similar to: [PATCH v3] xen/console: buffer and show origin of guest PV writes

Guests other than domain 0 using the console output have previously been controlled by the VERBOSE define, but with no designation of which guest''s output was on the console. This patch converts the HVM output buffering to be used by all domains, line buffering their output and prefixing it with the domain ID. This is especially useful for debugging stub domains.

The sound file is played correctly for the first time, then when rewind to the initial position. then copy PCM to buffer, the OpenAL report an error. It seems like the OpenAL doesn't recognize the PCM data. The OpenAL error number : AL_INVALID_VALUE 0xA003 void Buffer::PCMData (ALuint id, ALenum eFormat, ALvoid *data, ALsizei size, ALsizei freq) { // Copy

Hi. We''re testing the most recent ZFS version from OpenSolaris ported to FreeBSD. Kris (CCed) observed strange situation. In function arc_read() he had a panic on assertion that we try to unlock a lock which is not beeing held: rw_enter(&pbuf->b_hdr->b_datalock, RW_READER); err = arc_read_nolock(pio, spa, bp, done, private, priority, flags, arc_flags, zb);

Those two should always be delivered first imo.

There is a race condition between XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY and HVMOP_track_dirty_vram hypercall. Although HVMOP_track_dirty_vram is called many times from qemu-dm which is connected via VNC, XEN_DOMCTL_SHADOW_OP_ENABLE_LOGDIRTY is called only once from a migration process (e.g. xc_save, libxl-save-helper). So the race seldom happens, but the following cases are possible.

Otherwise we may leak memory when setting up nHVM fails half way. This implies that the individual destroy functions will have to remain capable (in the VMX case they first need to be made so, following 26486:7648ef657fe7 and 26489:83a3fa9c8434) of being called for a vCPU that the corresponding init function was never run on. Once at it, also remove a redundant check from the corresponding

The iommu is enabled by default when xen is booting and later disabled in iommu_setup() when no iommu is present. But under some circumstances iommu-code can be called before iommu_setup() is processed. If there is no iommu available xen crashes. This can happen for example when panic(...) is called that got introduced with patch "x86-64: detect processors subject to AMD erratum #121 and

Xen is crashing for me since version 4.1.3 during boot on a AMD machine. This happens since patch "x86-64: detect processors subject to AMD erratum #121 and refuse to boot." Instead of the actual panic-message from the patch the following stacktrace appears (i typed it down from screen, so it might contain typos) find_iommu_for_device amd_iommu_ioapic_update_ire timer_interrupt

Host S3 implicitly resets the host TSC to 0, but the tsc offset for hvm domains is not recalculated when they resume, causing it to go into negative values. In Linux guest using tsc clocksource, this results in a hang after wrap back to positive values since the tsc clocksource implementation expects it reset.

The previous order of relinquish resource is: relinquish_domain_resources() -> vcpu_destroy() -> nvmx_vcpu_destroy(). However some L1 resources like nv_vvmcx and io_bitmaps are free in nvmx_vcpu_destroy(), therefore the relinquish_domain_resources() will not reduce the refcnt of the domain to 0, therefore the latter vcpu release functions will not be called. To fix this issue, we need to

Use the new non-coherent DMA API including proper ownership transfers. This also means we can allocate the memory as DMA_TO_DEVICE instead of bidirectional.

I have non terminate loop when decode speex bits stream. These are my pseudocode for encoding and decoding -- Encode -- while(stillhaveinput) { speex_encode(enc_state, curr_spx_frame, &bits); } speex_bits_insert_terminator(&bits); speex_bits_write(&bits,(char *)(pBufferOut),MAX_LEN); -- Decode (these code loop forever) -- speex_bits_read_from(&bits, (char *) pBuf,act_length);

If I configure openssh-2.1.1p4 with the --with-skey option on a Redhat Linux 6.2 system which has openssl-0.9.5a and skey (the logdaemon 6.2 version) installed, the compile fails with the following errors: auth1.c: In function `do_authloop': auth1.c:331: warning: implicit declaration of function `skey_keyinfo' auth1.c:331: warning: initialization makes pointer from integer without a cast

Hi all, Just looking over fole_s_connect() in win32ole.c and I noticed this bit: hr = CLSIDFromProgID(pBuf, &clsid); ... hr = GetActiveObject(&clsid, 0, &pUnknown); ... hr = pUnknown->lpVtbl->QueryInterface( pUnknown, &IID_IDispatch, (void **)&pDispatch ); Using win32-api, that would be something like: IID_IUnknown =

Add the new MEM_EVENT_REASON_MSR event type. Works similarly to the other register events, except event.gla always contains the MSR address (in addition to event.gfn, which holds the value). MEM_EVENT_REASON_MSR does not honour the HVMPME_onchangeonly bit, as doing so would complicate the hvm_msr_write_intercept() switch-based handling of writes for different MSR addresses, with little added

The UDP binding logic will reuse local port numbers immediately. This causes problems for TFTP, which assumes a very low probability of a source port number being reused. The consequence is that lpxelinux.0 may end up downloading an incorrect file (e.g. attempting to download pxelinux.cfg/default but actually receiving a copy of ldlinux.c32, due to the port number having been reused).
