2010-05-12arm: msm: smd: fix SMD modem processor sync conditionDaniel Walker3-1/+24
When booting up we need to wait for the modem processor to partially boot. This is because the modem processor does resource allocation for us. If we don't wait the modem won't honor our requests and we end up crashing or in an unknown state. This change just formalizes the waiting process. Signed-off-by: Daniel Walker <c_dwalke@quicinc.com>
2010-05-12arm: msm: smd: ifdef dsp irq handlerDaniel Walker1-0/+2
This irq handler isn't used in all cases, so add the proper ifdef. This eliminates a compiler warning due to the function not getting used. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-05-12arm: msm: smd: remove unneeded predefinesDaniel Walker1-41/+36
This just removed some unneeded predefines. One needed a whole function moved down further. The others could just be deleted. No functional changes. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-05-12arm: msm: smd: msm7x30 a2m clean upDaniel Walker2-12/+16
This moves the msm_a2m_int() function into the header, and does a small macro clean up to be more inline with Linux norms. No functional changes. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-05-12arm: msm: smd: convert unsigned addr to unsigned longDaniel Walker1-1/+1
"unsigned" translates to "unsigned int", but this value holds an address. We always want to use unsigned long for addresses since it will change size to fit the machine. This just convert the one address holder to unsigned long. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-05-12arm: msm: smd: use either package v3 or v4 not bothDaniel Walker3-48/+78
This modifies SMD to use either the package v3 or package v4, but not both. The current code tries to allocate as v4 on all system which can produce a scary looking error message on boot up, smem_find(16, 40): wrong size 16424 smd_alloc_channel() cid=02 size=08192 'SMD_RPCCALL' With this error the code then falls back on the package v3 allocation method. This method is inefficient because it causes a slow down on some systems even when the allocation method can be determined at compile time. It also causes a kernel size increase that effects all system and is not needed. This change corrects the allocation to use one method or the other and not both.

2010-05-12arm: msm: smd: checkpatch clean up of smd/proc_commDaniel Walker4-24/+17
This cleans up coding style. There are no run time changes. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-05-12[ARM] msm: smd: Force the half_channel struct aligmnent to 4Dima Zavin1-1/+1
Forcing the alignment prevents gcc from generating byte reads for word member variables. Lack of this caused issues when the app processor modified struct members and the modem saw a partial word write.

2010-05-12msm: smd: provide atomic channel writesBrian Swetland2-0/+11
Some smd clients may write from multiple threads, in which case it's not safe to call smd_write without holding a lock. smd_write_atomic() provides the same functionality as smd_write() but obtains the smd lock first.

2010-05-12msm/qsd: smd: avoid race condition in smd channel allocationBrian Swetland1-6/+7
Don't mark a channel as allocated if we failed to allocate it (perhaps the modem updated one table but not the other, etc) Signed-off-by: Brian Swetland <swetland@google.com> Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
2010-05-12[ARM] msm: smd: Update the correct fTAIL pointer after reading from fifoHaley Teng1-1/+1
When we read data out of the sender's fifo, we need to advance the sender's tail pointer, not the receiver's. Signed-off-by: Haley Teng <Haley_Teng@htc.com> Acked-by: Dima Zavin <dima@android.com> Signed-off-by: Daniel Walker <dwalker@codeaurora.org>

2010-05-12[ARM] msm: shared memory interface for baseband processor ipcBrian Swetland6-1/+1625
This code provides the low level interface to the "shared memory state machine" (smsm), and the virtual serial channels (smd), used to communicate with the baseband processor. Higher level transports (rpc, ethernet, AT command channel, etc) ride on top of this. Signed-off-by: Brian Swetland <swetland@google.com>

2010-04-30kgdb: don't needlessly skip PAGE_USER test for Fsl bookeWufei1-5/+0
The bypassing of this test is a leftover from 2.4 vintage kernels, and is no longer appropriate, or even used by KGDB. Currently KGDB uses probe_kernel_write() for all access to memory via the KGDB core, so it can simply be deleted. This fixes CVE-2010-1446.
