Some devices (e.g. ixg in MSI-X mode) don't to have their handlers called when no interrupt are pending. So add an extra ih_pending field to struct intrhand, which is incremeted when the handler is not called because of IPL level and reset to 0 when called. Check this in Xen's resume assembly to call only handlers that are really pending.

If possible, register a per-cpu callback via HVMOP_set_evtchn_upcall_vector. From FreeBSD. This requires acking the interrupt in hypervisor_pvhvm_callback. Don't try to use x86_cpu_idle_xen() for PVHVM, it cause the domU to hang. FreeBSD doesn't seem to use it either.

We can get there with some software interrupts pending in autoconf XXX needs to be looked at.

Fix a problem with intr_unmask() that can cause a forever-loop: - When handling the source-is-masked case in the interrupt vector, set the interrupt bit in a new ci_imasked field and ensure the bit is cleared from ci_ipending. - In intr_unmask(), transfer the bit from ci_imasked to ci_ipending for non-level-sensitive interrupts (the PIC does the work for us in the level-sensitive case), and only force pending interrupts to be processed in this case. (In all cases, make sure the now-unmasked bit is cleared from ci_imasked.) Before, the bit was left in ci_ipending so as not to use edge-triggered interrupts while the source is masked, but Xspllower() relies on the pending bits getting cleared. Tested by forcing all wm(4) interrupts on my test system though an intr_mask() / softint / intr_unmask() cycle and exercising the network heavily.

Excise XEN specific code out of x86/x86/intr.c into xen/x86/xen_intr.c While at it, separate the source function tracking so that the interrupt paths are truly independant. Use weak symbol exporting to provision for future PVHVM co-existence of both files, but with independant paths. Introduce assembler code such that in a unified scenario, native interrupts get first priority in spllower(), followed by XEN event callbacks. IPL management and semantics are unchanged - native handlers and xen callbacks are expected to maintain their ipl related semantics. In summary, after this commit, native and XEN now have completely unrelated interrupt handling mechanisms, including intr_establish_xname() and assembler stubs and intr handler management. Happy Christmas!

Drop NENTRY() from the x86 kernels, use ENTRY(). With PMCs (and other hardware tracing facilities) we have a much better ways of monitoring the CPU activity than GPROF, without software modification. Also I think GPROF has never worked, because the 'start' functions of both i386 and amd64 use ENTRY(), and it would have caused a function call while the kernel was not yet relocated.

Unmap the kernel from userland in SVS, and leave only the needed trampolines. As explained below, SVS should now completely mitigate Meltdown on GENERIC kernels, even though it needs some more tweaking for GENERIC_KASLR. Until now the kernel entry points looked like: FUNC(intr) pushq $ERR pushq $TRAPNO INTRENTRY ... handle interrupt ... INTRFASTEXIT END(intr) With this change they are split and become: FUNC(handle) ... handle interrupt ... INTRFASTEXIT END(handle) TEXT_USER_BEGIN FUNC(intr) pushq $ERR pushq $TRAPNO INTRENTRY jmp handle END(intr) TEXT_USER_END A new section is introduced, .text.user, that contains minimal kernel entry/exit points. In order to choose what to put in this section, two macros are introduced, TEXT_USER_BEGIN and TEXT_USER_END. The section is mapped in userland with normal 4K pages. In GENERIC, the section is 4K-page-aligned and embedded in .text, which is mapped with large pages. That is to say, when an interrupt comes in, the CPU has the user page tables loaded and executes the 'intr' functions on 4K pages; after calling SVS_ENTER (in INTRENTRY) these 4K pages become 2MB large pages, and remain so when executing in kernel mode. In GENERIC_KASLR, the section is 4K-page-aligned and independent from the other kernel texts. The prekern just picks it up and maps it at a random address. In GENERIC, SVS should now completely mitigate Meltdown: what we put in .text.user is not secret. In GENERIC_KASLR, SVS would have to be improved a bit more: the 'jmp handle' instruction is actually secret, since it leaks the address of the section we are jumping into. By exploiting Meltdown on Intel, this theoretically allows a local user to reconstruct the address of the first text section. But given that our KASLR produces several texts, and that each section is not correlated with the others, the level of protection KASLR provides is still good.

Always use END() markers when declaring functions in assembly, so that ld can compute the size of the functions. A few remain. While here, fix a bug in the INTRSTUB macro: we are falling through resume_, but it is aligned, so it looks like we're executing the inter- function padding - which probably happens to contain NOPs, but that's still bad.

Move the virtual address of the LAPIC page out of the data segment on amd64 and i386. The old design was error-prone, and it didn't allow us to map the data segment with large pages. Now, the VA is allocated dynamically in the pmap bootstrap code, and entered manually later. We go from using &local_apic to using *local_apic_va, and we therefore need one more level of indirection in the asm code. Discussed on tech-kern.

