| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kerneloops.org is reporting a lot of these warnings that come due to vmware not setting up any MTRRs for emulated CPUs: | Reported 709 times (14696 total reports) | BIOS bug (often in VMWare) where the MTRR's are set up incorrectly | or not at all | | This warning was last seen in version 2.6.29-rc2-git1, and first | seen in 2.6.24. | | More info: | http://www.kerneloops.org/searchweek.php?search=mtrr_trim_uncached_memory Keep a one-liner KERN_INFO about it - so that we have so notice if empty MTRRs are caused by native hardware/BIOS weirdness.

| * x86: correct the CPUID pattern for MSR_IA32_MISC_ENABLE availabilityH. Peter Anvin2009-01-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: re-enable CPUID unmasking on affected processors As far as I am capable of discerning from the documentation, MSR_IA32_MISC_ENABLE should be available for all family 0xf CPUs, as well as family 6 for model >= 0xd (newer Pentium M). The documentation on this isn't ideal, so we need to be on the lookout for errors, still. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | | | This kernel symbol provides a way for drivers to switch on alternate function for a certain GPIO pin. Turning it off is done implicitly when changing the GPIO direction, as that would be fixed when using the given pin als alternate function.

* | MIPS: RB532: Simplify dev3 initPhil Sutter2009-01-301-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | As rb532_dev3_ctl_res is not used by any platform device, it can be dropped when not used for holding the physical address of the device 3 controller. Also a size of one byte should suffice when ioremapping the physical address mentioned above, as only a single byte is being read from and written to it.

* | MIPS: RB532: Remove {get,set}_434_reg()Phil Sutter2009-01-301-27/+0
| | | | | | | | | | | | | | | | These kernel symbols are unused. Also, since dev3 init has been moved to devices.c, set_434_reg() breaks compiling as it uses dev3. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: Move dev3 init code to devices.cPhil Sutter2009-01-302-39/+39
| | | | | | | | | | | | | | | | | | This code doesn't belong to gpio.c, as it's completely unrelated to GPIO. As dev1 and dev2 init code is in devices.c, it seems to be a more adequate place. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: Fix set_latch_u5()Phil Sutter2009-01-301-1/+1
| | | | | | | | | | | | | | | | | | The data to be written is just a byte, so use writeb instead of writel. Also, dev3.base contains the address, not the data so referencing here is wrong. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: Fix init of rb532_dev3_ctl_resPhil Sutter2009-01-301-2/+3
| | | | | | | | | | | | | | | | This register just contains the address of the actual resource, so initialisation has to be the same as cf_slot0_res and nand_slot0_res. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: Use driver_data instead of platform_dataPhil Sutter2009-01-301-1/+1
| | | | | | | | | | | | | | | | | | As the korina ethernet driver uses platform_get_drvdata() to extract the driver specific data from the platform device, driver_data has to be used here. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: Detect uart type, add platform devicePhil Sutter2009-01-302-1/+27
| | | | | | | | | | | | | | | | | | Auto-detection works just fine, so use it instead of specifying the type manually. Also define a platform device for the uart, as suggested by David Daney. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: remove useless CF GPIO initialisationPhil Sutter2009-01-301-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | As the pata-rb532-cf driver calls gpio_direction_input(), the calls to rb532_gpio_set_func() and rb532_gpio_direction_input() are not needed since the alternate function is automatically being disabled when changing the GPIO pin direction. The later two calls to rb532_gpio_set_{ilevel,istat}() are implicitly being done by the IRQ initialisation of pata-rb532-cf.

* | MIPS: RB532: Auto disable GPIO alternate functionPhil Sutter2009-01-301-4/+4
| | | | | | | | | | | | | | | | | | | | When a driver calls gpio_set_direction_{input,output}(), it obviously doesn't want the alternate function for that pin to be active (as the direction would not matter in that case). This patch ensures alternate function is disabled when the direction is being changed. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* | MIPS: RB532: Add set_type() function to IRQ struct.Phil Sutter2009-01-302-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupt Group 4 mapps the GPIO pins enabled as interrupt sources; add defines to make this clear when addressing them later in code. The mapped GPIOs support triggering on either level high or low. To achieve this, the set_type() function calls rb532_gpio_set_ilevel() for interrupts of the above mentioned group. As there is no way to alter the triggering characteristics of the other interrupts, accept level triggering on status high only. (This is just a guess; but as the system boots fine and interrupt-driven devices (e.g. serial console) work with no implications, it seems to be right.) To clear a GPIO mapped IRQ, the source has to be cleared (i.e., the interrupt status bit of the corresponding GPIO pin). This is done inside rb532_disable_irq(). After applying these changes I could undo most of my former "fixes" to pata-rb532-cf. Particularly all interrupt handling can be done generically via set_irq_type() as it was before.

| | | | | | | | | | | | | | | | | | | | The algorithm works unconditionally. If bitval is one, the first line is a no op and the second line sets the bit at offset position. Vice versa, if bitval is zero, the first line clears the bit at offset position and the second line is a no op.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit "alpha: teach the compiler that BUG doesn't return" (ed6b9b97f42c091630335bfb71a2931e6f86388b) moved the asm code into inline function which takes __FILE__ and __LINE__ as arguments. This violates asm constrains there ("i" - an immediate operand with constant value), so that compile may result in warning or error, depending on compiler version. Just adding an infinite loop to the BUG() is sufficient.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _PAGE_COHERENT is now always set in _PAGE_RAM resp. PAGE_KERNEL. Thus it has to be masked out, if the BAT mapping should be non cacheable or CPU_FTR_NEED_COHERENT is not set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the VIO bus code the wrappers for dma alloc_coherent and free_coherent calls are rounding to IOMMU_PAGE_SIZE. Taking a look at the underlying calls, the actual mapping is promoted to PAGE_SIZE. Changing the rounding in these two functions fixes under-reporting the entitlement used by the system. Without this change, the system could run out of entitlement before it believes it has and incur mapping failures at the firmware level. Also in the VIO bus code, the wrapper for dma map_sg is not exiting in an error path where it should. Rather than fall through to code for the success case, this patch adds the return that is needed in the error path.
