| 7c7dce9 | Alexander Viro | 14 January 2006, 20:29:55 UTC | [PATCH] Fix double decrement of mqueue_mnt->mnt_count in sys_mq_open Fixed the refcounting on failure exits in sys_mq_open() and cleaned the logics up. Rules are actually pretty simple - dentry_open() expects vfsmount and dentry to be pinned down and it either transfers them into created struct file or drops them. Old code had been very confused in that area - if dentry_open() had failed either in do_open() or do_create(), we ended up dentry and mqueue_mnt dropped twice, once by dentry_open() cleanup and then by sys_mq_open(). Fix consists of making the rules for do_create() and do_open() same as for dentry_open() and updating the sys_mq_open() accordingly; that actually leads to more straightforward code and less work on normal path.

Problem report (against 2.4.x driver) from Jeff Layton <jlayton@redhat.com>: An OEM noticed that the U6 qla2200 driver would hang for around 2 minutes at boot time and then proceed normally. I found that the delay was occurring when loading the new firmware into the card, and was due to a schedule_timeout(10) added to the bottom of the polling loop. Some testing showed that the load ram operation on the card was very quick (on the order of a couple of jiffies), but the sleep in the polling loop was making each operation take around 25-30. The attached patch corrects this by making it skip sleeping during the load ram operation, since I believe we only do that when the module is plugged in. It also skips sleeping if the mbox_int flag got set during the current loop. This corrected the hang on my test setup, and OEM also confirmed that it corrected the problem for them.

The proper solution is to figure out what type of pages filesystems can use so we do not have to add tests like this or handle it in the block layer for all network block drivers but the issue still has not been resolved on fs-devel so we are sending this patch as a temporary fix. This is last patch just in case it is Nakd with the explanation that we need to push the correct fix through fs-devel, mm or the block layer.

Instead of doing the lib, I just kept everything in scsi_trnapsort_iscsi.c like the FC and SPI class. This was becuase the driver model and sysfs class is tied to the session and connection setup so separating did not buy very much at this time. The reason for this patch was becuase HW iscsi LLDs like qla4xxx cannot use the iscsi class becuase the scsi_host was tied to the interface and class code. This patch just seperates the session from scsi host so that LLDs that allocate the host per some resource like pci device can still use the class. This is also fixes a couple refcount bugs that can be triggered when users have a sysfs file open, close the session, then read or write to the file.

When adding support for the integrated raid of fusion sas devices we ran into a problem with that, as it didn't allow adding virtual raid volumes without the transport class knowing about it. So this patch adds a user_scan attribute instead, that takes over from scsi_scan_host_selected if the transport class sets it and thus lets the transport class control the user-initiated scanning. As this plugs the hole about user-initiated scanning the target_parent hook goes away and we rely on callers of the scanning routines to do something sensible. For SAS this meant I had to switch from a spinlock to a mutex to synchronize the topology linked lists, in FC they were completely unsynchronized which seems wrong.

I approve this patch to dpt_i2o.c, and am applying it to the Adaptec branch of the driver. Thanks for the investigation Ryoji. --- In linux 2.6.15, data transfer does hang when both dpt_i2o and i2o_block drivers are loaded. It seems that location of pci_request_regions() are wrong. I moved it just behind pci_enable_device() like other drivers, and it becomes fine.

This code kicks in after the glue code creates a platform_device with the right platform_data. That data includes I/O loops, which will usually come from expanding an inline function (provided in the header). One goal is that the I/O loops should be easily optimized down to a few GPIO register accesses, in common cases, for speed and minimized overhead. This understands all the currently defined protocol tweaking options in the SPI framework, and might eventually serve as as reference implementation. - different word sizes (1..32 bits) - differing clock rates - SPI modes differing by CPOL (affecting chip select and I/O loops) - SPI modes differing by CPHA (affecting I/O loops) - delays (usecs) after transfers - temporarily deselecting chips in mid-transfer A lot of hardware could work with this framework, though common types of controller can't reach peak performance without switching to a driver structure that supports pipelining of transfers (e.g. DMA queues) and maybe controllers (e.g. IRQ driven).

