| | | | | | | | | | | | | | | | | | | | | | | | The CONFIG_PPC_OF symbol is used to mean that the firmware device tree access functions are available. Since we always have a device tree with ARCH=powerpc, make CONFIG_PPC_OF always Y for ARCH=powerpc. This fixes some compile errors reported by Kumar Gala, but in a different way to his patch. This also makes prom_parse.o be compiled only if CONFIG_PPC_OF so that non-OF ARCH=ppc platforms will compile. Signed-off-by: Paul Mackerras <paulus@samba.org>

| * [PATCH] 4/5 powerpc: Add cpufreq support for all desktop G5Benjamin Herrenschmidt2006-01-091-47/+449
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds cpufreq support for all desktop "tower" G5 models. The only G5 models still lacking cpufreq support at this point are the Xserve and possibly the new iMac iSight (not tested). I'll have those added soon. That patch uses the new platform functions interpreter to implement frequency and voltage switching on most models. Note that in order to find the low frequency value, I had to hack something that might now work properly on all models, so if the frequency value reported when running low speed looks bogus to you, please report it to me. (Appart from a bogus reported value, things should work fine). Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] 3/5 powerpc: Add platform functions interpreterBenjamin Herrenschmidt2006-01-0910-42/+2028
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the platform function interpreter itself along with the backends for UniN/U3/U4, mac-io, GPIOs and i2c. It adds the ability to execute those do-platform-* scripts in the device-tree (at least for most devices for which a backend is provided). This should replace the clock spreading hacks properly. It might also have an impact on all sort of machines since some of the scripts marked "at init" will now be executed on boot (or some other on sleep/wakeup), those will possibly do things that the kernel didn't do at all, like setting some values into some i2c devices (changing thermal sensor calibration or conversion rate) etc... Thus regression testing is MUCH welcome. Also loook for errors in dmesg. That's also why I've left rather verbose debugging enabled in this version of the patch. (I do expect some Windtunnel G4s to show some errors as they have an i2c clock chip on the PMU bus that uses some primitives that the i2c backend doesn't implement yet. I really need users that have one of those machine to come back to me so we can get that done right, though the errors themselves should be harmless, I suspect the machine might not run at full speed).

| * [PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt2006-01-0912-1364/+563
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] 1/5 powerpc: Rework PowerMac i2c part 1Benjamin Herrenschmidt2006-01-0911-667/+859
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first part of a rework of the PowerMac i2c code. It completely reworks the "low_i2c" layer. It is now more flexible, supports KeyWest, SMU and PMU i2c busses, and provides functions to match device nodes to i2c busses and adapters. This patch also extends & fix some bugs in the SMU driver related to i2c support and removes the clock spreading hacks from the pmac feature code rather than adapting them to the new API since they'll be replaced by the platform function code completely in patch 3/5 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] ppc64: fix time syscallAnton Blanchard2006-01-092-29/+1
| | | | | | | | | | | | | | | | | | | | | | | | ppc64 has its own version of sys_time. It looks pretty scary, touching a whole bunch of variables without any locking or memory ordering. In fact, a recent bugreport has shown it can actually go backwards. Time to remove it and just use the generic sys_time, which is implemented on top of do_gettimeofday.

| * [PATCH] ppc32: Put cache flush routines back into .relocate_code sectionPaul Janzen2006-01-091-2/+4

However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem. I could easily be convinced that the _GLOBAL definition should be modified to remove the ".text;" line either instead of, or in addition to, this fix.

| * [PATCH] spufs: set irq affinity for running threadsArnd Bergmann2006-01-095-16/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For far, all SPU triggered interrupts always end up on the first SMT thread, which is a bad solution. This patch implements setting the affinity to the CPU that was running last when entering execution on an SPU. This should result in a significant reduction in IPI calls and better cache locality for SPE thread specific data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a hypervisor based setup, direct access to the first priviledged register space can typically not be allowed to the kernel and has to be implemented through hypervisor calls. As suggested by Masato Noguchi, let's abstract the register access trough a number of function calls. Since there is currently no public specification of actual hypervisor calls to implement this, I only provide a place that makes it easier to hook into.

| | | | | | | | | | | | | | | | In setup_arch and setup_system call find_legacy_serial_ports() if we build in support for 8250 serial ports instead of basing it on PPC_MULTIPLATFORM. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] powerpc: added a udbg_progressKumar Gala2006-01-093-7/+8
| | | | | | | | | | | | | | Added a common udbg_progress for use by ppc_md.progress() Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * [PATCH] powerpc: Add the ability to handle SOC ports in legacy_serialKumar Gala2006-01-091-10/+52
| | | | | | | | | | | | | | | | | | Add the ability to configure and initialize legacy 8250 serials ports on an SOC bus. Also, fixed an issue that we would not configure any serial ports if "linux,stdout-path" was not found.

| * [PATCH] powerpc: Loosen udbg_probe_uart_speed sanity checkingKumar Gala2006-01-091-1/+1
| | | | | | | | | | | | | | | | | | The checking of the baudrate in udbg_probe_uart_speed was too tight and would cause reporting back of the default baud rate in cases where the computed speed was valid.

| * [PATCH] powerpc: don't add memory to empty node/zoneMike Kravetz2006-01-091-5/+14
| | | | | | | | | | | | | | | | | | | | | | The system will oops if an attempt is made to add memory to an empty node/zone. This patch prevents adding memory to an empty node. The code to dynamically add a node/zone is non-trivial. This patch is temporary and will be removed when the ability to dynamically add a node/zone is complete.

| * [PATCH] powerpc: sanitize header files for user space includesArnd Bergmann2006-01-0975-29/+183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | include/asm-ppc/ had #ifdef __KERNEL__ in all header files that are not meant for use by user space, include/asm-powerpc does not have this yet. This patch gets us a lot closer there. There are a few cases where I was not sure, so I left them out. I have verified that no CONFIG_* symbols are used outside of __KERNEL__ any more and that there are no obvious compile errors when including any of the headers in user space libraries.
