| * MIPS: Loongson: Fix random early boot hangAaro Koskinen2013-06-211-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Loongson boards (e.g. Lemote FuLoong mini-PC) use ISA/southbridge device (CS5536 general purpose timer) for the timer interrupt. It starts running early and is already enabled during the PCI configuration, during which there is a small window in pci_read_base() when the register access is temporarily disabled. If the timer interrupts at this point, the system will hang. Fix this by adding a fixup that keeps the register access always enabled. The hang the patch fixes usually looks like this: [ 0.844000] pci 0000:00:0e.0: [1022:2090] type 00 class 0x060100 [ 0.848000] pci 0000:00:0e.0: reg 10: [io 0xb410-0xb417] [ 0.852000] pci 0000:00:0e.0: reg 14: [io 0xb000-0xb0ff] [ 0.856000] pci 0000:00:0e.0: reg 18: [io 0xb380-0xb3bf] [ 28.140000] BUG: soft lockup - CPU#0 stuck for 23s!

* | cpufreq: rename index as driver_data in cpufreq_frequency_tableViresh Kumar2013-06-041-1/+2
|/ | | | | | | | | | | | | | | | | The "index" field of struct cpufreq_frequency_table was never an index and isn't used at all by the cpufreq core. It only is useful for cpufreq drivers for their internal purposes. Many people nowadays blindly set it in ascending order with the assumption that the core will use it, which is a mistake. Rename it to "driver_data" as that's what its purpose is. All of its users are updated accordingly.

* MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jumpWu Zhangjin2010-04-301-1/+19
| | | | | | | | | | | | | | | | | | | | | | The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

* MIPS: Loongson: Cleanup the halt and poweroff actionWu Zhangjin2010-02-271-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In the old source code, I have let halt and poweroff do the same action, but in reality, they have different meanings. As the manpage of shutdown shows: -r Reboot after shutdown. -H Halt action is to halt or drop into boot monitor on systems that support it. -P Halt action is to turn off the power. and in the real world, some machines(e.g. NAS) did not provide a power button and the shutdown works as reset, so, we need to provide a mechanism to let the users turn off the power safely without breaking the system, such a mechanism is "halt", which only put the system into a dead loop or a power-save mode and print some information to the screen to tell the users to turn off the power safely. $ shutdown -hH now /* loongson_halt, not turn off the power */ $ shutdown -hP now /* loongson_poweroff, work as poweroff */ Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Tested-by: Liu Shiwei <liushiwei@gmail.com> Cc: Liu Shiwei <liushiwei@gmail.com> Cc: linux-mips <linux-mips@linux-mips.org> Patchwork: http://patchwork.linux-mips.org/patch/883/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
