2022-11-17PCI/MSI: Validate MSI-X contiguous restriction earlyThomas Gleixner1-2/+9
With interrupt domains the sanity check for MSI-X vector validation can be done _before_ any allocation happens. The sanity check only applies to the allocation functions which have an 'entries' array argument. The entries array is filled by the caller with the requested MSI-X indices. Some drivers have gaps in the index space which is not supported on all architectures. The PCI/MSI irq domain has a 'feature' bit to enforce this validation late during the allocation phase. Just do it right away before doing any other work along with the other sanity checks on that array.

2022-11-17PCI/MSI: Reject multi-MSI earlyThomas Gleixner3-0/+35
When hierarchical MSI interrupt domains are enabled then there is no point to do tons of work and detect the missing support for multi-MSI late in the allocation path. Just query the domain feature flags right away. The query function is going to be used for other purposes later and has a mode argument which influences the result: ALLOW_LEGACY returns true when: - there is no irq domain attached (legacy support) - there is a irq domain attached which has the feature flag set DENY_LEGACY returns only true when: - there is a irq domain attached which has the feature flag set This allows to use the function universally without ifdeffery in the calling code.

msi.c is a maze of randomly sorted functions which makes the code unreadable.

2022-11-17clocksource/drivers/hyper-v: Include asm/hyperv-tlfs.h not asm/mshyperv.hThomas Gleixner4-3/+13
clocksource/hyperv_timer.h is included into the VDSO build. It includes asm/mshyperv.h which in turn includes the world and some more. This worked so far by chance, but any subtle change in the include chain results in a build breakage because VDSO builds are building user space libraries. Include asm/hyperv-tlfs.h instead which contains everything what the VDSO build needs except the hv_get_raw_timer() define. Move this define into a separate header file, which contains the prerequisites (msr.h) and is included by clocksource/hyperv_timer.h. Fixup drivers/hv/vmbus_drv.c which relies on the indirect include of asm/mshyperv.h. With that the VDSO build only pulls in the minimum requirements.
