Can cause oops under certain circumstances. Russell indicated the original optimization was required on older kernels to avoid thread starvation on memory fragmentation, but may no longer be required. I've updated the patch to 19rc4 and ensured no dain-bramage slipped in this time (sorry about that). Original description follows: I was given some test results which pointed to an Oops in alloc_thread_info (happened 2x), and after looking at the code, I see that ARM has its own local cache of 4 struct thread_info. There wasn't any clear (to me) synchronization between the alloc_thread_info and the free_thread_info. I looked over the other arch, and they all simply allocate them on an as needed basis, so I simplified the ARM to do the same, based on the other arch (e.g. PPC) and the folks doing the testing have indicated that this fixed the oops.

This patch introduces the global 'at91_extern_irq' variable that contains a bitset of the available external interrupt sources. The processor reset mechanism also differs on the various AT91 processors. This patch also adds a global 'at91_arch_reset' callback (from system.h) into the processor-specific code to perform the reset.

Victor Date: Thu, 30 Nov 2006 14:34:53 +0100 Subject: [ARM] 3950/1: AT91: Split up system header file The AT91RM9200 system header file (at91rm9200_sys.h) has been split into separate header files for each peripheral. This was necessary since some of the system peripherals are also used on AT91SAM9260 and AT91SAM9261. The new SAM9-specific register bits have also been defined.

+0100 Subject: [ARM] 3951/1: AT91: Rename user peripheral header files Most of the AT91RM9200 user peripherals are also integrated into the Atmel SAM9 range of processors. This patch renames the headers from at91rm9200_xx.h to at91_xx.h to indicate they're not at91rm9200-specific. The new SAM9-specific registers and register bits have also been defined.

2006 17:16:43 +0100 Subject: [ARM] 3954/1: AT91: Update drivers for new headers This patch updates the drivers (and other files) which include the hardware headers. This fixes the breakage introduced in patches 3950/1 and 3951/1 (those patches were getting big). The AVR32 architecture uses the same serial driver and had its own copy of at91rm9200_pdc.h. Renamed it to at91_pdc.h Signed-off-by: Andrew Victor Signed-off-by: Russell King --- include/asm-arm/arch-at91rm9200/at91rm9200.h | 16 ++++++++++++++++ include/asm-arm/arch-at91rm9200/debug-macro.S | 1 + include/asm-arm/arch-at91rm9200/entry-macro.S | 1 + include/asm-arm/arch-at91rm9200/hardware.h | 10 +++++++++- include/asm-arm/arch-at91rm9200/irqs.h | 2 ++ include/asm-arm/arch-at91rm9200/system.h | 2 ++ include/asm-arm/arch-at91rm9200/uncompress.h | 4 ++-- 7 files changed, 33 insertions(+), 3 deletions(-) (limited to 'include/asm-arm') diff --git a/include/asm-arm/arch-at91rm9200/at91rm9200.h b/include/asm-arm/arch-at91rm9200/at91rm9200.h index a5a86b1ff88..4d51177efdd 100644 --- a/include/asm-arm/arch-at91rm9200/at91rm9200.h +++ b/include/asm-arm/arch-at91rm9200/at91rm9200.h @@ -79,6 +79,22 @@ #define AT91_BASE_SYS 0xfffff000 +/* + * System Peripherals (offset from AT91_BASE_SYS) + */ +#define AT91_AIC (0xfffff000 - AT91_BASE_SYS) /* Advanced Interrupt Controller */ +#define AT91_DBGU (0xfffff200 - AT91_BASE_SYS) /* Debug Unit */ +#define AT91_PIOA (0xfffff400 - AT91_BASE_SYS) /* PIO Controller A */ +#define AT91_PIOB (0xfffff600 - AT91_BASE_SYS) /* PIO Controller B */ +#define AT91_PIOC (0xfffff800 - AT91_BASE_SYS) /* PIO Controller C */ +#define AT91_PIOD (0xfffffa00 - AT91_BASE_SYS) /* PIO Controller D */ +#define AT91_PMC (0xfffffc00 - AT91_BASE_SYS) /* Power Management Controller */ +#define AT91_ST (0xfffffd00 - AT91_BASE_SYS) /* System Timer */ +#define AT91_RTC (0xfffffe00 - AT91_BASE_SYS) /* Real-Time Clock */ +#define AT91_MC (0xffffff00 - AT91_BASE_SYS) /* Memory Controllers */ + +#define AT91_MATRIX 0 /* not supported */ + /* * Internal Memory. */ diff --git a/include/asm-arm/arch-at91rm9200/debug-macro.S b/include/asm-arm/arch-at91rm9200/debug-macro.S index f496b54c4c3..85cdadf2663 100644 --- a/include/asm-arm/arch-at91rm9200/debug-macro.S +++ b/include/asm-arm/arch-at91rm9200/debug-macro.S @@ -12,6 +12,7 @@ */ #include +#include .macro addruart,rx mrc p15, 0, \rx, c1, c0 diff --git a/include/asm-arm/arch-at91rm9200/entry-macro.S b/include/asm-arm/arch-at91rm9200/entry-macro.S index 61a326e9490..57248a79647 100644 --- a/include/asm-arm/arch-at91rm9200/entry-macro.S +++ b/include/asm-arm/arch-at91rm9200/entry-macro.S @@ -11,6 +11,7 @@ */ #include +#include .macro disable_fiq .endm diff --git a/include/asm-arm/arch-at91rm9200/hardware.h b/include/asm-arm/arch-at91rm9200/hardware.h index 9ca4cc9c0b2..d42e310584a 100644 --- a/include/asm-arm/arch-at91rm9200/hardware.h +++ b/include/asm-arm/arch-at91rm9200/hardware.h @@ -16,8 +16,16 @@ #include +#if defined(CONFIG_ARCH_AT91RM9200) #include -#include +#elif defined(CONFIG_ARCH_AT91SAM9260) +#include +#elif defined(CONFIG_ARCH_AT91SAM9261) +#include +#else +#error "Unsupported AT91 processor" +#endif + /* * Remap the peripherals from address 0xFFFA0000 .. 0xFFFFFFFF diff --git a/include/asm-arm/arch-at91rm9200/irqs.h b/include/asm-arm/arch-at91rm9200/irqs.h index 763cb96c418..c0679eaefaf 100644 --- a/include/asm-arm/arch-at91rm9200/irqs.h +++ b/include/asm-arm/arch-at91rm9200/irqs.h @@ -21,6 +21,8 @@ #ifndef __ASM_ARCH_IRQS_H #define __ASM_ARCH_IRQS_H +#include + #define NR_AIC_IRQS 32 diff --git a/include/asm-arm/arch-at91rm9200/system.h b/include/asm-arm/arch-at91rm9200/system.h index 92f36769b2a..053f2e09c1f 100644 --- a/include/asm-arm/arch-at91rm9200/system.h +++ b/include/asm-arm/arch-at91rm9200/system.h @@ -22,6 +22,8 @@ #define __ASM_ARCH_SYSTEM_H #include +#include +#include static inline void arch_idle(void) { diff --git a/include/asm-arm/arch-at91rm9200/uncompress.h b/include/asm-arm/arch-at91rm9200/uncompress.h index ec7811ab0a5..34b4b93fa01 100644 --- a/include/asm-arm/arch-at91rm9200/uncompress.h +++ b/include/asm-arm/arch-at91rm9200/uncompress.h @@ -22,11 +22,11 @@ #define __ASM_ARCH_UNCOMPRESS_H #include +#include /* * The following code assumes the serial port has already been - * initialized by the bootloader.

