| 2017-05-27 | add missing prototype | Mike Larkin | |
| 2017-05-26 | Enable chvgpio(4) in RAMDISK_CD on amd64. | Stefan Sperling | |
| Makes the King Jim portabook's keyboard work in bsd.rd. ok deraadt mlarkin | |||
| 2017-05-25 | Replace the only usage of x86_pause() with SPINLOCK_SPIN_HOOK. | Visa Hankala | |
| OK dlg@ | |||
| 2017-05-25 | Drop trailing semicolon from a macro. | Visa Hankala | |
| OK dlg@ | |||
| 2017-05-19 | Respect max VPID/ASID limits. VMX VPIDs are capped at 4095, for now. | Mike Larkin | |
| 2017-05-19 | return EIO to vmd if the guest HLTs with interrupts disabled | Mike Larkin | |
| 2017-05-18 | Since copyin(9) already doeas access 32-bit quantities atomically, we can | Mark Kettenis | |
| add copyin32(9) as a simple C wrapper around it. These wrappers do check alignment and return EFAULT if the userland pointer is misaligned. This is enough to guarantee that the access doesn't cross a cache line boundary which could make the access non-atomic. ok mpi@, visa@, tedu@ | |||
| 2017-05-16 | Tweak previous, s/int/unsigned/, since the format character is %u. | YASUOKA Masahiko | |
| 2017-05-16 | Compare device pathes properly to find the booted disk. | YASUOKA Masahiko | |
| Work with and test by Michele Curti. | |||
| 2017-05-12 | Make copyin(9) and copyout(9) atomic for naturally aligned 32-bit words. | Mark Kettenis | |
| ok mpi@, visa@ | |||
| 2017-05-12 | Make atomic.h ready to be included in userland. | Martin Pieuchot | |
| - prefix the LOCK macro with an underscore - keep setbits/clearbits and virtio barriers inside _KERNEL ok dlg@, kettenis@ | |||
| 2017-05-11 | panic doesn't need \n. | Mike Larkin | |
| Suggested by Michael W. Bombardieri, thanks. | |||
| 2017-05-11 | Casting int is required for passing uint64 value to "%u" since we don't | YASUOKA Masahiko | |
| assume the size of int. The problem was spotted by Michele Curti. | |||
| 2017-05-10 | The setting of the cpu feature flags for PCLMUL and AES-NI was guarded with | Theo Buehler | |
| !SMALL_KERNEL and CRYPTO. Move it out of !SMALL_KERNEL to make use of these features on RAMDISK_CD. Fixes a performance regression in the installer introduced with the new aes implementation. In particular, it halves the time needed to extract baseXX.tgz and compXX.tgz on my T420. tweaks & ok mikeb | |||
| 2017-05-08 | After a break point at the beginning of a function, printing its | Alexander Bluhm | |
| arguments faulted in ddb. Accessing the register arguments was off by one and in wrong order. OK dlg@ | |||
| 2017-05-08 | add a BUS_DMA_64BIT flag to bus_dma on all our archs. | David Gwynne | |
| this is so drivers can advertise that they can handle 64 dma addresses to the platform. it may choose to handle dmamaps differently based on this flag. tweaks and ok tom@ ok kettenis@ | |||
| 2017-05-08 | add printing of arguments in stack traces. | David Gwynne | |
| this relies on building the kernel with -msave-args, which has functions save their register arguments on the stack, so ddb can easily find them and print them. while here try to print arguments out of registers if we're at the top of the stack (ie, if we set a breakpoint on a function entry). -msave-args is only added to the compiler flags if the kernel has been configured with ddb. this means it wont waste the space on RAMDISK kernels because they don't include ddb. inspired by similar functionality that has been in use on solaris and its derivatives for well over a decade. ok deraadt@ | |||
| 2017-05-07 | further improvement to vmm fpu handling (support avx and avx2, block | Mike Larkin | |
| avx512 and various xsave* instructions) tested by many | |||
| 2017-05-05 | Allow setting guest %xcr0 from vmd(8). | Mike Larkin | |
| Tested on linux and amd64 OpenBSD guests. Posted to tech by Pratik Vyas. | |||
| 2017-05-02 | Switch glxsb(4), VIA padlock and AES-NI drivers over to the new AES | Mike Belopuhov | |
| 2017-05-02 | Allow setting of guest MSRs from vmd(8). This change is the first part of | Mike Larkin | |
| a larger effort to implement vmctl send/vmctl receive (snapshot and VM migration). From Pratik Vyas, Siri Chandana, Harshada Mone and Ashwin Agrawal, a group of students I am supervising. ok kettenis | |||
| 2017-04-30 | Remove some KGDB leftovers. | Martin Pieuchot | |
| From Amit Kulkarni. | |||