Key differences from those two: - Uses the new SPI framework (minimalist version) - <linux/spi/ads7846.h> abstracts board-specific touchscreen info - Sysfs attributes for the temperature and voltage sensors - Uses fewer ARM-specific IRQ primitives The temperature and voltage sensors show up in sysfs like this: $ pwd /sys/devices/platform/omap-uwire/spi2.0 $ ls bus@ input:event0@ power/ temp1 vbatt driver@ modalias temp0 vaux $ cat modalias ads7846 $ cat temp0 991 $ cat temp1 1177 $ So far only basic testing has been done. There's a fair amount of hardware that uses this sensor, and which also runs Linux, which should eventually be able to use this driver. One portability note may be of special interest. It turns out that not all SPI controllers are happy issuing requests that do things like "write 8 bit command, read 12 bit response". Most of them seem happy to handle various word sizes, so the issue isn't "12 bit response" but rather "different rx and tx write sizes", despite that being a common MicroWire convention. So this version of the driver no longer reads 12 bit native-endian words; it reads 16-bit big-endian responses, then byteswaps them and shifts the results to discard the noise.

If there's got to be a mid-layer for something so simple, that's the right size budget. :) - The guts use board-specific SPI device tables to build the driver model tree. (Hardware probing is rarely an option.) - This version of Kconfig includes no drivers. At this writing there are two known master controller drivers (PXA/SSP, OMAP MicroWire) and three protocol drivers (CS8415a, ADS7846, DataFlash) with LKML mentions of other drivers in development. - No userspace API. There are several implementations to compare. Implement them like any other driver, and bind them with sysfs. The changes from last version posted to LKML (on 11-Nov-2005) are minor, and include: - One bugfix (removes a FIXME), with the visible effect of making device names be "spiB.C" where B is the bus number and C is the chipselect. - The "caller provides DMA mappings" mechanism now has kerneldoc, for DMA drivers that want to be fancy. - Hey, the framework init can be subsys_init. Even though board init logic fires earlier, at arch_init ... since the framework init is for driver support, and the board init support uses static init. - Various additional spec/doc clarifications based on discussions with other folk. It adds a brief "thank you" at the end, for folk who've helped nudge this framework into existence. As I've said before, I think that "protocol tweaking" is the main support that this driver framework will need to evolve.

We need to setup platform devices and platform data for these devices to match arch/ppc usage. Also add a helper function (get_immrbase) that reports the base address of the MMIO registers on the SOC.

Rather than having each board implement a spin loop just let the generic code do it.

| 7a45fb1 | Andy Whitcroft | 13 January 2006, 12:35:49 UTC | [PATCH] powerpc: oprofile cpu type names clash with other code In 2.6.15-git6 a change was commited in the oprofile support in the powerpc architecture. It introduced the powerpc_oprofile_type which contains the define G4. This causes a name clash with the existing wacom usb tablet driver. CC [M] drivers/usb/input/wacom.o drivers/usb/input/wacom.c:98: error: conflicting types for `G4' include/asm/cputable.h:37: error: previous declaration of `G4' CC [M] drivers/usb/mon/mon_text.o make[3]: *** [drivers/usb/input/wacom.o] Error 1 make[2]: *** [drivers/usb/input] Error 2 The elements of an enum declared in global scope are effectivly global identifiers themselves. As such we need to ensure the names are unique. This patch updates the later oprofile support to use unique names.

| 80f15dc | Paul Mackerras | 13 January 2006, 23:11:39 UTC | powerpc: Provide a suitable AT_PLATFORM value The glibc folks want to use AT_PLATFORM to select between possible alternative versions of shared libraries. This commit makes the kernel supply an AT_PLATFORM string that indicates what class of processor we are running on. Processors with the same set of user-level instructions and roughly the same instruction scheduling characteristics are given the same AT_PLATFORM value; for example, 821, 823 and 860 are all reported as "ppc823", and 7447, 7447A, 7448, 7450, 7451, 7455 are all called "ppc7450". The intention is that the AT_PLATFORM values match the values that gcc accepts for the -mcpu= option. For values which are numeric (e.g. -mcpu=750), "ppc" has been prepended. This also adds a PPC_FEATURE_BOOKE bit to the AT_HWCAP value and sets it for the 440 family and the Freescale 85xx family.
