* x86: Use kernel specific subtarget configurationsHauke Mehrtens2019-01-121-436/+0
| | | | | | | | | | This makes it possible to use different sub target configurations for kernel 4.19 for example. To support kernel 4.9 and kernel 4.14 with the same configuration file already needed some extra work this will not be needed for kernel 4.19 any more.

* kernel: enable memory compactionFelix Fietkau2018-10-091-0/+1
| | | | | | | | | | | Compaction is the only memory management component to form high order (larger physically contiguous) memory blocks reliably. The page allocator relies on compaction heavily and the lack of the feature can lead to unexpected OOM killer invocations for high order memory requests. You shouldn't disable this option unless there really is a strong reason for it. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Michal Hrusecky <michal.hrusecky@nic.cz>
* x86/64: enable X86_INTEL_LPSS to select PINCTRLMartin Schiller2018-08-251-1/+10
| | | | | | | This makes it possible to use the MCP23S08 i/o expander on x86_64 platforms with linux 4.14. Signed-off-by: Martin Schiller <ms@dev.tdt.de>
* x86: disable CONFIG_EFI_VARSAlif M. Ahmad2018-05-181-1/+1
| | | | | | | | | | Disable CONFIG_EFI_VARS, since it suffers from sysfs limitation (no support for variable longer than 1024 bytes). kmod-fs-efivarfs is the replacement of this, which enables mounting efivarfs file system and doesn't suffer from 1024 bytes limitation.

* kernel: bump 4.14 to 4.14.11Stijn Tintel2018-01-031-1/+2
| | | | | | | | | | | | | | | Rename unwinder config symbols to match upstream changes. Refresh patches. Update patch that no longer applies: 202-reduce_module_size.patch Also enable CONFIG_PAGE_TABLE_ISOLATION. This feature was backported from 4.15 to the 4.14 stable series. It is enabled by default, so enable it in OpenWrt as well. Compile-tested on x86/64. Runtime-tested on x86/64. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* x86: Add support for kernel 4.14Hauke Mehrtens2017-12-161-4/+32
| | | | | | | | This adds basic support for kernel 4.14, this was tested in qemu only. The subtarget configuration was refresh with kernel 4.14 and the options needed to make it compile on kernel 4.9 were added manually. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* x86: refresh configurationHauke Mehrtens2017-12-161-3/+3
| | | | | | | Just refresh the kernel configuration, some options are removed because they are now in the generic kernel configuration. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* x86: add on-chip thermal sensors and cpuid supportPhilip Prindeville2017-12-161-1/+18
| | | | | | | | | | | Cover temperature sensors for all mainstream 64-bit processors, including AMD 10h and 15h families, Intel iCore, Xeon, Atom, and Via Nano. Also add CPUID support for user-space applications to detect CPU type. Include the on-chip sensors for 64-bit CPU's in the generic profile in case someone builds a 32-bit kernel to run on a Xeon SoC, etc. Signed-off-by: Philip Prindeville <philipp@redfish-solutions.com>

* x86: Fix xen serial console by removing conflicting PATA driverBaptiste Jonglez2017-07-161-1/+0
| | | | | | | | | | | | | | | | | | | | | The Xen serial console has been broken since the xen_domu subtarget was merged in the generic x86 subtarget (commits 1d6879ee and 371b382a). The reason for the broken serial console seems to be an IRQ conflict between the serial console driver and the PATA_LEGACY driver: [ 1.330125] genirq: Flags mismatch irq 8. 00000000 (hvc_console) vs. 00000000 (platform[pata_legacy.4]) [ 1.330134] hvc_open: request_irq failed with rc -16. [ 1.330148] Warning: unable to open an initial console. Just drop the PATA_LEGACY driver from the x86/generic and x86_64 subtargets, since this driver is marked experimental and only supports very old ISA devices anyway. It is still included in the x86/legacy subtarget where it rightfully belongs. Fixes: FS#787 Signed-off-by: Baptiste Jonglez <git@bitsofnetworks.org>
* x86/64: add xen DomU supportBaptiste Jonglez2017-07-161-1/+59
| | | | | | | | | | Xen support for x86/generic was added in 1d6879ee. This commit also enables it for x86/64. This was successfully tested with Xen 4.5, although the serial console is broken in the same way as x86/generic (see FS#787) Signed-off-by: Baptiste Jonglez <git@bitsofnetworks.org>
* x86: Move USB support from subtargets to target configBaptiste Jonglez2017-07-161-9/+0
| | | | | | | | | All x86 subtargets enable USB support, so it makes sense to enable it in the target config instead, to avoid duplication. Also refresh subtarget configs accordingly. Signed-off-by: Baptiste Jonglez <git@bitsofnetworks.org>
* x86: Refresh subtargets kernel configBaptiste Jonglez2017-07-161-14/+2
| | | | | | | | | | | | | | | | | This was done by simply running `make kernel_menuconfig CONFIG_TARGET=subtarget` and then saving without changing any option. Most of the removed options can be explained because they are already present in the target config or in the generic 4.9 config: - PAE-related options, enabled by default on x86 by 961c0eac - LZO-related options, enabled by default since 4.9 As far as I understand the build system, this shouldn't have any user-visible impact, because the build system already merges the various kernel configs during build.

