2009-06-02sh: add weak l2_cache_init function.Kuninori Morimoto1-0/+7
Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-12-22sh: Move arch_get_unmapped_area() in to arch/sh/mm/mmap.c.Paul Mundt1-0/+2
Now that arch/sh/mm/mmap.c exists, move arch_get_unmapped_area() there. Follows the ARM change. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-03-06sh: Fix up section mismatches.Paul Mundt1-1/+1
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Encode L1/L2 cache shape in auxvt.Paul Mundt1-1/+28
This adds in the L1I/L1D/L2 cache shape support to their respective entries in the ELF auxvt, based on the Alpha implementation. We use this on the userspace libc side for calculating a tightly packed SHMLBA amongst other things. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Preparation for uncached jumps through PMB.Stuart Menefy1-3/+3
Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.

2008-01-28sh: Disable initial cache flush on SH-5.Paul Mundt1-14/+18
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-01-28sh: Don't reference UBC code in CPU init on sh64.Paul Mundt1-1/+6
Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-09-21sh: Bring SMP support back from the dead.Paul Mundt1-5/+11
There was a very preliminary bunch of SMP code scattered around for the SH7604 microcontrollers from way back when, and it has mostly suffered bitrot since then. With the tree already having been slowly getting prepped for SMP, this plugs in most of the remaining platform-independent bits.

2007-09-21sh: Support explicit L1 cache disabling.Paul Mundt1-4/+7
This reworks the cache mode configuration in Kconfig, and allows for explicit selection of write-back/write-through/off configurations. All of the cache flushing routines are optimized away for the off case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-06-11sh: Tidy up dependencies for SH-2 build.Paul Mundt1-14/+1
SH-2 can presently get in to some pretty bogus states, so we tidy up the dependencies a bit and get it all building again. This gets us a bit closer to a functional allyesconfig and allmodconfig, though there are still a few things to fix up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-05-07sh: speculative execution support for SH7780.Paul Mundt1-0/+19
SH7780 has a speculative execution mode where it can speculatively perform an instruction fetch for subroutine returns, this allows it to be enabled. There are some various pitfalls associated with this mode, so it's left as depending on CONFIG_EXPERIMENTAL and not enabled by default. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-03-12sh: Fix SH-3 cache entry_mask and way_size calculation.Paul Mundt1-3/+17
The code for performing the calculation was only in the SH-4 probe path, move it out to the common path so the other parts get this right too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Fixup cpu_data references for the non-boot CPUs.Paul Mundt1-15/+15
There are a lot of bogus cpu_data-> references that only end up working for the boot CPU, convert these to current_cpu_data to fixup SMP. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2007-02-13sh: Use a per-cpu ASID cache.Paul Mundt1-2/+9
Previously this was implemented using a global cache, cache this per-CPU instead and bump up the number of context IDs to match NR_CPUS. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-12-06sh: Add support for SH7206 and SH7619 CPU subtypes.Yoshinori Sato1-0/+2
This implements initial support for the SH7206 (SH-2A) and SH7619 (SH-2) MMU-less CPUs. Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Calculate shm alignment at runtime.Paul Mundt1-0/+5
Set the SHM alignment at runtime, based off of probed cache desc. Optimize get_unmapped_area() to only colour align shared mappings. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-09-27sh: Optimized cache handling for SH-4/SH-4A caches.Richard Curnow1-1/+15
This reworks some of the SH-4 cache handling code to more easily accomodate newer-style caches (particularly for the > direct-mapped case), as well as optimizing some of the old code. Signed-off-by: Richard Curnow <richard.curnow@st.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2006-03-31[PATCH] Don't pass boot parameters to argv_init[]OGAWA Hirofumi1-1/+1
The boot cmdline is parsed in parse_early_param() and parse_args(,unknown_bootoption). And __setup() is used in obsolete_checksetup(). start_kernel() -> parse_args() -> unknown_bootoption() -> obsolete_checksetup() If __setup()'s callback (->setup_func()) returns 1 in obsolete_checksetup(), obsolete_checksetup() thinks a parameter was handled. If ->setup_func() returns 0, obsolete_checksetup() tries other ->setup_func(). If all ->setup_func() that matched a parameter returns 0, a parameter is seted to argv_init[]. Then, when runing /sbin/init or init=app, argv_init[] is passed to the app. If the app doesn't ignore those arguments, it will warning and exit. This patch fixes a wrong usage of it, however fixes obvious one only.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+222
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
