[ofw] RE: Make all funcions no-pagable?

[Fab Tillier]

You can also use MmLockPagableCodeSection to page in and lock the specified code regions.  You can call this when you detect the parent device is not pagable (the device object's Flags parameter does not have the DO_POWER_PAGEABLE bit set).

Hi James,

Please prepare a patch that removes all the #pragma alloc_text from the code and we will apply it.

Thanks
Tzachi & Leonid

Hi,

We discussed this topic before. Today I saw system hangs during shutdown again. This time function __restore_pci_config caused the page out problem and stopped forever. Attached is the stack.

Is there any simple way to disable all the page pragma? Or we have to go to each line the take them out?
#pragma alloc_text (PAGE, __restore_pci_config).

Thanks,
James
