DiskLED is Now Open Source

Helge Klein - Sun, 06/17/2018 - 22:48

DiskLED is a tool I wrote a while ago that displays performance counter data using an animated system tray icon. It comes with a graphical configuration dialog that lets you choose from all performance counters available on the local system – you can monitor network throughput just as easily as hard disk activity or memory usage.

There still seems to be a decent userbase – after all, DiskLED works on Windows 10 just as well as it did on XP. I sometimes get requests for new features or modifications. Unfortunately, I do not have the time for that. But I am more than happy to comply with Brian H’s request to make DiskLED open source.

You can find DiskLED’s source code on GitHub. Have fun!

Getting started with Bash on RISC OS

The Iconbar - Fri, 06/15/2018 - 07:53
There are lots of hidden treasures to try for free in PackMan (see our review from 2017). In this article we are going to go into more depth with Bash. Bash is a freely available on many systems (I use it all the time at work on Macs and Linux systems). It also provides the basis for running many other tools and automating things by writing short Bash scripts.

Once installed, you can start writing Bash directly in a single-tasking window by running the Bash App. But the best way to run it is from a terminal window. Just type the command Bash and you will be using bash.

Type in exit to return to the standard RISC OS command line.

Type in help to give you a list of commands at any time.

If you want to learn more about Bash, we recommend you start with the Wikipedia entry.

What is your favourite tool on !PackMan?

A new monitor for my RISC OS and Mac systems

The Iconbar - Fri, 06/08/2018 - 07:53
Recently I decided to upgrade my monitors. I have a MacBook Pro laptop and I have 2 monitors - one at work which runs my laptop (replacing a 27 inch 10 year old Apple work monitor) and one for home also hosts my RaspberryPi and Titanium. I wanted a high resolution (3840 x 2160 for work) monitor which would also play nicely with my other machines.

The latest Macs use Apple's USB-C connections. You can buy adapters for connecting in other types of connector such as HDMI or you can now buy monitors which have a USB-C connector. Apple offers an LG monitor which provides 5K and can also power the computer and handle the display on a single cable. If money is no object, you want an uncluttered desk and a 'to die for' screen quality on the latest Macs, the LG UltraFine 5K Display is the current top option.

Not only is this monitor very expensive but it will not work on my RISC OS kit as it only has a USB-C input.... One monitor which has also had a lot of very favourable press coverage is another LG model (27UD88-W). This is much more affordable (under 500 pounds), has USB-C input (not powerful enough to act as a power supply as well but fine to drive a 4K display), and also allows for HDMI and DP-IN as well. There are even a couple of old style USB ports for good measure. So how well does this model work for all the machines?

Very well is the short answer. The screen quality is great and you can have all the machines power up and then switch between them. The 27UD88-W has a single joystick type control under the screen and (IMHO) this is one of the nicest switches I have used on monitors - 2 clicks and I am on a different screen. The screen is ultra-sharp on both the Mac and the lower resolution Titanium 1920 x 1200 display.

One word of caution on moving up to a higher resolution screen. My combined switch box (which allows me to share screen and keyboard/mouse through one switch box) does not work on the higher resolution screens. So if you are using a switch box, you may want to verify what it can support.

A really nice feature of the higher resolution screen is that you have your other machines accessible via VNC. This also gives you some idea of the extra 'real estate' the monitors can give you if you are working on a Mac.

If you are looking for a godo quality monitor to provide a high resolution display, which also plays well with your RISC OS kit, the LG 27UD88-W should be one of your shortlist.

Drag'n'Drop Spring 2018 edition released

The Iconbar - Fri, 05/25/2018 - 07:53

The latest edition of Drag'n'Drop was released at The Wakefield show and is now available directly or via the Plingstore.

Drag'n'Drop is the long running online magazine, released as a PDF document which you can read on your computer or printout. As a PDF, the magazine can contain clickable links, taking you straight to downloads and websites. The news section is right up to date with the Wakefield Show.

The cover includes a picture of the classic Missile Command game, and there is a BASIC listing for the game. You can purchase all the code listing with the magazine to save typing. There is a nice explanation of how the code works.

There is a new series starting in this edition on using Schema2, complete with links to download the free version. Drag'n'Drop does many multi-edition series and back issues are available if you find yourself joining one mid-series.

The series on how RISC OS fonts work moves to part 2. We dissect Outline files and peek inside with a small BASIC program.

Paul Stewart (original founder of the magazine), makes a welcome return with a review of RaspberryRo Lite 3 from Fourth Dimension. He also has a second hardware review on the Vonets VP11G Wifi router. Great to have you back, Paul.

This months little utility to make the RISC OS experience even better is a WindowCloser utility. With one single application on your task bar you can list and close all open windows. A simple Icon Clipboard utility also allows you to copy and paste text between writable icons.

Finally, you can read reviews on the latest release of ArtWorks (is it worth the money for the new tool) and Philips Music Scribe (now available as a free download to Plingstore).

