* [POWERPC] Fix i2c-powermac platform device usageBenjamin Herrenschmidt2006-10-101-13/+15
| | | | | | | | | | | | i2c-powermac was written & merged right after Russell King's changes adding platform_driver... which I missed. Thus it still used struct device, causing crashes when hitting sleep/wakeup callbacks (it happened to work by luck so far, until early/late callbacks got added). This causes crashes on sleep/wakeup on PowerBooks with 2.6.19. The patch fixes it by using a proper platform_driver.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-0514-19/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* [PATCH] i2c: Prevent deadlock on i2c client registrationJean Delvare2006-09-301-12/+13
| | | | | | | | | | | | | | Delay the call to adapter->client_register() until after we are certain that the client registration is a success. At this point the client is fully initialized and we no longer hold the adapter->clist mutex, so this should prevent the deadlocks if the client_register() callback needs to take that mutex too, as is the case for the bttv driver.

(It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

This solves at least a problem reported by Clem Taylor: http://www.linux-mips.org/archives/linux-mips/2006-05/msg00240.html (1% of I2C transactions would timeout) Signed-off-by: Domen Puncer <domen.puncer@ultra.si> Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Perform some basic coding style cleanups while we're here (mainly space-based indentation replaced by tabulations.)

* | | i2c: __must_check fixes, i2c-devJean Delvare2006-09-261-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2c: __must_check fixes (i2c-dev) Check for error on sysfs file creation. Check for error on device creation. Delete sysfs file on device destruction. I couldn't test this one beyond compilation, as it applies on top of another patch in Greg's tree [1] which breaks all my systems when I apply it (my udev isn't recent enough.) Anyone with bleeding edge udev is welcome to test and report.

Check for error on device registration. Check for error on class device registration. Greg, I am not familiar with completion, can you please tell me if I need to take care of it in the error paths (as I did in this patch, see /* Needed? */ comments), or if it isn't needed? These patches were tested, including forced errors, so they should work fine. But of course more testing can't hurt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2c-dev: Drop the client template Drop the i2c-dev client template. This saves about 360 bytes of memory.

* | | i2c-dev: Use a list for data storageJean Delvare2006-09-261-20/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2c-dev: Use a list for data storage Use a list instead of a static array for storing the i2c-dev data. Given that most systems have less than 10 i2c busses, most of the space was wasted, so this saves around 1 kB of memory (2 kB on 64-bit archs.) The drawback is that lookup was in O(1) and is now in O(N), but given that the values of N are always small, I don't think this is a problem.
