are covered by the same driver. It likely would be necessary to replicate code across dozens of drivers. The patch below should trigger only when transitioning from D3hot->D0 (or at boot), and only for devices that have the "no soft reset" bit cleared in the PM control register. I believe it is safe to include this patch as part of the PCI infrastructure. The cleanest implementation of pci_restore_bars was to call pci_update_resource. Unfortunately, that does not currently exist for the sparc64 architecture. The patch below includes a null implemenation of pci_update_resource for sparc64. Some have expressed interest in making general use of the the pci_restore_bars function, so that has been exported to GPL licensed modules. Signed-off-by: John W.

| * | [SCSI] fix aic7xxx performance issues since 2.6.12-rc2James Bottomley2005-08-041-9/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several people noticed we dropped quite a bit on benchmark figures. OK, it was my fault but unfortunately I discovered I ran out of brown paper bags a while ago and forgot to reorder them. The issue is that a construct introduced in the conversion of the driver to use the transport class keyed off whether the block request was tagged or not. However, the aic7xxx driver doesn't properly set up the block layer TCQ (it uses the wrong API), so the driver now things all requests are untagged and we keep it to a queue depth of a single element. Oops. The fix is to use the correct TCQ API. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removing the SCSI tape module results in an oops in class_device_destroy if any devices are present. The patch at the end of this message fixes the bug by moving class_destroy() later in exit_st() so that the class still exists when devices are removed. (The bug is old but class_simple_device_remove() did nothing when the class did not exist.) The patch also fixes a "class leak" in init_st() error path.

Firstly, R1BIO_Degraded was being set in a number of places in the resync code, but is never used there, so get rid of those settings. Then: When doing a resync, we want to clear the bit in the bitmap iff the array will be non-degraded when the sync has completed. However the current code would clear the bitmap if the array was non-degraded when the resync *started*, which obviously isn't right (it is for 'resync' but not for 'recovery' - i.e. rebuilding a failed drive). This patch calculated 'still_degraded' and uses the to tell bitmap_start_sync whether this sync should clear the corresponding bit.

Turning off OIER[E3] as suggested in the existing comment does not work. I posted a note to the ARM mailing list a little while ago asking for opinions from people using SA1100. There was one reponse from Nico who believes that the SA1100 is the same as the PXA255 in this respect. You also asked me to involve the watchdog maintainer which I tried to do but didn't hear anything back. There are only a couple of other drivers which can't stop the watchdog and there seems to be no consistancy regarding printing an error etc. I decided to print something since that matches the case for all the other drivers when NOWAYOUT is turned on. Also, I changed the device .name to "watchdog" like most of the other watchdogs. udev uses it as the device name (by default) and spaces etc. get in the way. Superceded 2833/1 because 2.6.13-rc4 caused rejects. Signed-off-by: Ian Campbell <icampbell@arcom.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have increased PCIBIOS_MIN_IO to 0x4000, but still want motherboard resources to be allocated properly. So we need to state 0x1000 (according to the comment) limit explicitely. Signed-off-by: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | | | | pci: make bus resource start address override minimum IO addressLinus Torvalds2005-08-021-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason we have PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO is because we want to protect badly documented motherboard PCI resources and thus don't want to allocate new resources in low IO/MEM space. However, if we have already discovered a PCI bridge with a specified resource base, that should override that decision. This change will allow us to move the "careful" region upwards without resulting in problems allocating resources in low mappings. This was brought on by us having allocated a bus resource at 0x1000, conflicting with a undocumented VAIO Sony PI resources.
* | | | | [PATCH] cfq-iosched: fix problem with barriers and max_depth == 1Jens Axboe2005-08-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CFQ will currently stall when using write barriers and the default max_depth setting of 1, since we artificially need a depth of 2 when pre-pending the first flush. So never deny the barrier request going to the device. This is a regression since 2.6.12, it was found in SUSE testing.

This all worked in 2.6.12. Looking at the code in yenta_socket.c, function yenta_allocate_res, it's obvious what is wrong: if we get to line 639 (i.e. there wasn't a usable preassigned resource), we will always flow through to line 668, which is the printk that I was seeing, even if a resource was successfully allocated. It looks to me as though there should be a return statement after the two config_writel's in each of the 3 branches of the if statements, so that the function returns after successfully setting up the resource. The patch below adds these return statements, and with this patch, cardbus works on my powerbook once again.