2006 20:39:18 +0000 Subject: [ARM] Clean up discontigmem support Most architectures have fairly simple discontiguous memory - a simple set of successive regions each containing some memory. These can be described simply as a log2 of their maximum size, along with the base address of the first region and the number of regions. The base address is already described by PHYS_PFN_OFFSET, and the number of regions via the MAX_NUMNODES and the number of online nodes.

Because of the small amount of state in the DSP coprocessor, access to the DSP coprocessor (CP0) is always enabled, and DSP context switching is done unconditionally on every task switch. Access to the iWMMXt coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is first issued, and iWMMXt context switching is done lazily. CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will have iWMMXt support', but boards are supposed to select this config symbol by hand, and at least one pxa27x board doesn't get this right, so on that board, proc-xscale.S will incorrectly assume that we have a DSP coprocessor, enable CP0 on boot, and we will then only save the first iWMMXt register (wR0) on context switches, which is Bad. This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on might have iWMMXt support, and we will enable iWMMXt context switching if it does.' This means that with this patch, running a CONFIG_IWMMXT=n kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt state over context switches, and running a CONFIG_IWMMXT=y kernel on a non-iWMMXt capable CPU will still do DSP context save/restore. These changes should make iWMMXt work on PXA3xx, and as a side effect, enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined), as well as setting and using HWCAP_IWMMXT properly.

For 64-bit divisions that may take more than a hundred cycles in many cases. With 32-bit divisions gcc already use the recyprocal of constant divisors to perform a multiplication, but not with 64-bit divisions. Since the kernel is increasingly relying upon 64-bit divisions it is worth optimizing at least those cases where the divisor is a constant. This is what this patch does using plain C code that gets optimized away at compile time. For example, despite the amount of added C code, do_div(x, 10000) now produces the following assembly code (where x is assigned to r0-r1): adr r4, .L0 ldmia r4, {r4-r5} umull r2, r3, r4, r0 mov r2, #0 umlal r3, r2, r5, r0 umlal r3, r2, r4, r1 mov r3, #0 umlal r2, r3, r5, r1 mov r0, r2, lsr #11 orr r0, r0, r3, lsl #21 mov r1, r3, lsr #11 ... .L0: .word 948328779 .word 879609302 which is the fastest that can be done for any value of x in that case, many times faster than the __do_div64 code (except for the small x value space for which the result ends up being zero or a single bit). The fact that this code is generated inline produces a tiny increase in .text size, but not significant compared to the needed code around each __do_div64 call site this code is replacing. The algorithm used has been validated on a 16-bit scale for all possible values, and then recodified for 64-bit values. Furthermore I've been running it with the final BUG_ON() uncommented for over two months now with no problem. Note that this new code is compiled with gcc versions 4.0 or later. Earlier gcc versions proved themselves too problematic and only the original code is used with them.

The error crept in because the physical location of the LEDs has the Disk 2 LED *above* the Disk 1 LED. Thanks to Gordon Farquharson for reporting this.

The iop342 processor replaces the SAS controller with a second Xscale core for dual core embedded applications. The iop341 processor is the single core version of iop342.

Then commit 5047f09b56d0bc3c21aec9cb16de60283da645c6 incorrectly reverted change from commit ff10952a547dad934d9ed9afc5cf579ed1ccb53a (bad dwmw2) and the problem recently resurfaced. Because the third argument to __bug() is never used anyway, RMK suggested getting rid of it entirely instead of readding #include which this patch does.
