| * [AVR32] extint: Set initial irq type to low levelHaavard Skinnemoen2008-01-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | David Brownell pointed out a mismatch in the avr32 extint code: > I noticed a small glitch that's not fixed by this patch: the > initial type is falling edge, but IRQ_TYPE_NONE is mapped to > IRQ_TYPE_LEVEL_LOW. Potentially surprising. Fix it by setting the initial type (and handler) to low level, matching the meaning of IRQ_TYPE_NONE. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] extint: change set_irq_type() handlingDavid Brownell2008-01-251-11/+7
| | | | | | | | | | | | | | | | Update the AVR32 EIC code to use the new __set_irq_handler_unlocked() call, getting rid of one more instance of this widespread problem. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] NMI debuggingHaavard Skinnemoen2008-01-257-10/+155
| | | | | | | | | | | | | | | | Change the NMI handler to use the die notifier chain to signal anyone who cares. Add a simple "nmi debugger" which hooks into this chain and that may dump registers, task state, etc. when it happens. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| | | | | | | | | | | | | | | | Remove the CPU selection menu and instead let it be selected by the board or daughterboard option. Add daughterboard selection for ATSTK1000 (this was previously determined based on CPU type.) Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] Add support for ATSTK1003 and ATSTK1004Haavard Skinnemoen2008-01-258-20/+1975
| | | | | | | | | | | | | | ATSTK1003 and ATSTK1004 are CPU daughterboards for ATSTK1000 featuring the AT32AP7001 and AT32AP7002 CPUs, respectively. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] Clean up external DAC setup codeHaavard Skinnemoen2008-01-252-16/+17
| | | | | | | | | | | | | | | | Reduce the ridiculous amount of #ifdef clutter in atstk1002.c a bit by moving all the extdac stuff into its own function and providing an empty stub for the case when it isn't wanted. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| * [AVR32] Add support for AT32AP7001 and AT32AP7002Haavard Skinnemoen2008-01-258-21/+51
| | | | | | | | | | | | | | | | | | These are derivatives of the AT32AP7000 chip, which means that most of the code stays the same. Rename a few files, functions, definitions and config symbols to reflect that they apply to all AP700x chips, and exclude some platform devices from chips where they aren't present. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] Provide more CPU information in /proc/cpuinfo and dmesgHaavard Skinnemoen2008-01-251-26/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the following fields to /proc/cpuinfo: * chip type and revision (from the JTAG chip id) * cpu MHz (from clk_get_rate()) * features (from the CONFIG0 register) Also rename "cpu family" to "cpu arch" and "cpu type" to "cpu core" to remove some ambiguity. Show chip type and revision at bootup, and clarify that the other kinds of IDs that we're already printing are for the cpu core and architecture. Rename "AP7000" to "AP7" since that's the name of the core. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] Oprofile supportHaavard Skinnemoen2008-01-254-0/+247
| | | | | | | | | | | | | | | | | | This adds the necessary architecture code to run oprofile on AVR32 using the performance counters documented by the AVR32 Architecture Manual. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> Acked-by: Philippe Elie <phil.el@wanadoo.fr>
| * [AVR32] Include instrumentation menuHaavard Skinnemoen2008-01-252-10/+2

| * [AVR32] Enable debugging only when neededHaavard Skinnemoen2008-01-255-9/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Keep track of processes being debugged (including the kernel itself) and turn the OCD system on and off as appropriate. Since enabling debugging turns off some optimizations in the CPU core, this fixes the issue that enabling KProbes support or simply running a program under gdbserver will reduce system performance significantly until the next reboot. The CPU performance will still be reduced for all processes while a process is being debugged, but this is a lot better than reducing the performance forever.

| * [AVR32] Remove redundant try_to_freeze() call from do_signal()Haavard Skinnemoen2008-01-251-7/+0
| | | | | | | | | | | | | | get_signal_to_deliver() will call try_to_freeze(), so there's no point in do_signal() doing it as well. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * [AVR32] Drop GFP_COMP for DMA memory allocationsHaavard Skinnemoen2008-01-251-0/+7
| | | | | | | | | | | | | | | | | | | | dma_alloc_coherent wants to split pages after allocation in order to reduce the memory footprint. This does not work well with GFP_COMP pages, so drop this flag before allocation. This patch was forward-ported from BSP 2.0 Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

* | | Kobject: the cris iop_fw_load.c code is brokenGreg Kroah-Hartman2008-01-241-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code is really really really broken. So much so that it's almost impossible to fix with a simple patch, so just comment out the offending registration with the kobject core, and mark the driver as broken. The problem is that the code is trying to register a "raw" struct device, which is not allowed. struct device is only for use within the driver model. This is being done to try to use the firmware layer which wants a struct device. To properly fix this, use something easy, like a platform device, which is a struct device and can be used for this kind of thing.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reorganizes the way suspend and resume notifications are sent to drivers. The major changes are that now the PM core acquires every device semaphore before calling the methods, and calls to device_add() during suspends will fail, while calls to device_del() during suspends will block. It also provides a way to safely remove a suspended device with the help of the PM core, by using the device_pm_schedule_removal() callback introduced specifically for this purpose, and updates two drivers (msr and cpuid) that need to use it.

Here the bootlog: Because the data field was never filled and a binary sysctl handler was never written this sysctl has never been usable through the sys_sysctl interface. So just remove the binary sysctl number. Making the kernel sanity checks happy. Signed-off-by: Eric W.
