[PATCH 0/1] coresight: Fix TRCCONFIGR.QE sysfs interface

by James Clark

I was working on refactoring some of the magic numbers for the register accesses and I saw this issue with programming one of the values. I don't have any evidence that someone encountered it not working, probably there is no hardware where QSUPP==0b10, or it just didn't get used yet. But the issue is that this silently writes a reserved value even if the user provided one was correct so it might ruin someones day if it ever comes up. It's a small change so I didn't see the harm in fixing it. Applies to coresight/next f9809d565135 James Clark (1): coresight: Fix TRCCONFIGR.QE sysfs interface drivers/hwtracing/coresight/coresight-etm4x-sysfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) -- 2.17.1

Re: [PATCH] coresight: syscfg: Fix memleak on registration failure in cscfg_create_device

That is _if_ device_initialize() is called manually. In this instance @dev is registered with device_register() and unregistered with device_unregister(). The latter conforms to the comment you pointed out and calls put_device() as expected.

Re: [RESEND PATCH v2] coresight: change tmc from misc device to cdev device

On December 21st you posted this patch with a "RFC V3 PATCH" tag. On January 5th you posted a new version with a simple "PATCH" tag which, minutes later, was superseded by another patch labelled "RESEND PATCH". Today you're sending yet another revision labelled "RESEND PATCH V2"... Is it a "V2" of the "RESEND PATCH" that was a new revision of the "RFC V3 PATCH"? Are you confused? I certainly am... > > Signed-off-by: Jay Chen <jkchen(a)linux.alibaba.com> > --- > .../hwtracing/coresight/coresight-tmc-core.c | 103 ++++++++++++++---- > drivers/hwtracing/coresight/coresight-tmc.h | 11 +- > 2 files changed, 91 insertions(+), 23 deletions(-) > > diff --git a/drivers/hwtracing/coresight/coresight-tmc-core.c b/drivers/hwtracing/coresight/coresight-tmc-core.c > index d0276af82494..0977f1ce6338 100644 > --- a/drivers/hwtracing/coresight/coresight-tmc-core.c > +++ b/drivers/hwtracing/coresight/coresight-tmc-core.c > @@ -12,7 +12,6 @@ > #include <linux/io.h> > #include <linux/err.h> > #include <linux/fs.h> > -#include <linux/miscdevice.h> > #include <linux/mutex.h> > #include <linux/property.h> > #include <linux/uaccess.h> > @@ -31,6 +30,12 @@ DEFINE_CORESIGHT_DEVLIST(etb_devs, "tmc_etb");

[PATCH 1/3] coresight: Add config flag to enable branch broadcast

by James Clark

When enabled, all taken branch addresses are output, even if the branch was because of a direct branch instruction. This enables reconstruction of the program flow without having access to the memory image of the code being executed. Use bit 8 for the config option which would be the correct bit for programming ETMv3. Although branch broadcast can't be enabled on ETMv3 because it's not in the define ETM3X_SUPPORTED_OPTIONS, using the correct bit might help prevent future collisions or allow it to be enabled if needed.

This eases review as in the end this code is just a refactoring, moving things around but in the end should be equivalent code. There are a few more, please consider this and if you agree, to speed things up I can make the changes here, if I think this won't fallout in changes to subsequent patches touching this area. - Arnaldo > static int cmp_aggr_cpu_id(const void *a_pointer, const void *b_pointer) > { > struct aggr_cpu_id *a = (struct aggr_cpu_id *)a_pointer;

BTW, here are the final tests, problems with arm 32 and 64-bit, I'll go thru them tomorrow, to fix in the cset the problem appears, so that we keep it bisectable, else you can get what I have in
