I cannot find nowhere ISA .Just is nowhere in my kernel. Where can I find it?
Also do I need GPIO, I2O, I2C, HID, SPI, SFI, I2C-HID etc?
Sorry but I am very noob on Linux Kernel configuration and all this seams strange and completely unknown on me 
Thanks in advanced

| Going for the best takes a lot of time; starting to at least have all the hardware support needed, check out HCL that Jaglover linked to you. Beyond that, it takes a lot of reading and configuring to optimize it; or you can trust someone else to have done that work, a good enough start would be to use a kernel seed from http://kernel-seeds.org/ |

Thanks for your answers I ticked all as modules. I build the kernel and I show in lsmod what going on. I found Intel Watchdog, MVE, Intel LPC and Intel MEI! I didn't know that my system needs them! So I also need i2c i2o, gpio etc because without them some options are disabled. Sorry but the laptop is new so I don't know his hardware at all
The only that I cannot find is ISA. My system needs isa but I cannot find this option on Bus section
Also I changed the kernel compression to LZ4
Before a lot of years, I was a gentoo user. On my Desktop I use FreeBSD witch is my primary OS and I will never going to change it but I never forgot Gentoo. If I am going to run a Linux, this is Gentoo. I don't like any other distro. Only this. Is the hardest but really the best and the fastest. And I like that acts as BSD.
Everyone used FreeBSD knows that passing the desktop limitation, FreeBSD is just amazing. Amazing ports management, flags, powerfull zfs Filesystem, amazing rc services management.
I really love seeing Gentoo to understand all this beauty and follow it with his own outstanding way

Some options depend on other option selected. Per example there's no point in providing PAE option if you have select a 64bits kernel.
And you can build a kernel with anything set as module, then swap the ones you need to boot as include (mostly harddisk controller). Boot up and you'll see udev/evdev/systemd loading needed modules for your hardware. That will answer your question to what modules my hardware can use.
Some modules will match your hardware need even not list in lspci/lshw... |

All this days I made over 100 kernel configs for customization I set gazillion modules and learned trumendous things.
When I see something that I am not sure if the system needs it, I tick it in any case as buildin (No module). Hopefully they are not too much.
All radio, gps, floppys, pata, atapi etc are disabled. I don't need them. The only I didn't touch because I think is very dangerous is kernel hacking section.
I set everything as modules but I go by sections because kernel is huge!!!
I also found that I need intel_powerclamp
For now.
Ethernet working
Wifi working
Laptop Camera working
Sound working
Backlight, FN keys working
bluetooth semiworking. Scanning see my bluetooth keyboard but don't pair the device
Card-reader / HDMI not tested yet
DVD-drive working
usb working
Intel hd4000 working
Microphone working
Touchscreen not working. It was working when I tried Xubuntu so It must be included in kernel. I tried all the modules but stiil didn't found the right combination.
NFS working. Somewhere I guess has a bug (See here: http://forums-web1.gentoo.org/viewtopic-t-988454.html?sid=29fd586c3f126c43d8cbb4cd806faae2) but is workable.
Also I am not sure about my thermal config.
After sensors-detect on lm_sensor I get:
| Code: | acpitz-virtual-0
Adapter: Virtual device
temp1: +53.0°C (crit = +127.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +52.0°C (high = +87.0°C, crit = +105.0°C)
Core 0: +48.0°C (high = +87.0°C, crit = +105.0°C)
Core 1: +49.0°C (high = +87.0°C, crit = +105.0°C)
Core 2: +48.0°C (high = +87.0°C, crit = +105.0°C)
Core 3: +51.0°C (high = +87.0°C, crit = +105.0°C)
|
Shouldn't the list be bigger with hdd's etc?
I tried all modules but sensors-detect found that my laptop don't have this modules.
I have a lot to go because also sound is not working properly but my Gentoo box is starting to shine

Yes but in two conditions : your sensor is support by lm_sensors and the module for the sensors is built.
https://en.wikipedia.org/wiki/Lm_sensors#Example_output
For your hdd -> emerge hddtemp && hddtemp /dev/sd?
But again, if your hdd is support or smart enable. |