* x86_64: add drivers for Xeon controller hub based GPIOPhilip Prindeville2017-05-251-2/+4

* kernel: Add intel_idle driver to x86_64 buildMichael Marley2017-03-141-0/+1
| | | | | | | | | This driver supports CPU-specific idle features on recent Intel processors. It does not conflict with the ACPI idle driver and that driver will continue to be used for unsupported and non-Intel processors. Signed-off-by: Michael Marley <michael@michaelmarley.com>
* kernel: Add coretemp driver to x86_64 buildMichael Marley2017-03-141-0/+1
| | | | | | | | The x86_64 build already has the k10temp driver for AMD processors built in, so this patch adds the coretemp driver for the same functionality on Intel processors. Signed-off-by: Michael Marley <michael@michaelmarley.com>

* x86_64: Add support for EFI framebuffer (FS#515)Alif M. Ahmad2017-02-211-1/+2
| | | | | | | | | | | | | | | CONFIG_FB_EFI and CONFIG_FB_SIMPLE are needed to display console text on EFI framebuffer. CONFIG_FB_EFI is needed when the kernel is directly launched via EFI shell or EFI startup.nsh script. CONFIG_FB_SIMPLE is needed when launching the kernel via grub2 efi. In this case, grub2 has prepared a gfxterm framebuffer and the kernel just need to use the already prepared grub's gfxterm framebuffer to display console text. Signed-off-by: Alif M.

* x86/64: enable AES-NI support in kernelStijn Tintel2017-01-041-1/+2
| | | | | | | | | | | | | The kernel will detect if the host supports this, so we can just enable it in the kernel config. Tested on an APU2 with AES-NI support and a KVM VM on a Xeon E5520 host without AES-NI support. Throughput over an IPsec tunnel between these 2 hosts increased from ~63Mbps to ~140Mbps. Ciphers: AES_GCM_16_256/PRF_HMAC_SHA2_512/ECP_521. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* x86/64: enable Hyper-V support in the x86_64 kernel configTedaz2016-12-221-1/+32
| | | | | | | | | | | | Enabled Hyper-V network interface card driver, display adapter driver, storage driver, keyboard driver, mouse driver and Hyper-V utility and EFI boot support in the kernel for subtarget x86/64. Convert the img file to vhd by Ubuntu qemu-img, rather than by the buildroot's built-in qemu-img.

* x86: add PATA support to generic and 64 subtargetsAndreas Ziegler2016-11-161-0/+6
| | | | | | | | | | | | PATA support has been removed from x86-generic without any note in LEDE r538. Not including them makes the generated images incompatible with older (and some newer) hardware without any significant gain. Add it back, and also add the same drivers (as far as available) to x86-64.

CONFIG_PCI_LABEL and CONFIG_ATA_PIIX were removed because they were already enabled in x86 platform config 2. CONFIG_ATA_SFF was removed because it was enabled in generic config 3. CONFIG_NLS was removed because it will be selected by CONFIG_PCI_LABEL Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
* x86: enable CPU frequency scalingLucian Cristian2016-08-031-1/+4
