* microblaze: mb: remove use of seq_printf return valueJoe Perches2015-04-151-76/+73
| | | | | | | | | | | | | The seq_printf return value, because it's frequently misused, will eventually be converted to void. See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to seq_has_overflowed() and make public") Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Michal Simek <monstr@monstr.eu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* microblaze: Standardise cpuinfo output for cache policyJohn A. Williams2011-07-251-2/+3
| | | | | | | The current cpuinfo output for the cache policy has no leading tag:, making it difficult to parse. Add a leaning "Dcache-policy:" tag to this field. Signed-off-by: John A. Williams <john.williams@petalogix.com>
* microblaze: Unprivileged stream instruction awarenessJohn A. Williams2011-07-251-0/+4
| | | | | | | | | | | Add cpuinfo support for the new MicroBlaze option permitting userspace (unprivileged) access to the streaming instructions (FSL / AXI-stream). Emit a noisy warning at bootup if this is enabled, because bad user code can potentially lockup the CPU. Signed-off-by: John A.

* microblaze: Add PVR for endians plus detectionMichal Simek2010-10-211-1/+2
| | | | | | | Upcomming microblaze version will support little-endian. Signed-off-by: Michal Simek <monstr@monstr.eu> Acked-by: Grant Likely <grant.likely@secretlab.ca>
* microblaze: Allow PAGE_SIZE configurationSteven J. Magnani2010-08-041-0/+1
| | | | | | | | | | Allow developer to configure memory page size at compile time. Larger pages can improve performance on some workloads. Based on PowerPC code. Signed-off-by: Steven J. Magnani <steve@digidescorp.com> Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: cpuinfo shows cache line lengthMichal Simek2010-05-061-4/+6
| | | | | | Show cache line length in /proc/cpuinfo. Signed-off-by: Michal Simek <monstr@monstr.eu>
* microblaze: Extend cpuinfo for support write-back cachesMichal Simek2009-12-141-2/+6
| | | | | | | There is missing checking agains PVR but this is not important for now. There are some missing checking too. Signed-off-by: Michal Simek <monstr@monstr.eu>
