* ARM: OMAP2: Clock: Add OMAP3 DPLL autoidle functionsPaul Walmsley2008-07-034-30/+371
| | | | | | | | | | | | | | | | This patch adds support for DPLL autoidle control to the OMAP3 clock framework. These functions will be used by the noncore DPLL enable and disable code - this is because, according to the CDP code, the DPLL autoidle status must be saved and restored across DPLL lock/bypass/off transitions. N.B.: the CORE DPLL (DPLL3) has three autoidle mode options, rather than just two. This code currently does not support the third option, low-power bypass autoidle.

* ARM: OMAP: Add OMAP chip type structure; clean up mach-omap2/id.cPaul Walmsley2008-07-031-27/+168
| | | | | | | | | | | | | | | | | | | | | | Add a new OMAP chip identification interface, omap_chip_id. omap_chip_id is a structure which contains one bit for each OMAP2/3 CPU type, and on 3430, ES level. For example, the CHIP_IS_OMAP2420 bit is set in omap_chip at boot on an OMAP2420. On OMAP3430ES2, both CHIP_IS_OMAP3430 and CHIP_IS_OMAP3430ES2 bits are set. omap_chip is set in mach-omap2/id.c by _set_omap_chip(). Other code should use the omap_chip_is() function to test against omap_chip. Also, clean up id.c by splitting some code out of omap_check_revision() into its own function, _set_system_rev(); and converting some debug printk()s into pr_debug(). Second revision.

* ARM: OMAP: CLKFW: Initial debugfs support for omap clock frameworkHiroshi DOYU2008-07-031-36/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | debugfs can provide the infrastructure to trace the dependencies of clock tree hierarchy quite visibly. This patch enables to keep track of clock tree hierarchy and expose their attributes under each clock directry as below: omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/ /debug/clock/omap_32k_fck/ |-- gpt10_fck |-- gpt11_fck |-- gpt1_fck |-- per_32k_alwon_fck | |-- gpio2_fck | |-- gpio3_fck | |-- gpio4_fck | |-- gpio5_fck | |-- gpio6_fck | `-- wdt3_fck |-- ts_fck `-- wkup_32k_fck |-- gpio1_fck `-- wdt2_fck 14 directories omap:~# tree /debug/clock/omap_32k_fck/gpt10_fck/ /debug/clock/omap_32k_fck/gpt10_fck/ |-- flags |-- rate `-- usecount 0 directories, 3 files Although, compared with David Brownell's small patch, this may look bit overkilling, I expect that this debugfs can deal with other PRCM complexities at the same time. For example, powerdomain dependencies can be expressed by using symbolic links of these clocks if powerdomain supports dubgfs as well.

* ARM: OMAP: DMTimer: Use posted modeRichard Woodruff2008-07-031-42/+151
| | | | | | | | | | | | | | | | This patch adds the use of write posting for the timer. Previously, every write could lock the requestor for almost 3x32KHz cycles. This patch only synchronizes before writes and reads instead of after them and it does it on per register basis. Doing it this way there is some chance to hide some of the sync latency. It also removes some needless reads when non-posted mode is there. With out this fix the read/writes take almost 2% CPU load @500MHz just waiting on tick timer registers. Also define new 34xx only registers. Signed-off-by: Richard Woodruff <r-woodruff2@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a system where there are no hot pluggable cpus "additional_cpus" is still set to -1 at the point where we call per_cpu_scan_finalize(). If we didn't find an SRAT table and so pick the default "32" for the number of cpus, when we get to: high_cpu = min(high_cpu + reserve_cpus, NR_CPUS); we will end up initializing for just 31 cpus ... and so we will die horribly when bringing up cpu#32.

Kernel doesn't panic when calling it at the first time. If just say because of nr_cpu_ids, that's not right. By checking the source code, I found that function do_boot_cpu is the culprit. Consider below call chain: _cpu_up=>__cpu_up=>smp_ops.cpu_up=>native_cpu_up=>do_boot_cpu. So do_boot_cpu is called in the end. In do_boot_cpu, if boot_error==true, cpu_clear(cpu, cpu_possible_map) is executed. So later on, when _cpu_up calls __raw_notifier_call_chain at the second time to report CPU_UP_CANCELED, because this cpu is already cleared from cpu_possible_map, get_cpu_sysdev returns NULL. Many resources are related to cpu_possible_map, so it's better not to change it. Below patch against 2.6.26-rc7 fixes it by removing the bit clearing in cpu_possible_map.
