old sequence: size ==> >4G ==> point to RAM changed to: >4G ==> point to RAM ==> size some bios even leave aper to unclear, so check size at last. To avoid reporting: Node 0: Aperture @ 4a42000000 size 32 MB Aperture too small (32 MB) with this change we will get: Node 0: Aperture @ 4a42000000 size 32 MB Aperture beyond 4G. Ignoring.

Some consumer ICH9 boards (such as the Abit IP35 Pro) do not provide a BIOS option for enabling the HPET. The same ICH workaround used for 6,7,8 can be applied to 9. Here I enable the only PCI id that was visible on my system. I have confirmed the HPETs work both from userspace and as a clocksource for the running kernel (2.6.24 here) after applying this patch.

Without this patch the linker will generate a section named .sched.text.1 which is unexpected. This is because the gcc generated section has "ax" but the assembler usage of .sched.text lacks the "ax" specifier. It would be better to have a definition we could use from assembler code but I did not find a suitable header file for it.

The existing Geode GPIO API only allows for updating one GPIO at once. There are instances where users want to update multiple GPIOs at once. With the current API, they are given two choices; either ignore the GPIO API: outl(0xc000, gpio_base + GPIO_OUTPUT_VAL); outl(0xc000, gpio_base + GPIO_OUTPUT_ENABLE); Alternatively, call each GPIO update separately: geode_gpio_set(14, GPIO_OUTPUT_VAL); geode_gpio_set(15, GPIO_OUTPUT_VAL); geode_gpio_set(14, GPIO_OUTPUT_ENABLE); geode_gpio_set(15, GPIO_OUTPUT_ENABLE); Neither are desirable. This patch changes the GPIO API to allow for setting of multiple GPIOs at once; rather than being passed an integer, we pass a bitmask and provide a translation function. The above code would now look like this: geode_gpio_set(geode_gpio(14)|geode_gpio(15), GPIO_OUTPUT_VAL); geode_gpio_set(geode_gpio(14)|geode_gpio(15), GPIO_OUTPUT_ENABLE); Since there are no upstream users of the GPIO API yet (afaik), best to change this now. This also adds a bit of sanity checking; it is no longer possible to use a GPIO above 28. Note the semantics of geode_gpio_isset() have changed: geode_gpio_isset(geode_gpio(3)|geode_gpio(4), ...) will only return true iff both GPIOs are set.

I found a small bug of NUMA emulation code for x86_64. (CONFIG_NUMA_EMU) If machine is non-NUMA, find_node_by_addr() should return NUMA_NO_NODE, but current implementation code returns existent maximum NUMA node number + 1. This is not existent NUMA node number. However, this behaviour does not affect NUMA emulation fortunately, because acpi_fake_nodes() that is caller of find_node_by_addr() gets pxm (proximity domain) by node_to_pxm() from non-existent NUMA node number that was returned by find_node_by_addr(). node_to_pxm() returns PXM_INVAL that means illegal or non-existent NUMA node number.

The function __cpufreq_set_policy in file drivers/cpufreq/cpufreq.c has a very obvious error: if (policy->min > data->min && policy->min > policy->max) { ret = -EINVAL; goto error_out; } This condtion statement is wrong because it returns -EINVAL only if policy->min is greater than policy->max (in this case, "policy->min > data->min" is true for ever.). In fact, it should return -EINVAL as well if policy->max is less than data->min. The correct condition should be: if (policy->min > data->max || policy->max < data->min) { The following test result testifies the above conclusion: Before applying this patch: [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 2394000 1596000 [root@yangyi-dev /]# echo 1596000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1596000 [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 1596000 [root@yangyi-dev /]# echo "2000000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq -bash: echo: write error: Invalid argument [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 1596000 [root@yangyi-dev /]# echo "0" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1596000 [root@yangyi-dev /]# echo "1595000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1596000 [root@yangyi-dev /]# After applying this patch: [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 2394000 1596000 [root@yangyi-dev /]# echo 1596000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1596000 [root@yangyi-dev /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 1596000 [root@localhost /]# echo "2000000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq -bash: echo: write error: Invalid argument [root@localhost /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 1596000 [root@localhost /]# echo "0" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq -bash: echo: write error: Invalid argument [root@localhost /]# echo "1595000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq -bash: echo: write error: Invalid argument [root@localhost /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1596000 [root@localhost /]# echo "1596000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@localhost /]# echo "2394000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq [root@localhost /]# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 2394000 [root@localhost /] Signed-off-by: NYi Yang <yi.y.yang@intel.com> Signed-off-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

when MTRRs are not covering the whole e820 table, we need to trim the RAM and need to update e820. reuse some code on 64-bit as well. here need to add early_get_cap and use it in early_cpu_detect, and move mtrr_bp_init early. The code successfully trimmed the memory map on Justin's system: from: [ 0.000000] BIOS-e820: 0000000100000000 - 000000022c000000 (usable) to: [ 0.000000] modified: 0000000100000000 - 0000000228000000 (usable) [ 0.000000] modified: 0000000228000000 - 000000022c000000 (reserved) According to Justin it makes quite a difference: | When I boot the box without any trimming it acts like a 286 or 386, | takes about 10 minutes to boot (using raptor disks).
