Subject: Allocation of kernel memory >128K
Date: Tue, 11 Dec 2001 15:36:46 +0530 (IST) [thread overview]
Message-ID: <Pine.LNX.4.21.0112111531110.5038-100000@mailhost.tifr.res.in> (raw)
I have been working on a module in which I copy large amount of data fromn
the user to the kernel area.To do so I allocate using either kmaaloc or
vmalloc or get_free_pages()large amount of memory(in the range of
MBytes) in the kernel space.However this attempt is not successful.One ofmy
colleagues informed me that in the kernel space it is safe not to allocate
large amount of memory at one time,should be kept upto 30K...is he
right....could you throw more light on this issue.
Thanking you,
Amit Jain