Something for everyone in this edition and an enjoyable and entertaining read with lots of practical projects.

The Magazine is available from the website and you can also buy a version with the code listings.

Inexpensive GPU Virtualization Options for Testing

Helge Klein - Fri, 05/25/2018 - 00:01
Contents

For a new chapter in my ongoing series of talks and articles about browser performance I wanted to examine how key user experience metrics like page load time are dependent on available hardware resources. I prepared a VM and started my tests with a single CPU core and 2 GB of RAM, planning to gradually add more cores, more RAM and, eventually, a GPU. As it turned out, the latter is harder than anticipated.

Virtualizing a GPU – the Options

There seem to be many different ways to equip a VM with a GPU these days, but not all of them make sense for a test environment. Nvidia Grid, specifically, is pretty expensive, given that it requires specific professional GPUs and supported server hardware, unlocked by Grid software licenses.

Another variant that I did not find suitable: GPU-enabled VMs, e.g. from AWS or Azure. The reason being not even cost (I would only have used the VM for a dozen hours or so), but flexibility (I had to be able to change the VM’s hardware configuration).

With Nvidia Grid and a cloud VM out of the way, I was left with the following options. Please note that I was looking for a simple and inexpensive solution.

  1. Client Hyper-V with RemoteFX
  2. Client Hyper-V with direct device assignment (DDA)
  3. VMware Workstation

Let’s take a look at each of these in turn.

Client Hyper-V with RemoteFX Configuration

RemoteFX GPU virtualization has been available in Windows 10 Client Hyper-V since version 1511. Some docs state that the Enterprise SKU of Windows 10 is required in the guest, but I did not find that to be correct: Pro and Enterprise gave identical results.

To enable RemoteFX GPU virtualization:

  • Host: in Hyper-V settings, enable a physical GPU for use with RemoteFX
  • Guest: in the VM’s settings, add a RemoteFX 3D Video Adapter to the VM

No need to care about GPU drivers in the VM: they are part of Hyper-V Integration Services.

Operation

With the above steps completed, you will see a virtual GPU in the VM (Microsoft RemoteFX Graphics Device – WDDM):

DXDiag seems to be quite happy with it:

Chrome not so much:

Also, there is no GPU in Task Manager:

Verdict

RemoteFX does not map (part of) the physical GPU into the VM. Instead, it virtualizes certain DirectX APIs. That may be enough for some uses cases, but Chrome is looking for something different and consequently sticks to software rendering.

By the way, a good indicator that there is no “real” GPU available in the VM is that you do not need to install GPU vendor drivers.

Client Hyper-V with Direct Device Assignment (DDA) DDA Requirements

DDA maps a physical GPU into a VM. While it is documented only for Windows Server I thought it just might work with Windows 10, too.

With DDA, the VM “sees” a real GPU. Therefore vendor drivers need to be installed in the VM.

DDA only works if the host machine’s BIOS supports SR-IOV. In other words, the BIOS must support relinquishing control of the PCI Express bus to the OS. That, unfortunately, is a capability typically only found in server hardware. SR-IOV is not to be confused with VT-d, which is typically found in consumer hardware but which is not to sufficient to make DDA work.

DDA and Licensing

Even if you have a machine that meets the hardware requirements for DDA outlined above, you may run into a problem of a very different nature: Nvidia’s consumer cards cannot be used because of restrictions in the driver. Nvidia’s Grid cards, on the other hand, require software licenses in addition to the professional-grade hardware. Rachel Berry has a good overview of Nvidia Grid licensing.

AMD GPUs (purportedly) do support DDA, but I did not test that.

VMware Workstation Configuration

The first thing you may notice after installing VMware Workstation is that it does not work if Hyper-V is enabled. If you want to keep using Hyper-V your best option is to create a new boot menu entry with Hyper-V disabled. That way you can switch between Hyper-V and VMware Workstation simply by rebooting. From Stack Overflow:

C:\>bcdedit /copy {current} /d "No Hyper-V" The entry was successfully copied to {ff-23-113-824e-5c5144ea}. C:\>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off The operation completed successfully.

As with RemoteFX, there is no need to care about GPU drivers in the VM: they are part of VMware Tools. This indicates that the concept is similar in nature to RemoteFX.

Operation

The virtual GPU you will see in the VM is of the type VMware SVGA 3D:

Again, DXDiag is happy:

Again, Chrome not so much:

As with RemoteFX, there is no GPU in Task Manager:

Verdict

From an application’s point of view, VMware Workstation GPU virtualization is similar to RemoteFX: potentially good enough for some use cases, but there is no “real” GPU in the VM.

Conclusion

It’s 2018. This should be easier!

GPU virtualization is most definitely not mainstream yet. Currently, server hardware with either AMD or Nvidia Grid GPUs is required. That makes testing unnecessarily difficult and expensive.
