Works like a charm, yes! Including suspend and hibernate (when @Imh69 gave us the first report about a working solution I had this slight worry that ACPI would not be working but that was only the first approach I guess). Many thanks indeed from me too.

I did think that @JerryXiao or @taz-007 might want to use the change I suggested on 2022-05-20 to the two “make” lines in PKGBUILD. As this hasn’t happened I made these changes manually during my update. Therefore I can’t say if the unaltered version would still have warned about a compiler mismatch on my system.

nvidia-340xx-dkms 340.108-30 on 5.18.0-arch1-1 works fine. Thank you very much.

@poluyan I was able to get a clean compilation using the @Viterzgir patch for 5.18 kernel, with 2 modifications. First one to "fix" the error in nv-vm.c

-    return pci_map_sg(dev, sg, 1, PCI_DMA_BIDIRECTIONAL);
+    return dma_map_sg(&dev->dev, sg, 1, DMA_BIDIRECTIONAL);
-    pci_unmap_sg(dev, sg, 1, PCI_DMA_BIDIRECTIONAL);
+    dma_unmap_sg(&dev->dev, sg, 1, DMA_BIDIRECTIONAL);

ERROR: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol 'acpi_fetch_acpi_dev'

Subject: [PATCH] Buildfix NVIDIA 470.103.01 for Linux 5.18-rc2

acpi_bus_get_device was removed and its trivial replacement acpi_fetch_acpi_dev
is GPL-exported, so just disable ACPI support as I don't want to deal with it.

-#if defined(NV_LINUX_ACPI_EVENTS_SUPPORTED)
+#include <linux/version.h>
+#if defined(NV_LINUX_ACPI_EVENTS_SUPPORTED) && (LINUX_VERSION_CODE < KERNEL_VERSION(5, 18, 0))

I havent check if the module is properly working using this, yet.

@calvinh, no. I have an error using this patch. Something is wrong with pci_map_sg, pci_unmap_sg and PCI_DMA_BIDIRECTIONAL. I can't find extra patch for this error fix. Please share if you find it.

Anybody has success using Viterzgir's patch?

Thanks so much for maintaining this!

I was able to avoid the message about a compiler mismatch and the subsequent non-zero exit status of the dkms install by changing PKGBUILD. I added a setting to the environment variable CC to the calls to make, turning

make ...

to

env CC=gcc make ...

for both lines. Maybe the maintainers would like to incorporate that change?

@holyArch thanks a lto, works for me witk 5.15.38-1-lts

Build fails when upgrading to 5.17.5-arch1-2.

sudo env IGNORE_CC_MISMATCH=1 dkms install -m nvidia -v 340.108 -k 5.17.5-arch1-2 did the trick.
