User:Pietinger/Experimental/Manual Configuring Kernel Version 6.10
Even though this page is in the user namespace, corrections and additions are much appreciated! This is simply wiki policy, this page can be moved to the main wiki as soon as it achieves critical mass more.
Manual Configuring Kernel Version 6.10
Normally I do not recommend switching to a new major version of the kernel immediately, but to wait for two, three or four minor versions first. I did this this time too, because no new features are relevant for me. But if you have a high-end server with a very high load, then X86_POSTED_MSI (*) could be interesting for you. That's why I looked at the configuration of 6.10.
Notes for 6.10
A good overview of everything new in 6.10 can be found here:

Many options from Device Drivers -> Graphics support have been moved one level lower to :
Device Drivers --->
Graphics support --->
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
One of the newly added options is:
Device Drivers --->
Graphics support --->
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
[ ] Display a user-friendly message when a kernel panic occurs (NEW)
You are welcome to try to activate them ... but it will disappear again immediately after you have activated this option (this is a must) - because both cannot be activated at the same time:
Device Drivers --->
Graphics support --->
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
[*] Enable legacy fbdev support for your modesetting driver
Upgrade from 6.6
Please read:
- User:Pietinger/Experimental/Manual_Configuring_Kernel_Version_6.7#Upgrade_from_6.6
- User:Pietinger/Experimental/Manual_Configuring_Kernel_Version_6.8#Upgrade_from_6.7
- User:Pietinger/Experimental/Manual_Configuring_Kernel_Version_6.9#Upgrade_from_6.8
and then the following chapter.
Upgrade from 6.9
I took over all default values with <return> when I did the make oldconfig. Here is a possible list (I have left out - as always - all new modules for some new hardware; if you have one of them, enable it):
Enable BPF Just In Time compiler (BPF_JIT) [N/y/?] (NEW) 1. Enable smaller-sized data structures for core (BASE_SMALL) [N/y/?] (NEW) 2. Enable MSI and MSI-x delivery by posted interrupts (X86_POSTED_MSI) [N/y/?] (NEW) 3. Kprobes (KPROBES) [N/y/?] (NEW) 4. Use HMAC and encrypted transactions on the TPM bus (TCG_TPM2_HMAC) [Y/n/?] (NEW) 5. Enable DisplayPort CEC-Tunneling-over-AUX HDMI support (DRM_DISPLAY_DP_AUX_CEC) [N/y/?] (NEW) DRM DP AUX Interface (DRM_DISPLAY_DP_AUX_CHARDEV) [N/y/?] (NEW) ACPI Quickstart button driver (ACPI_QUICKSTART) [N/y/?] (NEW) 6. Enable memory allocation profiling (MEM_ALLOC_PROFILING) [N/y/?] (NEW)
Remarks
1. We only get this question because we have already activated CONFIG_EXPERT
2. We only get this question because we have already activated IRQ_REMAP
3. There is a discrepancy between the default here and the default setting when you install with the default .config from make defconfig. I have adopted “N”o here. (see next chapter)
4. I only got this question because I have already activated TCG_TPM (because of IMA)
5. Enable it only if you need it.
6. I have adopted the default. You can activate this if you are looking for a memory leak.
New Installation
If you want to activate X86_POSTED_MSI you must first activate IRQ_REMAP; in this order:
Device Drivers --->
[*] IOMMU Hardware Support --->
[*] Support for Interrupt Remapping
Processor type and features --->
[*] Enable MSI and MSI-x delivery by posted interrupts
Check whether you really want this (I used the default when transferring using “make oldconfig”; see previous chapter) - As always, the <Help> is really very informative:
General architecture-dependent options --->
[?] Kprobes
Be aware that many settings for the graphics can now be found here (we will have to update some wiki pages in the future):
Device Drivers --->
Graphics support --->
<*> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
...
# I dont run in a VM
< > Virtio GPU driver
