OPINION/SPECULATION: After more tests, I am still encountering the odd behaviour of VMware (14.1.2 with vmmon patch) and Kernel 4.18-rc1, but did notice one possible clue.. Looking at the # systemctl status vmware.service output, it includes the following: Jun 18 01:02:03 rgtest vmware[5663]: Blocking file system[FAILED] I think this should not be there, as VMBlock has been … Continue reading →
VMware 14.1.2 worked OK with Kernel 4.17, on my Fedora 28 test system, but after updating to 4.18-rc1 the following occurred: Modules (vmmon/vmnet) compiled OK, but – after further testing – appeared to have a runtime problem.. I applied the vmmon patches from Michal Kubeček, at https://github.com/mkubecek/vmware-host-modules/commit/3f2a6c720f68 and this also compiled cleanly. When I ran # vmware-modconfig … Continue reading →
Kernel 4.18-rc1 has been released – earlier than expected, but Linus is in Japan, where it was already Sunday.. Brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/1806.2/00125.html Tested with VMware 14.1.2, and vmmon/vmnet compile OK, but NVIDIA fails: ………………………….

Kernel 4.17 is out, and details of changes from -rc7 are here: http://lkml.iu.edu/hypermail/linux/kernel/1806.0/01332.html No real surprises, so far, and it is OK with VMware 14.1.2, and NVIDIA 396.24. Apparently the major version bump to Linux 5.0 might occur at around the Kernel 4.20 mark…. Robert Gadsdon June 3, 2018.

There are now patches available to deal with the host of ‘objtool‘ warnings when compiling the kernel with GCC8: …………………………….. drivers/video/fbdev/core/fbmem.o: warning: objtool: fb_set_var()+0x209: sibling call from callable instruction with modified stack frame drivers/video/fbdev/core/fbmem.o: warning: objtool: do_remove_conflicting_framebuffers()+0xa6: sibling call from callable instruction with modified stack frame drivers/video/fbdev/core/fbmem.o: warning: objtool: register_framebuffer()+0x14b: sibling call from callable instruction with modified … Continue reading →
Fedora 28 has GCC 8.1.1 available (currently in ‘updates-testing‘ repo), and I tested this with Kernel 4.17-rc4, to see if there was any improvement in the horde of warnings generated with 8.0.1.

Tried Kernel 4.16.7 on Fedora 28 (GCC 8.0.1), and this now compiles successfully, although still with a lot of ‘warnings’..
