nvram | change NVRAM contents from the command line

Firstly, I find it strange to see ORG 0xFF000 together with USE16. It think in real address mode, ORG is meant to be a 16-bit offset in a 64KB segment.

Because on the first pass, the assembler does not yet know about the end and init_16 labels, it could just skip the times that depends on it. This would leave the current offset ($) at ORG. Then come the 3 bytes from encoding cli and the short jump jmp init_16, followed by the 13 bytes produced by align 16.
At this point, both labels are known and a following pass can start using these offsets. code_size is calculated to be 16 (the difference between both labels) and so times fills with 4080 nops (4096-16).
Although the 2 labels have now moved up in memory by 4080 bytes, their difference is still the same (16) and so no further passes are needed. The code is resolved.

Furthermore, I can't figure why the cli instruction always ends up in the 0xFFFF0 addres independently if add instructions between the cli and jump. It is the objective, but I don't know how it works

Adding a few instructions right after this cli does not change the procedure that was outlined for as long as the difference between both labels stays 16. You could insert instructions worth 13 bytes.

Upstream Linux v5.2-rc1 introduced the kernel parameter page_alloc.shuffle, which is a Boolean flag that is automatically enabled if both of the following conditions are true:

• It's not manually disabled by adding page_alloc.shuffle=0 to the kernel parameter list.
• The kernel is running on a system with firmware that supports ACPI 6.2 and the firmware has communicated to the kernel through the Heterogeneous Memory Attribute Table (HMAT) that the system has a memory-side cache in at least one of the memory domains.

When this parameter is enabled, the kernel page allocator randomizes its free lists in the hope of reducing conflicts on the memory-side cache.

Examples of systems on which it's automatically enabled include KNL/KNM with MCDRAM that is partially or fully configured to run in Cache Mode and CSX/CPX with persistent memory that is partially or fully configured to run in Memory Mode. On all of these systems, there is a direct-mapped memory-side cache, although many implementation details are different.

Free list shuffling provides sustainable good performance, but not necessarily optimal or close to optimal. This is in contrast to running at high performance at first due to good memory-side cache utilization, but then the performance degrades over time due to increasing cache conflicts.

That said, I don't think anyone has tested the impact of free list shuffling on performance on a system with persistent memory running in Memory Mode, even though it's automatically enabled.

There are currently no other potential optimizations for Memory Mode accepted in the kernel.

IP Address of the first interface can get through the hw_eth0 property of the vmware_guest_info module result.
Here's the sample playbook.

Ok, shortly after posting we figured it out. Seems like a mount point has changed (I expect due to a linux kernel update) and we have not used the nofail option in /etc/fstab as described in the aws knowledge center, this caused the server to hang at boot.

Going forward we will also ensure we use UUID mounting so we are independent on the device naming in /dev/.

This is more of a comment, really...

I don't use libvirt myself, but as far as I can tell there aren't any audio devices in your config.

Here are the qemu command line options I use for guest (Win10 and others) audio output to PulseAudio output on -machine q35 :

I had similar issue and it worked:

Reset Your Mac’s SMC

On iMac, Mac mini, Mac Pro, and Xserve

Choose Apple menu > Shut Down After your Mac shuts down, unplug the power cord Wait 15 seconds Plug the power cord back in Wait 5 seconds, then press the power button again to turn on your Mac

On a Mac that has the Apple T2 chip

Choose Apple menu > Shut Down After your Mac shuts down, press and hold its power button for 10 seconds Release the power button, then wait a few seconds Press the power button again to turn on your Mac

If that doesn’t work, try the following for MacBooks:

Choose Apple menu > Shut Down After your Mac shuts down, press and hold the right Shift key, the left Option key, and the left Control key for 7 seconds Keep holding those keys while you press and hold the power button for another 7 seconds Release all three keys and the power button, then wait a few seconds Press the power button again to turn on your Mac

If that doesn’t work, try the following for Mac Desktops

Choose Apple menu > Shut Down After your Mac shuts down, unplug the power cord Wait 15 seconds Plug the power cord back in Wait 5 seconds, then press the power button again to turn on your Mac

Spotlight re-index Spotlight Search Not Working on MacBook, How-To Fix

It appears that at least some instances of this issue can be attributed to problematic Spotlight indexing Re-index your startup drive and any external USB drives by following these instructions: Open System Preferences (in the Apple menu; an upper-left portion of the screen) Open the Spotlight pane, then select the Privacy tab. Drag your hard drive(s) and any USB drives, USB memory sticks, etc. from the desktop to the Privacy list Remove the items from your privacy list If the above process doesn’t work to resolve your mouse/keyboard freezing issue, try downloading Hidden Files to view invisible files on your mounted drives.

Delete the file.Spotlight-V100 from your startup drive and any connected USB drive then restart.

Disable multi-touch gestures Some users have reported that disabling multitouch gestures in System Preferences resolves this issue. Other users report that simply disabling then re-enabling gestures resolves the problem. mac trackpad accessibility settings

There are two places where you make adjustments to your Trackpad, in System Preferences > Trackpad and System Preferences > Accessibility > Mouse & Trackpad. mac trackpad settings

It's from this site:https://appletoolbox.com/mac-os-x-10-6-3-mousekeyboard-freezes-continue-more-fixes/

You can use a combination of the filter map to extract the stdout_lines of all the elements of your list and then flatten the resulting list of list in order to do this.

Given the playbook:

You can run any live linux OS, chroot to your still existing installed Linux Distribution, and reinstall grub, which will re-add Linux to the boot menu alongside Windows.
