I'm learning OpenGL following this video. While it's based on C++, I attempt to use Kotlin instead with lwjgl. As I code and run this:
// Something above
stbi_set_flip_vertically_on_load(true)
val width = IntBuffer.allocate(1)
val height = IntBuffer.allocate(1)
val colorChannel = IntBuffer.allocate(1)
val imageBuffer = stbi_load(
"src/main/resources/$filePath",
width, height,
colorChannel, 0
) ?: throw NoSuchElementException(filePath)
// Something below
It explodes on stbi_load() outside JVM with the following error message:
#

The image is here(png, 512px), and I've saved it in the (maybe) correct place as the code shows.
So what is going on in the native environment? :(
LWJGL 3 does not support on-heap (i.e. non-direct) NIO Buffers when talking to a native library like stb_image. Non-direct/on-heap NIO Buffers are those that are wrappers of a Java byte array.
With LWJGL 3 you always need to use off-heap (i.e. direct) NIO Buffers.
See https://docs.oracle.com/javase/7/docs/api/java/nio/ByteBuffer.html#direct for a further explanation of the differences.
So, instead of
IntBuffer.allocate(1)
you should use:
ByteBuffer.allocateDirect(4).asIntBuffer()
Also you should configure the NIO Buffer to use the same endianness as your platform, since otherwise you will read garbage out of the buffer later (the default endianness of all NIO Buffers is network-byte-order i.e. big endian):
ByteBuffer.allocateDirect(4).order(ByteOrder.nativeOrder()).asIntBuffer()
and since the above is quite a mouthfull, LWJGL 3 provides a BufferUtils class with simple wrappers, like:
BufferUtils.createIntBuffer(1)
to achieve the same as above.
And last but not least, doing correct and efficient memory management in LWJGL 3 is more involved, because in this particular case, you'd be better off using a MemoryStack.
See: https://blog.lwjgl.org/memory-management-in-lwjgl-3/

The first load begin at offset 0x000000 and the size is 0x4ca8e6. why the second offset not (0x000000 + 0x4ca8e6), I see the (0x4cb000 - 0x4ca8e6) content, all 0. I can't get it. What the rule about the offset in file?
The first load begin at offset 0x000000 and the size is 0x4ca8e6. why the second offset not (0x000000 + 0x4ca8e6)
Because the loader mmaps LOAD segments directly into memory, for each LOAD segment the following must be true: (p_vaddr - p_offset) % page_size == 0.
On x86_64 the maximum page size is 2MiB (0x200000). This places severe restriction on the second (and subsequent) LOAD segment location.
I'm running qemu-system-x86_64 with my new pci device. And i want to use IRQ 17 (Since driver from kernel listen for IRQ 17). But my PCI device take IRQ 10 or 11. base on interrupt_pin(A,B,C,E).
Then i want to send irq to kernel module by qemu_irq_pulse.
This is how i allocate irq:
pci_config_set_interrupt_pin(pci_dev->config, 1);
d->irq = pci_allocate_irq(pci_dev)

Interrupt: pin A routed to IRQ 10
Capabilities: [80] MSI: Enable- Count=1/1 Maskable- 64bit+
Address: 0000000000000000 Data: 0000
Kernel driver failed to request irq since it trying to attach to IRQ 17. I don't want to change kernel side.
This is what i want to see:
root#hostname:~# cat /proc/interrupts
CPU0
0: 2213 IO-APIC
17: 0 IO-APIC 17-fasteoi some_kernel_driver_name
How to allocate interrupt 17 for PCI device in qemu?
Im not sure it is correct answer but for me it helps:
Add to ACPI:
irqs = 17;
aml_append(crs, aml_interrupt(AML_CONSUMER, AML_EDGE,
AML_ACTIVE_HIGH, AML_SHARED,
&irqs, 1));
Also PCI interrupt number looks like somehow depends on PCI vendor_id and device_id.
I try to write a program to generate ELF(based on Arm and execute through qemu-arm). Most format in ELF has been well illustrated
on wiki. But I can't find any spec describe the format of special section(e.g. .text .data(especially what I want to know)).
I tried to put some initialized global variable in .data section. What format should I write in ELF(.data section) if I have global statement like: int a = 10;
There is not special format for .text and .data.
When the static linker links several .o file,
it simply concatenates the .text and .data segments (while resolving relocations)
and places them in the final .so or executable file according to the linker script (see gcc -Wl,-verbose /dev/null).
The .data segment simply contains the initial values of the instanciated global variables.
The .text segment simply contains the machine code of the routines/functions.
Let's take this simple C file:
char x[5] = {0xba, 0xbb, 0xbc, 0xbd, 0xbe};
char f(int i) {
return x[i];
}
Let's compile it:
$ gcc -c -o test.o test.c
Let's dump the .data section, using elfcat:
$ elfcat test.o --section-name .data | xxd
00000000: babb bcbd be .....
We can clearly explain the content of .data section.
Let's dump the .text section:
$ elfcat test.o --section-name .text | xxd
00000000: 5548 89e5 897d fc8b 45fc 4898 488d 1500 UH...}..E.H.H...
00000010: 0000 000f b604 105d c3
Let's decompile this:
$ elfcat test.o --section-name .text > test.text
$ r2 -a x86 -b 64 -qc pd test.text
0x00000000 55 push rbp
0x00000001 4889e5 mov rbp, rsp
0x00000004 897dfc mov dword [rbp - 4], edi
0x00000007 8b45fc mov eax, dword [rbp - 4]
0x0000000a 4898 cdqe
0x0000000c 488d15000000. lea rdx, qword [0x00000013] ; 19
0x00000013 0fb60410 movzx eax, byte [rax + rdx]
0x00000017 5d pop rbp
0x00000018 c3 ret
Again, there is nothing special in the text segment: it only contains the machine code of the routines/functions of my program.
Notice however the relocation and symbol informations in other segments:
$ readelf -a test.o
[ ... ]
Relocation section '.rela.text' at offset 0x1b8 contains 1 entry:
Offset Info Type Sym. Value Sym. Name + Addend
00000000000f 000800000002 R_X86_64_PC32 0000000000000000 x - 4
Relocation section '.rela.eh_frame' at offset 0x1d0 contains 1 entry:
Offset Info Type Sym. Value Sym. Name + Addend
000000000020 000200000002 R_X86_64_PC32 0000000000000000 .text + 0
[...]
Symbol table '.symtab' contains 10 entries:
Num: Value Size Type Bind Vis Ndx Name

I want to detect which mode I just using now with BIOS intXX when running bootloader I wrote.
How to detect now is text mode or graphics mode?
Which interrupt function I should use?
Thank you~
I didn't figure out why when I run int 10 ,the value of AL doesn't change.
