From b729c09a452a659cdf4d29d83943aa798c5c4ffc Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 7 Nov 2006 21:00:22 +0000 Subject: [PATCH 01/76] [ARM] Improve reliability of APM-emulation suspend The APM emulation can sometimes cause suspend to fail to work due to apparantly waiting for some process to acknowledge an event when it actually has already done so. We re-jig the event handling to work around this behaviour.

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.

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.

Nov 2006 14:34:53 +0100 Subject: [PATCH 26/76] [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: [PATCH 27/76] [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.

+0000 Subject: [PATCH 30/76] [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. If we then supply the log2 of their maximum size, all the other discontigmem macros can move into generic code. There is one exception: lh7a40x seems to have a more complicated setup; this is left alone.

These are mainly to replace references to ARCH_AT91RM9200 and ARCH_AT91SAM9261 with the common/generic ARCH_AT91. That way we don't need to mention every specific AT91 processor explicitly. Also adds the configuration option for AT91SAM9260-EK and AT91SAM9261-EK boards.

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.

Bits 0 to 31 of the count are provided by the hardware while bits 32 to 62 are stored in memory. The top bit in memory is used to synchronize with the hardware count half-period. When the top bit of both counters (hardware and in memory) differ then the memory is updated with a new value, incrementing it when the hardware counter wraps around. Because a word store in memory is atomic then the incremented value will always be in synch with the top bit indicating to any potential concurrent reader if the value in memory is up to date or not wrt the needed increment.

Dec 2006 02:59:39 +0100 Subject: [PATCH 70/76] [ARM] 3995/1: iop13xx: add iop13xx support The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz PCI-X interface, a x8 PCI-Express interface, and other peripherals to form a system-on-a-chip RAID subsystem engine. 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. This patch supports the two Intel customer reference platforms iq81340mc for external storage and iq81340sc for direct attach (HBA) development. The developer's manual is available here: ftp://download.intel.com/design/iio/docs/31503701.pdf Changelog: * removed virtual addresses from resource definitions * cleaned up some unnecessary

It seems that stddef.h was always included indirectly in most cases, and that issue was properly fixed a while ago. 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.
