Subject: Question about pte_alloc()
Date: Wed, 15 Nov 2000 02:07:38 -0500 [thread overview]
Message-ID: <3A12363A.3B5395AF@cse.iitkgp.ernet.in> (raw)
hi all,
it appears from the code that pte_alloc() might block since it allocates
a page table with GFP_KERNEL if the page table doesnt already exist. i
need to call pte_alloc() at interrupt time. Basically i want to map some
kernel memory into user space as soon as the device gives me data. will
there be any problem if i use another version of pte_alloc() which calls
with GFP_ATOMIC priority?
Maybe i am completely lost :-)
cheers
joy
