Raw Normal View History

Linux-2.6.12-rc2 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!

Convert files to UTF-8 and some cleanups * Convert files to UTF-8. * Also correct some people's names (one example is Eißfeldt, which was found in a source file. Given that the author used an ß at all in a source file indicates that the real name has in fact a 'ß' and not an 'ss', which is commonly used as a substitute for 'ß' when limited to 7bit.) * Correct town names (Goettingen -> Göttingen) * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313) Signed-off-by: Jan Engelhardt <jengelh@gmx.de> Signed-off-by: Adrian Bunk <bunk@kernel.org>

#include <linux/list.h>
include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

/* setup & interrupt */
IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

Various drivers' irq handlers: kill dead code, needless casts - Eliminate casts to/from void* - Eliminate checks for conditions that never occur. These typically fall into two classes: 1) Checking for 'dev_id == NULL', then it is never called with NULL as an argument. 2) Checking for invalid irq number, when the only caller (the system) guarantees the irq handler is called with the proper 'irq' number argument.

[SCSI] aha152x: preliminary fixes and some comments hunk by hunk: - CHECK_CONDITION is what happens to cmnd->status >> 1 or after status_byte() macro. But here it is used directly on status which means 0x1 which is an undefined bit in the standard. And is a status that will never return from a target. - in busfree_run at the DONE_SC phase we have 3 distinct operation: 1-if(DONE_SC->SCp.phase & check_condition) The REQUEST_SENSE command return. - Restore original command - Than continue to operation 3. 2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION) A regular command returned with a status. - Internally re-Q a REQUEST_SENSE. - Do not do operation 3. 3- - Complete the command and return it to scsi-ml So the 0x2 in both these operations (1,2) means the scsi check-condition status, hence SAM_STAT_CHECK_CONDITION - Here the code asks about !(DONE_SC->SCp.Status & not_issued) but "not_issued" is an enum belonging to the "phase" member and not to the Status returned from target. The reason this works is because not_issued==1 and Also CHECK_CONDITION==1 (remember from hunk 1). So actually the code was asking !(DONE_SC->SCp.Status & CHECK_CONDITION). Which means "Has the status been read from target yet?" Staus is read at status_run(). "not_issued" is cleared in seldo_run() which is usually earlier than status_run(). So this patch does nothing as far as assembly is concerned but it does let the reader understand what is going on.

This means drivers can easily get at it and misuse it. Due to the old_ naming this doesn't happen for most of them, but two that have different names have been used wrong a lot (see previous patch). Another downside is that they unessecarily bloat the scsi_cmnd size.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

And is a status that will never return from a target. - in busfree_run at the DONE_SC phase we have 3 distinct operation: 1-if(DONE_SC->SCp.phase & check_condition) The REQUEST_SENSE command return. - Restore original command - Than continue to operation 3. 2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION) A regular command returned with a status. - Internally re-Q a REQUEST_SENSE. - Do not do operation 3. 3- - Complete the command and return it to scsi-ml So the 0x2 in both these operations (1,2) means the scsi check-condition status, hence SAM_STAT_CHECK_CONDITION - Here the code asks about !(DONE_SC->SCp.Status & not_issued) but "not_issued" is an enum belonging to the "phase" member and not to the Status returned from target. The reason this works is because not_issued==1 and Also CHECK_CONDITION==1 (remember from hunk 1). So actually the code was asking !(DONE_SC->SCp.Status & CHECK_CONDITION). Which means "Has the status been read from target yet?" Staus is read at status_run(). "not_issued" is cleared in seldo_run() which is usually earlier than status_run(). So this patch does nothing as far as assembly is concerned but it does let the reader understand what is going on.

[SCSI] aha152x: Fix check_condition code-path check_condition code-path was similar but more complicated to Reset. It went like this: 1. extra space was allocated at aha152x_scdata for mirroring scsi_cmnd members. 2. At aha152x_internal_queue() every not check_condition (REQUEST_SENSE) command was copied to above members in case of error. 3. At busfree_run() in the DONE_CS phase if a Status of SAM_STAT_CHECK_CONDITION was detected. The command was re-queued Internally using aha152x_internal_queue(,,check_condition,) The old command members are over written with the REQUEST_SENSE info. 4. At busfree_run() in the DONE_CS phase again. If it is a check_condition command, info was restored from mirror made at first call to aha152x_internal_queue() (see 2) and the command is completed. What I did is: 1. Allocate less space in aha152x_scdata only for the 16-byte original command. (which is actually not needed by scsi-ml anymore at this stage. But this is to much knowledge of scsi-ml) 2. If Status == SAM_STAT_CHECK_CONDITION, then like before re-queue a REQUEST_SENSE command. But only now save original command members. (Less of them) 3. In aha152x_internal_queue(), just like for Reset, use the check_condition hint to set differently the working members. execute the command. 4. At busfree_run() in the DONE_CS phase again. restore needed members. While at it. This patch fixes a BUG. Old code when sending a REQUEST_SENSE for a failed command. Would than return with cmd->resid == 0 which was the status of the REQUEST_SENSE. The failing command resid was lost. And when would resid be interesting if not on a failing command?
