* | [MIPS] Make I/O helpers more customizableAtsushi Nemoto2006-03-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Move ioswab*() and __mem_ioswab*() to mangle-port.h. This gets rid of CONFIG_SGI_IP22 from include/asm-mips/io.h. 2. Pass a virtual address to *ioswab*(). Then we can provide mach-specific *ioswab*() and can do every evil thing based on its argument. It could be useful on machines which have regions with different endian conversion scheme. 3. Call __swizzle_addr*() _after_ adding mips_io_port_base. This unifies the meaning of the argument of __swizzle_addr*() (always virtual address). Then mach-specific __swizzle_addr*() can do every evil thing based on the argument.

* [MIPS] Sibyte: Fix race in sb1250_gettimeoffset().Ralf Baechle2006-03-18
| | | | | | | | | | | | | | | | | | | | | | | From Dave Johnson <djohnson+linuxmips@sw.starentnetworks.com>: sb1250_gettimeoffset() simply reads the current cpu 0 timer remaining value, however once this counter reaches 0 and the interrupt is raised, it immediately resets and begins to count down again. If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday() after the timer has reset but prior to cpu 0 processing the interrupt and taking write_seqlock() in timer_interrupt() it will return a full value (or close to it) causing time to jump backwards 1ms. Once cpu 0 handles the interrupt and timer_interrupt() gets far enough along it will jump forward 1ms. Fix this problem by implementing mips_hpt_*() on sb1250 using a spare timer unrelated to the existing periodic interrupt timers. It runs at 1Mhz with a full 23bit counter. This eliminated the custom do_gettimeoffset() for sb1250 and allowed use of the generic fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.

* [MIPS] Work around bad code generation for <asm/io.h>.Ralf Baechle2006-03-18
| | | | | | | | | If a call to set_io_port_base() was being followed by usage of mips_io_port_base in the same function gcc was possibly using the old value due to some clever abuse of const. Adding a barrier will keep the optimization and result in correct code with latest gcc. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

* [MIPS] SMP: Fix initialization order bug.Ralf Baechle2006-02-27
| | | | | | | | | | | | | | A recent change requires cpu_possible_map to be initialized before smp_sched_init() but most MIPS platforms were initializing their processors in the prom_prepare_cpus callback of smp_prepare_cpus. The simple fix of calling prom_prepare_cpus from one of the earlier SMP initialization hooks doesn't work well either since IPIs may require init_IRQ() to have completed, so bit the bullet and split prom_prepare_cpus into two initialization functions, plat_smp_setup which is called early from setup_arch and plat_prepare_cpus called where prom_prepare_cpus used to be called.

* [PATCH] madvise MADV_DONTFORK/MADV_DOFORKMichael S. Tsirkin2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | Currently, copy-on-write may change the physical address of a page even if the user requested that the page is pinned in memory (either by mlock or by get_user_pages). This happens if the process forks meanwhile, and the parent writes to that page. As a result, the page is orphaned: in case of get_user_pages, the application will never see any data hardware DMA's into this page after the COW. In case of mlock'd memory, the parent is not getting the realtime/security benefits of mlock. In particular, this affects the Infiniband modules which do DMA from and into user pages all the time. This patch adds madvise options to control whether memory range is inherited across fork. Useful e.g. for when hardware is doing DMA from/into these pages. Could also be useful to an application wanting to speed up its forks by cutting large areas out of consideration. Signed-off-by: Michael S.

* [MIPS] More uaccess.h fixes with gcc >= 4.0.1.Ralf Baechle2006-02-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Richard Sandiford <richard@codesourcery.com>: This patch caused a miscompilation of the restore_gp_regs() block in restore_sigcontext(). This was in a 32-bit kernel compiled with GCC CVS head. restore_gp_regs() copies 64-bit user fields into 32-bit variables, and in this combination, the new __get_user_asm_ll32() clobbers too many registers. It says: /* * Get a long long 64 using 32 bit registers. */ { \ __asm__ __volatile__( \ "1: lw %1, (%3) \n" \ "2: lw %D1, 4(%3) \n" \ " move %0, $0 \n" \ "3: .section .fixup,\"ax\" \n" \ "4: li %0, %4 \n" \ " move %1, $0 \n" \ " move %D1, $0 \n" \ " j 3b \n" \ " .previous \n" \ " .section __ex_table,\"a\" \n" \ " " __UA_ADDR " 1b, 4b \n" \ " " __UA_ADDR " 2b, 4b \n" \ " .previous \n" \ : "=r" (__gu_err), "=&r" (val) \ : "0" (0), "r" (addr), "i" (-EFAULT)); \ } and this requires val (%1) to be a 64-bit value. In the case I saw, gcc was using $3 for the 32-bit val, and wasn't expecting $4 to be clobbered. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | I've noticed that PCI clock was incorrectly reported as 66 MHz while being mere 33 MHz on RBTX4937 board -- this was due to the different encoding of the PCI divisor field in CCFG register between TX4927 and TX4937 chips...
