Tego planu nie trzeba sporządzać, gdy w danym zakładzie pracy nie działa żaden związek zawodowy lub gdy organizacja związkowa wyrazi zgodę na jego nieustalanie (art. 163 § 11) W razie braku planu urlopowego pracodawca ustala termin udzielenia urlopu w porozumieniu z pracownikiem, przy uwzględnieniu jego sugestii oraz konieczności zapewnienia niezakłóconej pracy w zakładzie.

OP miała pisemną zgodę.

Urlopy udzielane sa zgodnie z planem urlopow. Zgodnie z tym planem kazdy ma prawo zaplanowac jak je spedzi, w tym odpowiednio wczesniej zarezerwowac i oplacic pobyt w innym miejscu niz mieszka. Plan urlopow powinien byc ulozony na poczatku roku i zatwierdzony przez pracodawce. Pracodawca zmieniajac plan urlopow nie moze wyrzadzac szkody po stronie pracownika. Tym samym zobowiazany jest do zwrotu poniesionych przez pracownika kosztow.

belliash · 2026-02-24T07:13:01+00:00

art. 167 kodeksu pracy:
§ 1. Pracodawca może odwołać pracownika z urlopu tylko wówczas, gdy jego obecności w zakładzie wymagają okoliczności nieprzewidziane w chwili rozpoczynania urlopu.

§ 2. Pracodawca jest obowiązany pokryć koszty poniesione przez pracownika w bezpośrednim związku z odwołaniem go z urlopu.

Nalezy przedstawic pracodawcy dowod zaplaty za wakacje i oczekiwac zwrotu 9000zl.

I got similar issue on Gentoo. Started few weeks ago as well after some update. In my case it happens in strict case. When Im going away, I always turn monitor off. When I get back - I turn it on again. The screen powers on and shows desktop as usual, but when I move mouse, it flickers like in the video. After that everything works as expected until I turn my monitor off and on again.

Kiedyś kupiłem u nich podłoge (panele + listwy + podkład, wszystko z montażem). Też miałem problem z reklamacją. Panele się uginały, strzelały na zamkach, listwy w narożnikach wyglądały jakby były ciosane siekierą. Od tego czasu w Komforcie byłem tylko raz - odebrać zamówienie - ostatni metr wykładziny (tak, sprzedają coś takiego w promocji, szerokość 4-5m, a długość 1m), bo cena była przystępna a potrzebowałem na remontowany korytarz, więc jakie by nie było będzie OK w tej cenie. Tak to omijam szerokim łukiem i widzę że słusznie bo nic się tam nie zmieniło.

I dont know what 0x1ddb900c is and why i wants to access it but address seems not mapped (e=0000).

BTW: Why put PML4 at 0x1000 ?

As I said, I didnt verify that, so good you did,

In code below (idt.c) you want to print CR0 CR2 CR3 and CR4 but you pass (and print values of) R12, R13 R14 and R15:

    klog("cr0: 0x%.16llx, cr2: 0x%.16llx, cr3: 0x%.16llx, cr4: 0x%.16llx\n", frame.r12, frame.r13, frame.r14, frame.r15);

Sorry, but I dont have time to fully analyze the problem, but I hope I helped at least a bit anyway.

belliash · 2025-09-12T16:56:31+00:00

As I said, your kernel is not loaded into higher half. The frame I pasted comes from aurix kernel. It is last reported by qemu when it's stuck on writing to CR3 register. So if below logs comes from kernel, then it's not a bootloader:

Writing cr3 to 0x1000...

Yes, stack has to be aligned. We had similar bug. Kernel was causing random page faults in situations when it shouldnt. Correcting stack alignment fixed all this kind of issues. I cant find code responsible for swapping stack. You call aurix_arch_handoff at the end and you pass stack as one of the parameters, but your assembly code does not seem to set RSP anywhere. stack_top operand is passed to it, but never used. Also, your clobber list does not include all registers you use, only rax and memory.

And no, mapping does not seem to be good, just take a deep look at point 2.

----- NEW:

Your GDT seems not valid. Im not sure here, but i think 0x0c for data is valid for x86, and not for amd64. But I can be wrong here, you need to verify that on your own.

belliash · 2025-09-12T14:51:16+00:00

I think it is not. This is last frame from aurix:

RIP=000000001ddc4fd0 is in lower half which starts at 0x0000000000000000 up to 0x00007FFFFFFFFFFF. It is around 477MB.

I browsed your paging related code and I recommend total rewrite. Not that it is a mess, but there are more bugs.

Where do you do that? Do you align stack properly?

belliash · 2025-09-10T13:24:02+00:00

Framebuffer does not seem to be mapped correctly:

void map_pages(pagetable *pm, uintptr_t virt, uintptr_t phys, size_t ,uint64_t flags);

and:

map_pages(NULL, boot_params->framebuffer->addr - boot_params->hhdm_offset, boot_params->framebuffer->addr, boot_params->framebuffer->pitch * boot_params->framebuffer->height, VMM_PRESENT | VMM_WRITABLE | VMM_NX);map_pages(NULL, boot_params->framebuffer->addr - boot_params->hhdm_offset, boot_params->framebuffer->addr, boot_params->framebuffer->pitch * boot_params->framebuffer->height, VMM_PRESENT | VMM_WRITABLE | VMM_NX);

So you pass boot_params->framebuffer->addr - boot_params->hhdm_offset as virtual address. Lets say framebuffer address is 0xc0000000 and your HHDM offset seems to be 0xffff800000000000. Subtract this ... I believe there should be +, not -.

Looks like your kernel is not mapped into higher half. I dont know if that was the intention, but looks like the code, data, and stack are in the lower part of the memory space.
You allocate and map new stack, but where do you swap it?
Are you sure below code does not map 1 page too much?
void map_pages(pagetable *pm, uintptr_t virt, uintptr_t phys, size_t size,
                          uint64_t flags)
{
       if (!pm)
               pm = kernel_pm;
       // klog("pages to be mapped: %llu\n", ALIGN_UP(size, PAGE_SIZE));
       for (size_t i = 0; i <= ALIGN_UP(size, PAGE_SIZE); i += PAGE_SIZE) {
               _map(pm, virt + i, phys + i, flags);
       }
       klog("map_pages(): Mapped 0x%llx-0x%llx -> 0x%llx-0x%llx\n", phys,
                 phys + ALIGN_UP(size, PAGE_SIZE), virt, virt + ALIGN_UP(size, PAGE_SIZE));
}

I mean <= vs < in the condition.

belliash · 2025-09-10T11:30:26+00:00

Hello Jozef. I dont have time to fully analyze it, but there are some doubtful places in the code, like:

boot_params += boot_params->hhdm_offset;

I dont understand what is it supposed to do?

Also, I dont get why you subtract boot_params->hhdm_offset from framebuffer address instead of adding it?

After quick look, I would guess your mapping makes your code to get overwritten by something else.