Ok. I can get hdd temp with hddtemp tool
But with lm_sensors:
| Code: | ember@gentoo ~/Desktop $ sudo sensors-detect
Password:
# sensors-detect revision 6170 (2013-05-20 21:25:22 +0200)
# System: LENOVO 20211 [Lenovo IdeaPad P400 Touch] (laptop)
# Board: LENOVO INVALID
This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): y

Some Super I/O chips contain embedded sensors. We have to write to

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Intel Panther Point (PCH)
Next adapter: i915 gmbus ssc (i2c-0)
Do you want to scan it? (yes/NO/selectively): y
Next adapter: i915 gmbus vga (i2c-1)
Do you want to scan it? (yes/NO/selectively): y
Next adapter: i915 gmbus panel (i2c-2)
Do you want to scan it? (yes/NO/selectively): y
Next adapter: i915 gmbus dpc (i2c-3)
Do you want to scan it? (yes/NO/selectively): y
y
Next adapter: i915 gmbus dpb (i2c-4)
Do you want to scan it? (yes/NO/selectively): y
Next adapter: i915 gmbus dpd (i2c-5)
Do you want to scan it? (yes/NO/selectively): y
Next adapter: DPDDC-B (i2c-6)
Do you want to scan it? (YES/no/selectively): y
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
Do you want to overwrite /etc/conf.d/lm_sensors? Enter s to specify other file name?
(yes/NO/s): y
Done.
You should now start the lm_sensors service to load the required
kernel modules.
ember@gentoo ~/Desktop $ sudo /etc/init.d/lm_sensors start
* Caching service dependencies ... [ ok ]
* MODULE_0 is not set in /etc/conf.d/lm_sensors, try running sensors-detect
* ERROR: lm_sensors failed to start |
Looks like a module is not loaded but I don't know which. I load all of them as modules and none come up

Simply because none would do the work.
It sadly mean your sensors aren't support, you can look at confirmation there http://www.lm-sensors.org/wiki/Devices |

Yes but it was working with other distros as far as I remember. Also I don't know what sensor the laptop has.

This is the exact driver.
| Code: | HID Multitouch panels (HID_MULTITOUCH)
CONFIG_HID_MULTITOUCH:
Generic support for HID multitouch panels.
Say Y here if you have one of the following devices:
- 3M PCT touch screens
- ActionStar dual touch panels
- Atmel panels
- Cando dual touch panels
- Chunghwa panels
- CVTouch panels
- Cypress TrueTouch panels
- Elan Microelectronics touch panels
- Elo TouchSystems IntelliTouch Plus panels
- GeneralTouch 'Sensing Win7-TwoFinger' panels
- GoodTouch panels
- Hanvon dual touch panels
- Ilitek dual touch panels
- IrTouch Infrared USB panels
- LG Display panels (Dell ST2220Tc)
- Lumio CrystalTouch panels
- MosArt dual-touch panels
- Panasonic multitouch panels
- PenMount dual touch panels
- Perixx Peripad 701 touchpad
- PixArt optical touch screen
- Pixcir dual touch panels
- Quanta panels
- eGalax dual-touch panels, including the Joojoo and Wetab tablets
- SiS multitouch panels
- Stantum multitouch panels
- Touch International Panels
- Unitec Panels
- Wistron optical touch panels
- XAT optical touch panels
- Xiroku optical touch panels
- Zytronic touch panels
If unsure, say N.
To compile this driver as a module, choose M here: the
module will be called hid-multitouch.
Symbol: HID_MULTITOUCH [=y]
Type : tristate
Prompt: HID Multitouch panels
Location:
-> Device Drivers
-> HID support
-> HID bus support (HID [=y])
-> Special HID drivers
Defined at drivers/hid/Kconfig:429
Depends on: INPUT [=y] && HID [=y]

My laptop is Lenovo P400 touchscreen. I don't know the driver of the touchscreen and I nowhere found informations. Just I load all modules and I show in lsmod that my touscreen worked with this module. The laptop is new and I didn't know exact all hardware. Now I am learning it.
