2010-02-23sh: wire up SET/GET_UNALIGN_CTL.Paul Mundt4-2/+51
This hooks up the SET/GET_UNALIGN_CTL knobs cribbing the bulk of it from the PPC and ia64 implementations. The thread flags happen to be the logical inverse of what the global fault mode is set to, so this works out pretty cleanly. By default the global fault mode is used, with tasks now being able to override their own settings via prctl(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-02-22resource/PCI: mark struct resource as constDominik Brodowski1-1/+1

2010-02-22sh: always enable sh7724 vpu_clk and set to 166MHz on EcovecMagnus Damm2-1/+6
Update the sh7724 processor code to always enable vpu_clk. On the Ecovec board, set the vpu_clk to 166 Mhz. The 166MHz setting results in a divide-by-6 setup for vpu_clk and improves the VPU performance compared to the power-on-reset/bootloader configuration.

2010-02-22sh: add sh7724 kick callback to clk_div4_tableMagnus Damm3-0/+16
This patch adds a ->kick() callback to clk_div4_table and ties it into sh_clk_div4_set_rate(). A sh7724 specific kick function is also added that updates the KICK bit whenever div4 clocks in FRQCRA and FRQCRB have been set. Allows us to set the VPU clock.

2010-02-18sh: Merge legacy and dynamic PMB modes.Paul Mundt10-71/+276
This implements a bit of rework for the PMB code, which permits us to kill off the legacy PMB mode completely. Rather than trusting the boot loader to do the right thing, we do a quick verification of the PMB contents to determine whether to have the kernel setup the initial mappings or whether it needs to mangle them later on instead. If we're booting from legacy mappings, the kernel will now take control of them and make them match the kernel's initial mapping configuration. This is accomplished by breaking the initialization phase out in to multiple steps: synchronization, merging, and resizing. With the recent rework, the synchronization code establishes page links for compound mappings already, so we build on top of this for promoting mappings and reclaiming unused slots. At the same time, the changes introduced for the uncached helpers also permit us to dynamically resize the uncached mapping without any particular headaches. The smallest page size is more than sufficient for mapping all of kernel text, and as we're careful not to jump to any far off locations in the setup code the mapping can safely be resized regardless of whether we are executing from it or not. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-18sh: Use uncached I/O helpers in PMB setup.Paul Mundt1-27/+19
The PMB code is an example of something that spends an absurd amount of time running uncached when only a couple of operations really need to be. This switches over to the shiny new uncached helpers, permitting us to spend far more time running cached. Additionally, MMUCR twiddling is perfectly safe from cached space given that it's paired with a control register barrier, so fix that up, too. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-18sh: Provide uncached I/O helpers.Paul Mundt1-0/+22
There are lots of registers that can only be updated from the uncached mapping, so we add some helpers for those cases in order to make it easier to ensure that we only make the jump when it's absolutely necessary. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-17sh: PMB locking overhaul.Paul Mundt2-56/+114
This implements some locking for the PMB code. A high level rwlock is added for dealing with rw accesses on the entry map while a per-entry data structure spinlock is added to deal with the PMB entry changing out from underneath us. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-17tracing: Unify arch_syscall_addr() implementationsMike Frysinger2-9/+2
Most implementations of arch_syscall_addr() are the same, so create a default version in common code and move the one piece that differs (the syscall table) to asm/syscall.h. New arch ports don't have to waste time copying & pasting this simple function. The s390/sparc versions need to be different, so document why.

2010-02-17sh: Fix up dynamically created write-through PMB mappings.Paul Mundt1-24/+32
Write-through PMB mappings still require the cache bit to be set, even if they're to be flagged with a different cache policy and bufferability bit. To reduce some of the confusion surrounding the flag encoding we centralize the cache mask based on the system cache policy while we're at it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-17sh: Build PMB entry links for existing contiguous multi-page mappings.Paul Mundt2-31/+30
This plugs in entry sizing support for existing mappings and then builds on top of that for linking together entries that are mapping contiguous areas. This will ultimately permit us to coalesce mappings and promote head pages while reclaiming PMB slots for dynamic remapping. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-17sh: uncached mapping helpers.Paul Mundt6-30/+58
This adds some helper routines for uncached mapping support. This simplifies some of the cases where we need to check the uncached mapping boundaries in addition to giving us a centralized location for building more complex manipulation on top of. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-17sh: PMB tidying.Paul Mundt3-47/+42
Some overdue cleanup of the PMB code, killing off unused functionality and duplication sprinkled about the tree. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-17sh: Fix up more 64-bit pgprot truncation on SH-X2 TLB.Paul Mundt5-12/+17
Both the store queue API and the PMB remapping take unsigned long for their pgprot flags, which cuts off the extended protection bits. In the case of the PMB this isn't really a problem since the cache attribute bits that we care about are all in the lower 32-bits, but we do it just to be safe. The store queue remapping on the other hand depends on the extended prot bits for enabling userspace access to the mappings. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-02-17sh: Setup boot CPU VBR early to enable early page faults.Paul Mundt2-11/+17
vmemmap and the vmsplit code amongst others need to be able to take page faults much earlier than trap_init() time, so move this in to the early CPU initialization. VBR setup for secondary CPUs is already handled through start_secondary(), so we only need to do this for the boot CPU. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-16sh: Kill off some superfluous legacy PMB special casing.Paul Mundt2-10/+4
The __va()/__pa() offsets and the boot memory offsets are consistent for all PMB users, so there is no need to special case these for legacy PMB. Kill the special casing off and depend on CONFIG_PMB across the board. This also fixes up yet another addressing bug for sh64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-16sh: Merge the legacy PMB mapping and entry synchronization code.Paul Mundt2-93/+70
This merges the code for iterating over the legacy PMB mappings and the code for synchronizing software state with the hardware mappings. There's really no reason to do the same iteration twice, and this also buys us the legacy entry logging facility for the dynamic PMB case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-02-16sh: Prevent fixed slot PMB remapping from clobbering boot entries.Paul Mundt1-1/+1
The PMB initialization code walks the entries and synchronizes the software PMB state with the hardware mappings, preserving the slot index. Unfortunately pmb_alloc() only tested the bit position in the entry map and failed to set it, resulting in subsequent remaps being able to be dynamically assigned a slot that trampled an existing boot mapping with general badness ensuing.

2010-02-15sh64: fix tracing of signals.Paul Mundt2-3/+12
This follows the parisc change to ensure that tracehook_signal_handler() is aware of when we are single-stepping in order to ptrace_notify() appropriately. While this was implemented for 32-bit SH, sh64 neglected to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code, resulting in ptrace_notify() never being called. As sh64 uses all of the other abstractions already, this simply plugs in the thread flag in the appropriate enable/disable paths and fixes up the tracehook notification accordingly. With this in place, sh64 is brought in line with what 32-bit is already doing. Reported-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
