What are the sizes of GDTR, LDTR, IDTR and TR registers?

Asked 2021-Jun-10 at 12:33

I've searched up on a lot on the net and every time I can only find the sizes of GDT, LDT and IDT.

Here I'm not asking for the size of the table, but I'm asking about the sizes of the registers

I know that GDTR is a 64 bit register, but clueless about the others.

IDTR and GDTR appear to be 10 bytes each.

IDTR can also point anywhere in virtual address space, so obviously its base has to be 64-bit as well. lidt and lgdt take the same limit / base structure format, and the pseudocode shows that in 64-bit mode they do:

QUESTION

Why am I not receiving interrupts on Port Status Change Event with the Intel's xHC on QEMU?

Asked 2021-Apr-26 at 06:13

I'm coding a small OS kernel which is supposed to have a driver for the Intel's xHC (extensible host controller). I got to a point where I can actually generate Port Status Change Events by resetting the root hub ports. I'm using QEMU for virtualization.

I ask QEMU to emulate a USB mouse and a USB keyboard which it seems to do because I actually get 2 Port Status Change Events when I reset all root hub ports. I get these events on the Event Ring of interrupter 0.

The problem is I can't find out why I'm not getting interrupts generated on these events.

I'm posting a complete reproducible example here. Bootloader.c is the UEFI app that I launch from the OVMF shell by typing fs0:bootloader.efi. Bootloader.c is compiled with the EDK2 toolset. I work on Linux Ubuntu 20. Sorry for the long code.

The file main.cpp is a complete minimal reproducible example of my kernel. All the OS is compiled and launched with the 3 following scripts:

I finally got it working by inverting the MSI-X table structure found on osdev.org. I decided to completely reinitialize the xHC after leaving the UEFI environment as it could leave it in an unknown state. Here's the xHCI code for anyone wondering the same thing as me:

Time zones in toit

ANSWER

Answered 2021-Apr-25 at 07:17

toit exec runs on Toit servers, whereas toit run runs on the device.

Clearly, the two have different timezones set. The local time of devices is set to CET/CEST, and the one on servers (apparently) to UTC.

Ideally, there should be a way to set timezones on the device through a configuration file (or in the Toit console). However, that doesn't exist yet.

In the meantime there is a way to set timezones from within Toit programs. The set_tz_ function in core.time_impl makes it possible to set the TZ variable:

x86-64 Kernel crashing on setting up the IDT

Asked 2021-Apr-23 at 16:11

I am currently trying to create an x86-64 Kernel from scratch (using GRUB Multiboot2 as a bootloader). I set up my GDT just fine, but when setting up my IDT, there seems to be a problem. I isolated the issue to be my call of lidt by hlting before and after most instructions of my code. Here are my C and ASM files that define my IDT:

Your load_idt function is written as a 32-bit function where the first parameter is passed on the stack. In the 64-bit System V ABI the first parameter is passed in register RDI. Use this instead:

Laravel 8 & livewire - separate items in a row of a table

Asked 2021-Apr-20 at 11:19

i'm developing a laravel 8 application with livewire and in a page i've a table with users, the row of this table are clickable and each row also contains buttons for specific actions. I've this logic because if i click a row of the table i show a modal with data associated to the clicked row, but when i click the button on a row i've a shortcut to edid/delete/impersonate the specific user. If I click the line I get the modal open correctly, but when I click on the buttons for the shortcuts I would like only the click of the shortcut to be taken, while being associated with the line the modal also opens. Is it possible to separate this behavior? Do you have any suggestions?

The core functionality of the click passing through can't be avoided as far as know. Still, there are a few possible solutions:

You could add the modal open only to one or multiple fields in the table. For example the username. This way you avoiding the issues. Most people naturally select the first or name field, when clicking.
Assuming you set a flag to open the modal, you could try setting an internal flag for the action buttons being used very recently. When checking if the modal should be opened, you can test for this and skip opening.

Handle CPU exceptions outside of KVM

Asked 2021-Mar-16 at 13:32

I would like to trap and handle CPU exceptions outside of KVM. How can I achieve this?

...

ANSWER

Answered 2021-Mar-16 at 13:32

So, I solved this by handling the exceptions unprivileged (in usermode), and simply trap into the hypervisor using any method of doing such, like writing to a trapping MMIO address. In my case the guest is always unprivileged and can't modify its own pagetables, so the host will be setting everything up before entering the guest.

This works completely fine, however backtraces will need to be handled remotely.

For the makeidt: routine; I think you've got "endianness" (or byte or word order?) all mixed up. E.g. "lowest 16 bits of offset" should end up in the lowest 16 bits of edx (which is where it was in the input parameter to begin with) but you're treating it as "highest 16 bits of offset".

What you want would be more like (untested, NASM syntax):