Pull up following revision(s) (requested by spz in ticket #1772): sys/arch/amd64/amd64/trap.c: revision 1.71 via patch sys/arch/amd64/amd64/vector.S: revision 1.41 via patch sys/arch/amd64/include/frameasm.h: patch Treat traps in kernel mode during the 'return to user' iret sequence as user faults. Based heavily in the i386 code with the correct opcode bytes inserted. iret path tested, arranging for segment register errors is harder. User %fs and %gs (32bit apps) are loaded much earlier and any errors will generate kernel panics - there is probably code to try to stop the invalid values being set. If we get a fault setting the user %gs, or on a iret that is returning to userspace, we must do a 'swapgs' to reload the kernel %gs_base. Also save the %ds, %es, %fs, %gs selector values in the frame so they can be restored if we finally return to user (probably after an application SIGSEGV handler has fixed the error). Without this any such fault leaves the kernel running with the wrong %gs offset and it will most likely fault again early in trap(). Repeats until the stack tramples on something important. iret change works, invalid %gs is a little harder to arrange.

Pull up following revision(s) (requested by spz in ticket #1772): sys/arch/amd64/amd64/trap.c: revision 1.71 via patch sys/arch/amd64/amd64/vector.S: revision 1.41 via patch sys/arch/amd64/include/frameasm.h: patch Treat traps in kernel mode during the 'return to user' iret sequence as user faults. Based heavily in the i386 code with the correct opcode bytes inserted. iret path tested, arranging for segment register errors is harder. User %fs and %gs (32bit apps) are loaded much earlier and any errors will generate kernel panics - there is probably code to try to stop the invalid values being set. If we get a fault setting the user %gs, or on a iret that is returning to userspace, we must do a 'swapgs' to reload the kernel %gs_base. Also save the %ds, %es, %fs, %gs selector values in the frame so they can be restored if we finally return to user (probably after an application SIGSEGV handler has fixed the error). Without this any such fault leaves the kernel running with the wrong %gs offset and it will most likely fault again early in trap(). Repeats until the stack tramples on something important. iret change works, invalid %gs is a little harder to arrange.

Move all the XEN differences to a single conditional. Merge the XEN/non-XEN versions of INTRFASTEXIT and INTR_RECURSE_HWFRAME by using extra defines. Split INTRENTRY so that code can insert extra instructions inside user/kernel conditional. Add a ';' that got deleted in a slight tidyup. Rejig the way TRAP() and ZTRAP() are defined and add Z/TRAP_NJ() that excludes the 'jmp alltraps'. Use the _NJ versions for trap entries with non-standard code. Move all the KDTRACE_HOOKS code into a single block inside the IDTVEC(trap03) code. This removes a mis-predicted from every trap when KDTRACE_HOOKS are enabled. Add a few blank lines, need some comments as well :-) No functional changes intended. Let the user of INTRENTRY_L() place a label on the 'swapgs' used when faulting from user space. If we get a fault setting the user %gs, or on a iret that is returning to userspace, we must do a 'swapgs' to reload the kernel %gs_base.

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

- Fix tlbflushg() to behave like tlbflush(), if page global extension (PGE) is not (yet) enabled. This fixes the issue of stale TLB entry, experienced early on boot, when PGE is not yet set on primary CPU. - Rewrite i386/amd64 TLB interrupt handlers in C (only stubs are in assembly), which simplifies and unifies (under x86) code, plus fixes few bugs. - cpu_attach: remove assignment to cpus_running, as primary CPU might not be attached first, which causes reset (and thus missed secondary CPUs).

Ephemeral mapping (emap) implementation. Concept is based on the idea that activity of other threads will perform the TLB flush for the processes using emap as a side effect. To track that, global and per-CPU generation numbers are used. This idea was suggested by Andrew Doran; various improvements to it by me. Notes: - For now, zero-copy on pipe is not yet enabled. - TCP socket code would likely need more work. - Additional UVM loaning improvements are needed. Proposed on <tech-kern>, silence there. Quickly reviewed by <ad>.

amd64 (aka x86-64) support for Xen. Based on the OpenBSD port done by Mathieu Ropert in 2006. DomU-only for now. An INSTALL_XEN3_DOMU kernel with a ramdisk will boot to sysinst if you're lucky. Often it panics because a runable LWP has a NULL stack (really, it's all of l->l_addr which is has been zeroed out while the process was on the queue !) TODO: - bug fixes :) - Most of the xpq_* functions should be shared with xen/i386 - The xen/i386 assembly bootstrap code should be remplaced with the C version in xenamd64/amd64/xpmap.c - see if a config(5) trick could allow to merge xenamd64 back to xen or amd64.

Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

In the TLB shootdown handlers, don't ack the request until the invalidation is complete. We could end up loading bogus translations due to a speculative load if the calling CPU recycles a PDE/PTE, and these may not be shot down before the handler returns. Pointed out by yamt. I think this is very unlikely to happen but it's better to be on the safe side. To be revisted later, as the invalidations are time consuming and it would be nice to release the caller sooner rather than later.

Pass pointers to frames from assembly, do not use the 'frame on stack as argument passed by value' trick, as gcc 3.3.x makes (valid) assumptions about the stack that will not be true. Costs 2 instructions per trap/syscall on i386, 4 per interrupt for MP. One instruction per trap/syscall on amd64, 2 per interrupt for MP. I expect gcc 3.3.1 to make up for this by better optimization (it'd better..) While here, make amd64 compile again by using subr_mbr_disk.c
