It is certainly better than the regular ACPI timer, but I found that it did not help very much on Haswell+. There is a better, more precise timer than ACPI that apparently did improve things on those systems (but still not perfect): invariant TSC-based timer. Windows 7 supports this but it actually is rarely used in practice. I enabled it in Vista with a test HAL, but it wasn't released because it didn't boot on some systems. 1 Link to comment Share on other sites More sharing options...

I'm a bit confussed. It will support other drivers as well; the next one in my sights is the Process Hacker 2.39 driver. I will also add functions for Intel and AMD drivers, and also other system drivers such as Windows 7 file system drivers (which support TRIM). 2 Link to comment Share on other sites More sharing options...
D.Draker Posted September 8, 2022 Share Posted September 8, 2022 win32 , just wanted to say again and again , your kernel is absolutely fantastic , even with that weird shell issue . All extensions finally work ! No more need to force them. 1 Link to comment Share on other sites More sharing options...
Brickedandroid Posted September 8, 2022 Share Posted September 8, 2022 (edited) @win32 Could you please add the support for the color emojis like in Windows 8.1 and 10? I installed the emoji font file picked from the fully updated Windows 10 computer (you can try download from https://anonfiles.com/U384l078yc/seguiemj_ttf and install it). But outside of Firefox browser, the emojis are displayed only in black and white... Edited September 8, 2022 by Brickedandroid Link to comment Share on other sites More sharing options...
Valvados Posted September 20, 2022 Share Posted September 20, 2022 Interested in getting the Vista EX Kernel installed, I don't have it and I'm testing 2022 games on Vista x64, a couple of them have thrown an error KERNEL32dll. Link to comment Share on other sites More sharing options...

George King Posted September 30, 2022 Share Posted September 30, 2022 @win32 Is there list of functions added to NTOSKRNL.exe? It would be great to see source code too (if available in C), maybe we can add some of them to NTOSKRN8.sys to port more drivers to XP/2003/Vista/7 from newer systems Link to comment Share on other sites More sharing options...

I then added these functions with my own driver (unreleased due to isolated bugs on a small number of configurations while using certain drivers, but otherwise NVIDIA 398 is stable): memcpy_s KeQueryMaximumProcessorCountEx KeQueryLogicalProcessorRelationship strncpy_s _snprintf_s KeQueryUnbiasedInterruptTime (this is still a stub, which relies on the biased interrupt time; lacking time to implement the proper implementation in the driver which grabs the bias value from elsewhere in the shared kernel data iirc) I decided to upload the more complicated function implementations to here: https://github.com/win32ss/win32-api-reversals/tree/main/kernelmode There is also some preliminary work on improving dxgkrnl to use Vulkan with NVIDIA drivers on Vista, and perhaps attempts at WDDM 2.x support in the far off distance.

This is not very relevant to this topic, but one would have to fill in the gaps and add XP/2003 functions in addition to the Vista+ functions for that to work properly. Then perhaps it could work, but there are some other ways in which the kernel side differs (XP has a distinct dxgkrnl, 2000 does not, but most XP graphics drivers were successfully ported to 2000, so perhaps the dxgkrnl functionality was implemented in win32k in 2000). 2 Link to comment Share on other sites More sharing options...

I would love to see more modern drivers for later Windows ported to 2000, but I'm not getting my hopes up. The one, modern, system I bought specifically for 2k use has to use Standard Mode due to the stupid InsydeH2O BIOS and this means most drivers outside of Realtek audio (the main reason) will not work. (since this is off-topic, please contribute further at the link below if you'd like). Windows 2000 discussion aside, I'm hoping one day the AMD Radeon R4 98E4, Stoney Ridge graphics driver will work with Vista in addition to 7, 8, 8.1, and 10 along with several others like the Qualcomm Atheros QCA9377 among others (If you have Realtek audio, non-advanced mode (I2C/Serial I/O) Synaptics/Elantech and probably ALPS touchpads, and Realtek Ethernet, you are good as those still support Vista without any kernel mods provided by this or other mods. Rather than derail this thread, if you want to continue talk about AMD Graphics drivers, we can move the discussion to the other thread linked below, which does not have to pertain to just my model of AMD.

How difficult is it to add dxgkrnl functionality to win32k.sys and is it possible? in general how many type of functions should be added to win32k.sys ? Are @Ximonite aware of these missings ?

Jakob99 Posted October 10, 2022 Share Posted October 10, 2022 (edited) Looks like Firefox 105 doew not work. It installs, but opening it causes it to complain about WerUnregisterRuntimeExceptionModule not being located in KERNEL32.dll. This is on July 2022 update. I'm finally in! I had to scour around for a Firefox older than 105. I went with Firefox 101, which installs and opens as intended with no issues. Idk what version of Firefox was the first to introduce needing WerUnregisterRuntimeExceptionModule in Kernel32.dll, but I know Firefox 105 has it while Firerfox 101 does not. So for now, no Firefox 105 until @win32 can figure something out. Edited October 10, 2022 by Jakob99 1 Link to comment Share on other sites More sharing options...
win32 Posted October 11, 2022 Author Share Posted October 11, 2022 I added WerUnregisterRuntimeExceptionModule and got Firefox 106 running. So it should not be too long. 6 Link to comment Share on other sites More sharing options...

From what I Googled, this appears to be related to error dialogs or similar. 1 Link to comment Share on other sites More sharing options...
