* DM9000: Remove cal_CRC() and use ether_crc_le insteadBen Dooks2008-02-11
| | | | | | | | | Remove the cal_CRC as this is basically wrappering the ether_crc_le function, and is only being used by the multicast hash table functions. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Fix delays used by EEPROM read and writeBen Dooks2008-02-11
| | | | | | | | | The code was using a delay of 8ms, when it should have been using the EEPROM status flag from the device to indicate the EEPROM transaction had finished. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Use netif_msg to enable debugging optionsBen Dooks2008-02-11
| | | | | | | | | | Use the netif_msg_*() macros to enable the debugging based on the board's msg_enable field. The output still goes via the dev_dbg() macros, so will be tagged and output as appropriate. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Remove unnecessary changelog in header commentBen Dooks2008-02-11

* DM9000: Ensure spinlock held whilst accessing EEPROM registersBen Dooks2008-02-11
| | | | | | | | | | Ensure we hold the spinlock whilst the registers and being modified even though we hold the overall lock. This should protect against an interrupt happening whilst we are using the device. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Remove EEPROM initialisation code.Ben Dooks2008-02-11

* DM9000: Add mutex to protect accessBen Dooks2008-02-11
| | | | | | | | | | Add a mutex to serialise access to the chip functions from entries such as the ethtool and the MII code. This should reduce the amount of time the spinlock is held to protect the address register. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Remove barely used SROM array read.Ben Dooks2008-02-11
| | | | | | | | | | | | | | | The srom array in the board data is only being used in the device probe routines. The probe also only uses the first 6 bytes of an array we spend 512ms reading 128 bytes from. Change to reading the MAC area directly to the MAC address structure. As a side product, we rename the read_srom_word to dm9000_read_eeprom to bring it into line with the rest of the driver. No change is made to the delay in this function, which will be dealt with in a later patch. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Use msleep() instead of udelay()Ben Dooks2008-02-11
| | | | | | | | | | | | We can use sleeping functions when reading and writing the PHY registers, so let us sleep instead of busy waiting for the PHY. Note, this also fixes a bug reading the PHY where only 100uS was being used instead of 150uS Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Do not sleep with spinlock and IRQs heldBen Dooks2008-02-11
| | | | | | | | | | | | | | The phy read and write routines call udelay() with the board lock held, and with the posibility of IRQs being disabled. Since these delays can be up to 500usec, and are only required as we have to save the chip's address register. To improve the behaviour, hold the lock whilst we are writing and then restore the state before the delay and then repeat the process once the delay has happened.

* DM9000: Remove old timer based poll routinesBen Dooks2008-02-11
| | | | | | | | | | | | | | | | | | | Remove the timer based MII phy polling, as this is currently broken with the new EEPROM code that now uses mutexes to protect the phy access. This will need to be replaced in the future by some form of mutex safe mechanism for reading the MII phy status. The replacement has not been done here as changing this patch, which is early in the sequence has quite a knock-on effect. Once this series is merged, then a new presentation of an patch to poll the MII link status can be added. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* DM9000: Pass IRQ flags via platform resourcesBen Dooks2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | Use the flags in the IRQ resource to specify the type of IRQ being requested, so that systems which do not have level-based interrupts, or change the interrupt in some other way can specify this without making an #ifdef mess in the driver. This is specifically designed to undo the change in commit 4e4fc05a2b6e7bd2e0facd96e0c18dceb34d9349 which hardwires the type for everyone but blackfin to IRQT_RISING, which breaks all a number of Simtec boards which use (and setup in the bootloader) active low IRQs. Note, although there where originally objections due to the use of IORESOURCE_IRQ and IRQT_ flags not sharing the same definition, at least <include/linux/interrupt.h> notes these are the same.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] Fix dm9000 release_resourceDirk Opfer2006-09-11
| | | | | | | | | | | | | | | | | | | | dm9000_release_board calls release_resource with the platform resource instead of the requested resource: db->addr_res = platform_get_resource(pdev, IORESOURCE_MEM, 0); db->addr_req = request_mem_region(db->addr_res->start, i, pdev->name); dm9000_release_board: if (db->addr_res != NULL) { release_resource(db->addr_res); kfree(db->addr_req); With this behavior the kernel will crash on the second removal.
