Hi folks, Kvm.git: commit 2ee44a580db58f98d85b57bfc468bbc5729ec9b3 Author: Avi Kivity Date: Mon Mar 21 12:53:58 2011 +0200 My build system: RHEL5u5, Linux kvm-build 2.6.38-rc4+ #1 SMP Sat Feb 19 15:35:09 CST 2011 x86_64 x86_64 x86_64 GNU/Linux When I make kvm, I get the following error. drivers/usb/serial/usb_wwan.c: In function 'play_delayed': drivers/usb/serial/usb_wwan.c:702: error: 'struct dev_pm_info' has no member named 'usage_count' And I look at the 702Row of usb_wwan.c It shows: atomic_dec(&port->serial->interface->dev.power.usage_count); I see usage_count is declared in kvm.git/include/linux/pm.h , but it is declared between "#ifdef" and "#endif". #ifdef CONFIG_PM_RUNTIME . Kernel of build system doesn't define CONFIG_PM_RUNTIME, so I got the kvm make error. Anybody knows the solution ? Thanks.
