Allocate more RAM to executable

wish of those help RAM doesn't make things go faster. RAM is just there to store data your program uses; if it's not using much then it doesn't need much.
Similarly, in terms of CPU usage, the program will use everything it can (the operating system can change priority, and there are APIs for that, but this is probably not your issue).

How to allocate an executable page in a Linux kernel module?

wish helps you I'm writing a Linux kernel module, and I'd like to allocate an executable page. Plain kmalloc() returns a pointer within a non-executable page, and I get a kernel panic when executing code there. It has to work on Ubuntu Karmic x86, 2.6.31-20-generic-pae.
code :
#include <linux/vmalloc.h>
#include <asm/pgtype_types.h>
char *p = __vmalloc(byte_size, GFP_KERNEL, PAGE_KERNEL_EXEC);
if (p != NULL) vfree(p);

To fix this issue See mprotect(). Once you have filled a (n-)page-sized memory region (allocated with mmap()) with code, change its permissions to disallow writes and allow execution.

Component unable to allocate device that is not Executable Device

I wish this helpful for you Although your device is capable of satisfying the usesdevice allocation, without a GPP or other ExecutableDevice, there is no place to run your component. There are two ways that allocation is performed when launching components:
Satisfying usesdevice relationships Deciding on which device to deploy the executable

Why can I allocate a local variable and fread to it, but segfault if I try to allocate a pointer in a struct and read to

I wish did fix the issue. I'm playing with a small C program to brush up. I have the following struct... , First you do
code :
thisAddress->name = malloc(len);
thisAddress->email = malloc(len);
rc = fread(thisAddress, sizeof(struct Address), 1, conn->file);

Is there a way to allocate memory in a .NET process that is "executable"?

should help you out This is a task for the VirtualAlloc and VirtualProtect API calls rather than the interop marshaller. You will have to declare them [DllImport]. Hhowever this entire process would be painful enough that I would seriously consider using a different language. Perhaps a c++ project that provides just the interop calls you need while the UI remains in C#. (Honestly, interop stuff is the only area where I see c++ and .net working well together).