| 2017-04-30 | Rename Debugger() into db_enter(). | Martin Pieuchot | |
| Using a name with the 'db_' prefix makes it invisible from the dynamic profiler. ok deraadt@, kettenis@, visa@ | |||
| 2017-04-30 | Unifdef KGDB. | Martin Pieuchot | |
| It doesn't compile und hasn't been working during the last decade. ok kettenis@, deraadt@ | |||
| 2017-04-28 | add some comments. no functional change | Mike Larkin | |
| 2017-04-28 | vmm: don't use invvpid if we didn't detect vpid capability during | Mike Larkin | |
| vcpu setup | |||
| 2017-04-27 | rename a struct that was denoted as "VMX only" to make it more clear | Mike Larkin | |
| that it can be used in SVM and VMX. no functional change | |||
| 2017-04-27 | use a more descriptive value from the VEI_DIR_xxx enum instead of a | Mike Larkin | |
| hardcoded number. no functional change | |||
| 2017-04-27 | vmm(4): proper save/restore of FPU context during entry/exit. | Mike Larkin | |
| tested by reyk, dcoppa, and a few others. ok kettenis@ on the fpu bits ok deraadt@ on the vmm bits | |||
| 2017-04-26 | Convert some hardcoded function names in printfs into %s / __func__. | Mike Larkin | |
| Some of these pointed out by Michael W. Bombardieri, I went through the file and fixed the rest. No functional change. | |||
| 2017-04-26 | Fix a typo relating to savefpu alignment | Mike Larkin | |
| ok kettenis | |||
| 2017-04-20 | Tweak lock inits to make the system runnable with witness(4) | Visa Hankala | |
| on amd64 and i386. | |||
| 2017-04-20 | Hook up mutex(9) to witness(4). | Visa Hankala | |
| 2017-04-20 | Hook up mplock to witness(4) on amd64 and i386. | Visa Hankala | |
| 2017-04-20 | Add routines for saving stack traces and printing saved traces | Visa Hankala | |
| on amd64 and i386. With guenther@ | |||
| 2017-04-16 | Replace fetch_and_add() with atomic_inc_int_nv() from <sys/atomic.h> | Visa Hankala | |
| to make the code more similar to sparc64's. OK mpi@, guenther@, kettenis@ | |||
| 2017-04-14 | SVM: calculate max ASID value and save for later use. This will be used in | Mike Larkin | |
| an upcoming diff to handle ASID/VPID reuse/rollover. | |||
| 2017-04-13 | Provide mips64 with kernel-facing TCB_{GET,SET} macros that store it | Philip Guenther | |
| in struct mdproc. With that, all archs have those and the __HAVE_MD_TCB macro can be unifdef'ed as always defined. ok kettenis@ visa@ jsing@ | |||
| 2017-04-02 | Filter out RDTSCP, needed to handle solaris guests. We set the VMX control | Mike Larkin | |
| to enable RDTSCP to 0, so when solaris attempted to use the instruction (since it wasn't filtered out of CPUID information), the CPU issued an #UD exception. | |||
| 2017-03-28 | Properly handle VMX entry controls governing guest processor mode. | Mike Larkin | |
| Before seabios, this didn't matter much but now it does since various bootloaders/kernels need such treatment. ok deraadt | |||
| 2017-03-28 | add RDTSCP flags to identcpu.c | Mike Larkin | |
| ok guenther, deraadt | |||
| 2017-03-27 | typo in debug build | Mike Larkin | |
| 2017-03-27 | add a newline to an error printf | Mike Larkin | |
| 2017-03-27 | hibernate_free() should not be called from MD code, acpi_sleep_state() | Theo de Raadt | |
| unwinds that. Upon hibernate fail, this was a collection of double-frees.. ok claudio mlarkin | |||
| 2017-03-26 | KNF | Jeremie Courreges-Anglas | |
| 2017-03-26 | discard MSR reads from unknown MSRs instead of passing them through. That | Mike Larkin | |
| behaviour was needed during early development but not anymore. Suppress the printf that accompanied these exits since linux guests go probing wildly into msr-land on each boot. ok deraadt | |||
| 2017-03-26 | Add "AVX" to the comment above the previous commit. Spotted by reyk | Mike Larkin | |
| 2017-03-26 | Suppress AVX from the extended CPUID flags. Our AVX treatment is currently | Mike Larkin | |
| incomplete and enabling it leads ubuntu guests to try and use the feature, with incorrect results. We can re-enable this at a later date when AVX is properly handled. | |||
| 2017-03-25 | Split vmm_probe() into a vmm_enabled() function, to better follow the | Theo de Raadt | |
| probe/attach approach used by mainbus. ok mlarkin kettenis | |||
| 2017-03-25 | Use explicit operand with SVM instructions as clang doesn't recognize the | Mark Kettenis | |
| implicit form. ok mlarkin@ | |||
