Registers 0x300 and 0x304 give us nothing useful and cause hangs when they are read while 3D is running. Remove them from the postmortem dump. Change-Id: I4abb8f2a33eb3e3dd1f92400455710ea87f44736 Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org>
…packet
Remove code setting previously unused field in REG_TO_MEM packet.
As far as I can tell, setting bit 30 ("| (1 << 30)") has never had any
effect. It may originally have been coded to accumulate the value in the
REG_TO_MEM, but that no longer makes any sense in this context, since this
code is being called for regular register values (not perf counters).
Now that the REG_TO_MEM packet is using bits 30:15 as a count on Leia, this
code will attempt to copy 32k (1 << (30-15)) register values. This isn't
correct, so I'm removing this code.
This is CL1619066 from core driver

Some registers on older GPUs are not valid for the Z470 GPU and cause RBBM read errors during the postmortem dump. These are harmless but needlessly detract attention from the actual problems.

Because not all of the 2d registers are directly accessible, the functions for accessing them had gotten a little bit confusing. This removes the apparent mutual recursion at the expense of a little more code. Also, the 2 step registers are now guarded by a spinlock to prevent a possible race.

Rather then just calculating the idle time and returning it, there is value in returning the raw statistics and let the caller use them as they see fit. Rename calc_idle to power_stats, and use a structure to pass back the total_time and busy_time. The structure allows for future expansion as well as providing enough information for others to perform interesting power and load related calculations.

The xt_quota2 came from http://sourceforge.net/projects/xtables-addons/develop It needed tweaking for it to compile within the kernel tree. Fixed kmalloc() and create_proc_entry() invocations within a non-interruptible context. Removed useless copying of current quota back to the iptable's struct matchinfo: - those are per CPU: they will change randomly based on which cpu gets to update the value. - they prevent matching a rule: e.g. -A chain -m quota2 --name q1 --quota 123 can't be followed by -D chain -m quota2 --name q1 --quota 123 as the 123 will be compared to the struct matchinfo's quota member.

The IPv6 tproxy patches split IPv6 defragmentation off of conntrack, but
failed to update the #ifdef stanzas guarding the defragmentation related
fields and code in skbuff and conntrack related code in nf_defrag_ipv6.c.
This patch adds the required #ifdefs so that IPv6 tproxy can truly be used
without connection tracking.
