* x86: Add virtualization time sync supportHauke Mehrtens2023-08-151-0/+5
| | | | | | | | | | | | | This compiles the CONFIG_PTP_1588_CLOCK support into the kernel binary and activates the drivers for KVM and VMware which allow syncing the host time with the VM when OpenWrt is running in a VM. With this change the CONFIG_HYPERV_UTILS driver is now build into the kernel, because it depends on the PTP framework being compiled in. CONFIG_HYPERV_UTILS was build as a module, but not packages before. Fixes: #13277 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> (cherry picked from commit 54d470ed0ecaff9e8084c013ddbc95e8afc3ab42)
* x86: Activate CONFIG_PCIEASPMHauke Mehrtens2023-08-151-0/+5
| | | | | | | | | | This activates PCI Express ASPM control in Linux. Without this option it is completely controlled by the BIOS, now Linux will take over and apply some workarounds if needed. Fixes: #13248 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> (cherry picked from commit ff71035751bf440401b4bbc32e0b61ba11178234)
* x86: set CONFIG_X86_AMD_PLATFORM_DEVICEJohn Audia2023-07-081-1/+1
| | | | | | | Needed by AMD processors using Carrizo and later chipsets Signed-off-by: John Audia <therealgraysky@proton.me> (cherry picked from commit 946100ba4128dbee8faf3c03afb692bca74d75fa)
* x86/64: Enable IOMMU_V2 support for later CPUsPhilip Prindeville2023-06-081-1/+1
| | | | | | | Support newer IOMMU_V2 on AMD platforms, useful for DPDK and KVM. Signed-off-by: Philip Prindeville <philipp@redfish-solutions.com> (cherry picked from commit 1eb02ce3254ef6f115640df8ac470574d6903588)
* kernel: Move CONFIG_DRM_XEN_FRONTEND to generic configurationHauke Mehrtens2022-12-231-1/+0
| | | | | | | The CONFIG_DRM_XEN_FRONTEND configuration symbol is also used by the layerscape target, move it to the generic kernel configuration. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* x86: enable PINCTRL for all Intel platformXiaopo Zhang2022-11-201-8/+8
| | | | | | Enable Intel PINCTRL for all platform on both 32 bit and 64 bit target. Signed-off-by: Xiaopo Zhang <xiaopoz@proton.me>
* x86/64: enable Intel PINCTRL in 64bit targetXiaopo Zhang2022-11-201-7/+8
| | | | | | | | | | | | Intel PINCTRL is not enable in the 64bit build, while it is enabled in the x86/general target, which disables the ability of controlling GPIO in the 64 bit build. This commit copies the corresponding part of x86/general config, since it is already there, so it should be fine to enable the same settings here. Signed-off-by: Xiaopo Zhang <xiaopoz@proton.me>
* kernel: Move some IOMMU options to genericHauke Mehrtens2022-09-241-2/+1
| | | | | | | | | | | | This adds some missing IOMMU related options for x86/64 and moves some of them to generic for all targets. On x86 IOMMU_DEFAULT_DMA_LAZY is used by default, on all other platforms IOMMU_DEFAULT_DMA_STRICT is the default. we just follow the default kernel configuration here. Fixes: 8fea4a102ccd ("x86/64: enable IOMMU support") Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* x86/64: enable IOMMU supportNicola Corna2022-09-211-0/+19
| | | | | | | | | | | Enable IOMMU support for Intel and AMD x86 platforms. With this, when the vfio module is present, physical PCI devices can be passed to VMs, for example with `qemu-system-x86_64 -device vfio-pci,host=05:00.0 ...`. IOMMU support increases the kernel size by a small amount (~370KB, from 5239840 B to 5611200 B, a ~7% increase in size). Signed-off-by: Nicola Corna <nicola@corna.info>
* kernel: Activate CONFIG_GPIOLIB in generic configurationHauke Mehrtens2022-08-101-1/+0
| | | | | | | | All targets expect the malta target already activate the CONFIG_GPIOLIB option. Move it to generic kernel configuration and also activate it for malta. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: 5.15: x86-64: enable CONFIG_SLSRui Salvaterra2022-06-271-0/+1
| | | | | | | | Starting with GCC 12, we have the possibility of mitigating straight-line speculation vulnerabilities in x86-64 targets. Make it so. Reported-by: Stefan Lippers-Hollmann <s.l-h@gmx.de> Signed-off-by: Rui Salvaterra <rsalvaterra@gmail.com>
* generic: enable CRYPTO_LIB_BLAKE2S[_X86|_ARM]Tomasz Maciej Nowak2022-06-241-0/+2
| | | | | | | | | | | | This is now built-in, enable so it won't propagate on target configs. Link: https://lkml.org/lkml/2022/1/3/168 Fixes: 79e7a2552e89 ("kernel: bump 5.15 to 5.15.44") Fixes: 0ca93670693b ("kernel: bump 5.10 to 5.10.119") Signed-off-by: Tomasz Maciej Nowak <tmn505@gmail.com> (Link to Kernel's commit taht made it built-in, CRYPTO_LIB_BLAKE2S[_ARM|_X86] as it's selectable, 5.10 backport) Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

* x86: copy config and patches from 5.10 to 5.15Petr Štetiar2022-03-291-0/+491
So the upcoming changes needed for 5.15 can be reviewed easily. Removing following patches backported from 5.15: * 101-v5.15-mfd-lpc_ich-Enable-GPIO-driver-for-DH89xxCC.patch * 102-v5.15-platform-x86-add-meraki-mx100-platform-driver.patch Removed upstreamed patch `300-pcengines_apu1_led.patch` in commit 1b40faf7e4ab ("leds: apu: extend support for PC Engines APU1 with newer firmware") Signed-off-by: Petr Štetiar <ynezz@true.cz>
