* ARM: DMA: Replace page_to_dma()/dma_to_page() with pfn_to_dma()/dma_to_pfn()Russell King2011-01-03
| | | | | | | | | | | | Replace the page_to_dma() and dma_to_page() macros with their PFN equivalents. This allows us to map parts of memory which do not have a struct page allocated to them to bus addresses. This will be used internally by dma_alloc_coherent()/dma_alloc_writecombine(). Build tested on Versatile, OMAP1, IOP13xx and KS8695. Tested-by: Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: simplify early machine init hooksRussell King2010-12-24
| | | | | | | | | | Rather than storing each machine init hook separately, store a pointer to the machine description record and dereference this instead. This pointer is only available while the init sections are present, which is not a problem as we only use it from init code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: 6538/1: Subarch IRQ handler macros V3Magnus Damm2010-12-24
| | | | | | | | | | | | | | | | Per subarch interrupt handler macros V3. This patch breaks out code from the irq_handler macro into arch_irq_handler and arch_irq_handler_default. The macros are put in the header file "entry-macro-multi.S" The arch_irq_handler_default macro is designed to be used by irq_handler in entry-armv.S while arch_irq_handler is suitable for per-subarch use.

* ARM: 6532/1: Allow machine to specify it's own IRQ handlers at run-timeeric miao2010-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Normally different ARM platform has different way to decode the IRQ hardware status and demultiplex to the corresponding IRQ handler. This is highly optimized by macro irq_handler in entry-armv.S, and each machine defines their own macro to decode the IRQ number. However, this prevents multiple machine classes to be built into a single kernel. By allowing each machine to specify thier own handler, and making function pointer 'handle_arch_irq' to point to it at run time, this can be solved. And introduce CONFIG_MULTI_IRQ_HANDLER to allow both solutions to work. Comparing with the highly optimized macro of irq_handler, the new function must be written with care not to lose too much performance. And the IPI stuff on SMP is expected to move to the provided arch IRQ handler as well. The assembly code to invoke handle_arch_irq is optimized by Russell King.

* ARM: Ensure experimental options are so markedRussell King2010-12-05

* ARM: implement support for read-mostly sectionsRussell King2010-12-05
| | | | | | | | | | | As our SMP implementation uses MESI protocols. Grouping together data which is mostly only read together means that we avoid unnecessary cache line bouncing when this code shares a cache line with other data. In other words, cache lines associated with read-mostly data are expected to spend most of their time in shared state. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* ARM: 6467/1: amba: optional PrimeCell core voltage switchLinus Walleij2010-11-26
| | | | | | | | | | | | | | | | | | | | | On some contemporary sub-micron SoCs, peripherals on the chip have power domain switches, i.e. the voltage to the core may be turned off to conserve power. In the Ux500 we have this for out PrimeCell derivates. This patch makes it possible to specify an (optional) regulator to handle the voltage domain switch on AMBA PrimeCells, modeled very similar to how block clocks are handled. Additional amba_vcore_[enable|disable] calls are supplied to make it possible introduce optional powering off of the core voltage. Using this will require code to spool/unspool any core HW state.

* ARM: 6396/1: Add SWP/SWPB emulation for ARMv7 processorsLeif Lindholm2010-11-04
| | | | | | | | | | | | | | | | | | | | The SWP instruction was deprecated in the ARMv6 architecture, superseded by the LDREX/STREX family of instructions for load-linked/store-conditional operations. The ARMv7 multiprocessing extensions mandate that SWP/SWPB instructions are treated as undefined from reset, with the ability to enable them through the System Control Register SW bit. This patch adds the alternative solution to emulate the SWP and SWPB instructions using LDREX/STREX sequences, and log statistics to /proc/cpu/swp_emulation. To correctly deal with copy-on-write, it also modifies cpu_v7_set_pte_ext to change the mappings to priviliged RO when user RO.

* ARM: 6384/1: Remove the domain switching on ARMv6k/v7 CPUsCatalin Marinas2010-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the domain switching functionality via the set_fs and __switch_to functions on cores that have a TLS register. Currently, the ioremap and vmalloc areas share the same level 1 page tables and therefore have the same domain (DOMAIN_KERNEL). When the kernel domain is modified from Client to Manager (via the __set_fs or in the __switch_to function), the XN (eXecute Never) bit is overridden and newer CPUs can speculatively prefetch the ioremap'ed memory. Linux performs the kernel domain switching to allow user-specific functions (copy_to/from_user, get/put_user etc.) to access kernel memory. In order for these functions to work with the kernel domain set to Client, the patch modifies the LDRT/STRT and related instructions to the LDR/STR ones. The user pages access rights are also modified for kernel read-only access rather than read/write so that the copy-on-write mechanism still works. CPU_USE_DOMAINS gets disabled only if the hardware has a TLS register (CPU_32v6K is defined) since writing the TLS value to the high vectors page isn't possible. The user addresses passed to the kernel are checked by the access_ok() function so that they do not point to the kernel space.

The driver deals with much shorter times (<200ms). This will fix a rare division by zero bug in Mode1. This could happen, when the work is not executed in time (within mode1_latency) after the interrupt. In this case the DAC33 will not receive the needed nSample command in time, and enters to an unknown state, and won't recover. In such event the time window will increase, and eventually going to be bigger than 1s, resulting devision by zero.

There is just one LED on the device. The LED can either be On or it can be set to Blink. There doesn't seem to be a way to switch it off. The control message to change LED status is similar to that of audigy2nx except that the index is to be set to 0 and value is 1 for Blink and 0 for On. The 'Power LED' control in alsamixer when muted will cause the LED to Blink continuously. When unmuted the LED will stay On. The Creative driver under Windows sets the LED to blink whenever audio is muted. This LED can be treated as the CMSS LED but I figured since there is just one LED, it should be treated as the Power LED. Is that alright? I've also changed the comment "Usb X-Fi" to "Usb X-Fi S51" as there are other external X-Fi devices from Creative like Usb X-Fi Go and Xmod.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When expanding a parameterised string we may run out of space, this triggers a realloc. When computing the new allocation size we do not allow for the terminating '\0'. Allow for this when calculating the new length.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Very recently, the RS485 interface has been fixed by adding two further fields (see commit 1b6331848b69d1ed165a6bdc75c4046d68767563). Check the value of the flag SER_RS485_RTS_BEFORE_SEND before delaying. Signed-off-by: Claudio Scordino <claudio@evidence.eu.com> Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
